If the VSL is down when both switches try to boot up, the situation is similar to a dual-active scenario. One of the switch becomes VSS Active and the other switch initiates recovery from the dual-active scenario. The following sections describe restrictions and guidelines for VSS configuration:. When configuring the VSS, note the following guidelines and restrictions:. Please remove all other linecards from your system when converting from standalone to VSS mode.
After the running configuration is saved and a shelf reload occurs, this behaviour is not observed - the entPhysicalDescr objects for both chassis accurately reflects the correct chassis types. When configuring MECs, note the following guidelines and restrictions:.
When configuring dual-active detection, note the following guidelines and restrictions:. The active switch can gather information from all switches that are Layer 3 reachable. Note Both switches are directly connected to each other using Layer 3 physical interfaces and are reachable through these interfaces. These physical interfaces are candidate VSL interfaces and are displayed in a list of "potential" VSL interfaces in the output of the vsl?
This output also displays a list of indirectly-reachable Layer 3 interfaces. Management and user-created VRF are not supported. Note Switches are reachable to each other through management interfaces. Reachability to neighboring switches using a management interface isn't supported although the management interface appears in the candidate VSL list.
Switches can be Layer 3 reachable indirectly but directly connected. The directly-connected physical interfaces display in the output of the vsl? Selects interface and switches to interface configuration mode. Switch config-if ip add a. Issuing the switch convert mode easy-virtual-switch exec command on a VSS active switch displays a list of potential VSS standby switches - those that are directly connected and hardware compatible. From the displayed list, the sub-command vsl?
Perform the following task on the VSS active switch that you want to make the master switch, which manages the standby switch after VSS boot-up:. Switch switch convert mode easy-virtual-switch. Switch easy-vss VSL? Displays a list of local inter-faces with their peer interfaces, switch-ip and switch-name.
Assigns the local interfaces that we want to convert to VSL. The following example illustrates use of the vsl? The switch on which we execute the above commands becomes the master switch after VSS boots. Local Interfaces lists interfaces on the switch where we are executing the commands. Remote Interfaces lists the interfaces on the peer switch connected with the local interfaces. Select a maximum of eight VSL local interfaces i. This example forces both the master and standby switches to reboot and come up in VSS.
Note 10G and 1G interfaces cannot be mixed. Chosen interfaces should belong to the same peer. The master switch shares the tftp image path with the standby switch. On reboot, if the tftp path is used for loading the image, both switches boot with the same image.
The VSS combines two standalone switches into one virtual switch, operating in virtual switch mode. Note Preferably, conversion to VSS should be done on a maintenance window. If you plan to use the same port channel number for VSL, default the existing port channel configurations that are available on standalone switches.
To convert two standalone switches into a VSS, you perform the following major activities:. In virtual switch mode, both switches use the same configuration file. The tasks required to convert the standalone switch to a VSS are detailed in the following sections:.
In the procedures that follow, the example commands assume the configuration shown in Figure Note The port channels 10 and 20 mentioned in the config steps below are merely exemplary. You can configure any port channel number from for VSL port channel. Save the configuration files for both switches operating in standalone mode.
You need these files to revert to standalone mode from virtual switch mode. Switch-1 copy running-config startup-config. Optional Saves the running configuration to startup configuration. Switch-1 copy startup-config bootflash:old-startup-config.
Switch-1 copy startup-config slot0:old-startup-config. Copies the startup configuration to a backup file. Switch-1 copy startup-config slavebootflash:old-startup-config. Switch-1 copy startup-config slaveslot0:old-startup-config. Copies the startup configuration to the standby supervisors. You must configure the same virtual switch domain number on both switches of the VSS. The virtual switch domain is a number between 1 and , and must be unique for each VSS in your network the domain number is incorporated into various identifiers to ensure that these identifiers are unique across the network.
Within the VSS, you must configure one switch to be switch number 1 and the other switch to be switch number 2. To configure the virtual switch domain and switch number on both switches, perform this task on Switch Switch-1 config switch virtual domain Switch-1 config-vs-domain switch 1.
Switch-1 config-vs-domain exit. Switch-2 config switch virtual domain Switch-2 config-vs-domain switch 2. Switch-2 config-vs-domain exit. Note The switch number is not stored in the startup or running configuration, because both switches use the same configuration file but must not have the same switch number. The VSL is configured with a unique port channel on each switch.
To avoid this situation, check that both port channel numbers are available on both of the switches. Check the port channel number with the show running-config interface port-channel command. The command displays an error message if the port channel is available for VSL.
For example, the following command shows that port channel 20 is available on Switch To configure the VSL port channels, perform this task on Switch Note The port channels 10 and 20 mentioned in the configuration steps below are exemplary only. Switch-1 config interface port-channel Switch-1 config switchport. Switch-1 config-if switch virtual link 1. Switch-1 config-if no shutdown. Switch-1 config-if exit. Switch-2 config interface port-channel Switch-2 config-if switch virtual link 2.
Switch-2 config-if no shutdown. Switch-2 config-if exit. You must add the VSL physical ports to the port channel. Tip For line redundancy, we recommend configuring at least two ports per switch for the VSL. For module redundancy, the two ports can be on different switching modules in each chassis.
To configure the VSL ports, perform this task on Switch Switch-1 config-if channel-group 10 mode on. Switch-2 config-if channel-group 20 mode on. Conversion to virtual switch mode requires a restart for both switches. A backup copy of the startup configuration file is saved in bootflash. This file is assigned a default name, but you are also prompted to override the default name if you want to change it. To convert Switch 1 to virtual switch mode, perform this task:. Switch-1 switch convert mode virtual.
After you enter the command, you are prompted to confirm the action. Enter yes. The system creates a converted configuration file, and saves the file to the bootflash of the VSS active supervisor. To convert Switch 2 to virtual switch mode, perform this task on Switch Switch-2 switch convert mode virtual. The system creates a converted configuration file, and saves the file to the bootflash. Note After you confirm the command by entering yes at the prompt , the running configuration is automatically saved as the startup configuration and the switch reboots.
When switches are being converted to VSS, you should not set them to ignore startup-config. If done, the switch can be enabled to parse the startup-config at the rommon prompt. Ignoring startup-config in VSS mode, causes a switch to boot in a semi-VSS mode, which can only be corrected by a reboot and by enabling the parsing of startup-config. Step 2 Insert the redundant supervisors in the appropriate slots.
The in-chassis active supervisor then syncs its startup configuration to the ICS. The ICS bootflash filesystem is mounted with the name bootflash-ics:. Note You cannot configure or provision modules on VSS. When switches form initial VSS relationships, they send module information to each other and this information is pushed to the configuration and used subsequently for provisioning, provided the switch is booting and the peer is down or not present.
The following example shows the module provisioning information:. These commands are not available to the user and that various numbers used in these commands are internal to the system and used to identify a module. These commands are written to the startup-config when a switch detects a given module while it is running in VSS mode. When reconverted to standalone mode, these commands are removed from the startup-config.
To display basic information about the VSS, perform one of these tasks:. Switch show switch virtual. Displays the virtual switch domain number, and the switch number and role for each of the switches. Switch show switch virtual role. Displays the role, switch number, and priority for each of the switch in the VSS. Switch show switch virtual link. The following example shows the information output from these commands:. To convert a VSS into two standalone systems, you perform the following major steps:.
Save the configuration file from the VSS Active switch. You may need this file if you convert to virtual switch mode again. This step is only required if there are unsaved changes in the running configuration that you want to preserve. Switch-1 copy startup-config bootflash:vs-startup-config.
When you convert the VSS Active switch to standalone mode, the VSS Active switch removes the provisioning and configuration information related to VSL links and the peer chassis modules, saves the configuration file, and performs a reload. The switch comes up in standalone mode with only the configuration data relevant to the standalone system. VSL links on this switch are down because the peer is now unavailable. Switch-1 switch convert mode stand-alone. Conversion from VSS to standalone causes all physical interfaces to be administratively shutdown and written to the startup-config.
This is a safeguard against a standalone system arriving in the network alive and conflicting with a bridge or router MAC address, which might still be there if one of the VSS switches is still running in VSS mode. We do not recommend that you convert a VSS to standalone in a live network. When you convert the new VSS Active switch to standalone mode, the switch removes the provisioning and configuration information related to VSL links and the peer switch modules, saves the configuration file and performs a reload.
The switch comes up in standalone mode with only its own provisioning and configuration data. To convert the peer switch to standalone, perform this task on the VSS Standby switch:. Switch-2 switch convert mode stand-alone.
These sections describe how to configure VSS parameters:. To configure the switch priority, perform this task:. Switch config switch virtual domain Enters configuration mode for the virtual switch domain. Configures the priority for the switch. The switch with the higher priority assumes the VSS Active role.
The range is 1 lowest priority to highest priority ; the default is The show switch virtual role command displays the operating priority and the configured priority for each switch in the VSS. Note If you make configuration changes to the switch priority, the changes only take effect after you save the running configuration to the startup configuration file and perform a reload.
The show switch virtual role command shows the operating and configured priority values. This example shows how to configure virtual switch priority:. This example shows how to display priority information for the VSS:. To configure a port channel to be a VSL, perform this task:. Enters configuration mode for the specified port channel. Assigns the port channel to the virtual link for the specified switch. At any time, you can add and delete VSL ports from a port-channel to increase the nunber of links in the VSL, to move the port from one port to another, or to remove it from VSL.
Before adding or deleting VSL ports, do the following:. To display information about the VSL, perform one of these tasks:. Switch show switch virtual link port-channel. Switch show switch virtual link port. This example shows how to display VSL information:.
When a physical port is configured as a member of a VSL port-channel, a queuing policy is automatically attached to the VSL member ports. Each queue is provided with a minimum bandwidth, ensuring that VSS management and control protocol packets are not dropped when congestion occurs on the VSL. The bandwidth assigned to a class of traffic is the minimum bandwidth that is guaranteed to the class during congestion.
The following command sequence is inserted automatically by software. On VSS, all routing protocols are centralized on the active supervisor engine. A common router MAC address is used for Layer 3 interfaces on both active and standby switches. Additionally, to ensure non-stop forwarding, the same router MAC address is used after switchover to Standby, so that all layer 3 peers see a consistent router MAC address.
By default, the virtual domain based router MAC address is used. The follow table shows how to configure the router MAC address. Switch config-vs-domain mac-address use-virtual. Assigns the router MAC address from a reserved pool of domain-based addresses. This is shown in the configuration, even if it the default. Switch config-vs-domain mac-address mac-address. Assigns the router MAC address in three 2-byte hexadecimal numbers.
Switch config-vs-domain mac-address chassis. You can verify the MEC configuration by entering the show etherchannel command. These sections describe Layer 3 EtherChannel configuration:. Note To move an IP address from a physical interface to an EtherChannel, you must delete the IP address from the physical interface before configuring it on the port channel interface. To create a port channel interface for a Layer 3 EtherChannel, perform this task:. Creates the port channel interface.
Assigns an IP address and subnet mask to the EtherChannel. This example shows how to create port channel interface This example shows how to verify the configuration of port channel interface To configure physical interfaces as Layer 3 EtherChannels, perform this task for each interface:.
Ensures that no IP address is assigned to the physical interface. If you use PAgP, enter the keywords auto or desirable. If you use LACP, enter the keywords active or passive. This example shows how to verify the configuration of port channel interface 1 after the interfaces have been configured:. This example shows how to display a one-line summary per channel group:. The following sections describe how to configure dual-active detection:.
By default, PAgP dual-active detection is enabled. However, the enhanced messages are only sent on port channels with trust mode enabled see the trust mode description in the note. Note Before changing PAgP dual-active detection configuration, ensure that all port channels with trust mode enabled are in administrative down state.
Use the shutdown command in interface configuration mode for the port channel. Remember to use the no shutdown command to reactivate the port channel when you are finished configuring dual-active detection. To enable or disable PAgP dual-active detection, perform this task:. Switch config-vs-domain dual-active detection pagp. You must configure trust mode on the port channels that will detect PAgP dual-active detection.
By default, trust mode is disabled. Note If PAgP dual-active detection is enabled, you must place the port channel in administrative down state before changing the trust mode. Remember to use the no shutdown command to reactivate the port channels when you are finished configuring trust mode on the port channel. To configure trust mode on a port channel, perform this task:.
Enables trust mode for the specified port channel. This example shows how to enable PAgP dual-active detection:. This example shows the error message if you try to enable PAgP dual-active detection when a trusted port channel is not shut down first:.
This example shows the error message if you try to configure trust mode for a port channel that is not shut down first:. To configure an interface as part of a dual-active detection pair, you need to configure dual-active fast-hello on the interface.
Although fast hello dual-active detection is enabled by default, you must configure dual-active interface pairs to act as fast hello dual-active messaging links. To enable or disable fast-hello dual-active detection, perform this task:. Switch config-vs-domain dual-active detection fast-hello. Enables the fast hello dual-active detection method.
Note Fast hello dual-active detection is enabled by default. Switch config-vs-domain exit. Note This interface must be directly connected to the other chassis and must not be a VSL link. Switch config-if dual-active fast-hello. Enables fast hello dual-active detection on the interface, automatically removes all other configuration from the interface, and restricts the interface to dual-active configuration commands. Switch config-if no shutdown. Switch config-if exit.
Switch config exit. Displays status of dual-active fast-hello configuration. When you configure fast hello dual-active interface pairs, note the following information:. This example shows how to configure an interface for fast hello dual-active detection:. To display information about dual-active detection, perform this task:.
Displays information about dual-active detection configuration and status. This example shows how to display the summary status for dual-active detection:. This example shows how to display the summary status for dual-active detection when recovery is triggered by RRP rather than PagP:.
This example shows how to display PAgP status and the channel groups with trust mode enabled:. This example shows how to display the status of links configured as fast-hello:. This example shows how to display the status of packet exchanges between the individual fast-hello links:.
This example shows how to display the status of total packets exchanged between the fast-hello links on the VSS:. In a VSS, the supervisor engines on the peer switches maintain an SSO stateful switchover relationship between themselves. This facilitates the ability to perform a software upgrade or downgrade on both the VSS supervisor engines. Figure below depicts at a conceptual level the sequence of events that take place when the VSS system is upgraded from software version X to version Y.
Figure indicates that both switches in a VSS reboot at some point during the upgrade process. When a switch reboots, all the network links that terminate on that switch undergo a link-down event. This means that network devices that are connected to the switch that is rebooting will observe a disruption in service, unless the connection is over an MEC that contains at least one link that terminates on the other switch.
If a peer device is connected to the VSS over an MEC that has links terminating in both switches, that device will not experience a disruption of service during the software upgrade process. This is illustrated in Figure Before performing ISSU, you must meet these prerequisites:. You can enter various commands on the switch to determine supervisor engine versioning and Cisco IOS XE software compatibility. Both supervisor engines should be running the pre-upgrade image, and should have booted from the image location in the local file system.
Note The show version command can be used to confirm that the supervisor engine has actually booted from the pre-upgrade image location in the local filesystem. The config-register value displayed in the output of show version can be used to confirm this. Before you perform ISSU, you should understand the following concepts:.
A fifth command, issu abortversion, enables you to abort the ISSU upgrade process at any time, and to revert to the initial system state. The VSS continues to operate throughout the entire process; however as explained in Traffic and Network Protocol Disruption During ISSU in a VSS , service is disrupted on network links that terminate on interfaces that reside in the switch that is undergoing a reboot. Figure depicts the states through which the VSS Active and standby supervisor engines progress as the sequence of four commands entered.
It also shows the effect of the issu abortversion command at any given point during the process. During the ISSU process, several show commands are available to evaluate the success of each command before proceeding to the next step. The use of multiple ISSU commands dictates an additional level of care to ensure no service disruption. However, in some scenarios, this upgrade procedure might be cumbersome and of minimal value.
A typical example is during a network upgrade that involves performing an ISSU upgrade on a large number of Catalyst switches. In these cases, we recommend that you first perform the manual four command ISSU upgrade procedure on one VSS possibly in a lab environment to verify successful upgrade. Then, use the single issu changeversion procedure to perform an automatic ISSU on the rest of the Catalyst switches in the network.
The issu changeversion command launches a single-step complete ISSU upgrade cycle. It performs the logic for all four of the standard commands issu loadversion, issu runversion, issu acceptversion, and issu commitversion without user intervention, streamlining the upgrade through a single CLI step.
Additionally, issu changeversion allows the upgrade process to be scheduled for a future time. This enables you to stage a number of systems to perform upgrades sequentially when a potential disruption would be least harmful. Hence, a reset on any RP will keep the system booting the new software image. Console and syslog messages will be generated to notify anyone monitoring the upgrade that the state transition has occurred.
Similar to the normal ISSU upgrade procedure, the in-progress upgrade procedure initiated by the issu changeversion command can be aborted with the issu abortversion command. If the system detects any problems or detects an unhealthy system during an upgrade, the upgrade might be automatically aborted. When the issu runversion command is entered during the four step manual upgrade process, if any incompatible ISSU clients exist, the upgrade process reports them and their side effects, and allows the user to abort the upgrade.
While performing a single-step upgrade process, when the process reaches the runversion state, it will either automatically continue with the upgrade provided the base clients are compatible, or automatically abort because of client incompatibility. When the quick command option is applied, the ISSU upgrade state transition differs from that illustrated in Figure With this option, the state progression upto the loadversion stage remains the same as described in the figure, but the runversion and commitversion stages are combined.
This progression skips the step in the upgrade procedure that loads the old software version on the new standby old active supervisor, thereby reducing the time required for the automatic ISSU upgrade by about a third. The at command option schedules an automatic ISSU upgrade to begin at a specific time. This option specifies an exact time hh:mm, 24 hour format in the next 24 hours at which the upgrade will occur. The in command option schedules an automatic ISSU upgrade to begin after a certain amount of time has elapsed.
This option specifies the number of hours and minutes hh:mm format that must elapse before an upgrade will occur, with a maximum value of The typical issu changeversion command usage scenario is for experienced users with a large installed base. These users typically validate a new image using a topology and configuration similar to their production network.
The validation process should be done using both the existing multi-command process and the new issu changeversion command process. Once users certify an IOS XE software image and want to roll it out broadly, they can use the single command process to perform an efficient upgrade of their network. The issu changeversion command functionality is designed to perform an ISSU software upgrade without user intervention. However, status messages are displayed to the console as the upgrade transitions through the various states.
If any anomalies are noticed during the automatic upgrade, perhaps with peers or other parts of the network, you can use the issu abortversion command to manually abort the upgrade at any point in the process prior to the commitversion operation. Be aware of the following guidelines while performing the ISSU process:. Note Enabling them will cause the system to enter RPR mode because commands are only supported on the new version. ISSU requires additional information to determine compatibility between software versions.
Therefore, a compatibility matrix is defined that contains information about other IOS XE software image with respect to the one in question. This compatibility matrix represents the compatibility of two software versions, one running on the active and the other on the standby supervisor engine, and to allow the system to determine the highest operating mode it can achieve.
Incompatible versions will not be able to progress to SSO operational mode. The matrix stores compatibility information between its own release and prior releases. It is always the newest release that contains the latest information about compatibility with existing releases in the field.
The compatibility matrix information stores the compatibility among releases as follows:. To display the compatibility matrix data between two software versions on a given system, enter the show issu comp-matrix stored command. Note This command is useful only for verification purposes because it is available only after the ISSU process has started.
You might want to check the compatibility matrix prior to starting ISSU. During the ISSU process, there are five valid states: disabled, init, load version, run version, and system reset. Use the show issu state command to obtain the current ISSU state:. Switch show issu state [ detail]. Switch show redundancy. Displays current or historical status, mode, and related redundancy information about the device. Identifies which switch of the VSS is currently performing the Active role, and which switch the Standby.
This example shows how to display the state and the current status of the supervisor engine during the ISSU process:. The following example displays verification that the system operating correctly as a VSS. Ensure that both the supervisor engines are configured to auto-boot, and that they have currently been booted from the pre-upgrade image residing on the local file system. This is verified by the values of the BOOT variable and the configuration register refer to the sample output of show redundancy command in the previous section.
Ensure that the active and standby supervisor engines are up and in ISSU Init state and that both supervisor engines are running the same current image. The following example displays the ISSU state before the process begins:. Note that the Standby slot number is reported as 11, which is a Virtual Slot number that corresponds to physical slot 1 on Switch 2.
The correspondence between the Virtual Slot number and the physical location of the slot can be determined using the show switch virtual slot-map command, as shown in the following example:. The directory information displayed for each of the supervisor engines shows that the new version is present. This task describes the first step of the ISSU four-command sequence, loadversion, wherein the standby supervisor engine is loaded with the post-upgrade image.
Perform the following steps at the active supervisor engine:. Switch issu loadversion [ active-slot] active-image-new [standby-slot] standby-image-new. It may take several minutes after entering the issu loadversion command for Cisco IOS XE software to load onto the standby supervisor engine and for the standby supervisor engine to transition to SSO mode.
This causes the standby supervisor engine to reload with the new software image. If used, the active-slot and standby-slot numbers should be specified as Virtual Slot numbers. Use the show switch virtual slot-map command to determine the correspondence between Virtual slot numbers and their physical locations.
Switch show issu state [ detail ]. It may take several minutes after entering the issu loadversion command for Cisco IOS XE software to load onto the standby supervisor engine and the standby supervisor engine to transition to SSO mode.
If you enter the show issu state command too quickly, you may not see the information you need. Switch show redundancy [states]. This task describes the second step of the ISSU four-command sequence, runversion, wherein a switchover occurs and the standby supervisor engine, which is now loaded with the post-upgrade image, takes over as the new Active.
At the end of the loadversion step, the following message is logged:. Perform the following steps at the active supervisor engine. Switch issu runversion [ standby-slot] [standby-image-new]]. Forces a switchover from the active to the standby supervisor engine and reloads the former active current standby supervisor engines with the old IOS XE image.
As with any SSO switchover, you are prompted to save the running configuration if you have changed it. Respond as appropriate. When you enter the issu runversion command, an SSO switchover will be performed, and NSF procedures will be invoked if so configured. Displays the state of the during the ISSU process. At this point in the ISSU process, use this command to check that a switchover occurs to slot This example shows how to cause a switchover to the former standby supervisor engine slot 11 , reset the former active supervisor engine and reload it with the old IOS XE software image so it becomes the standby supervisor engine:.
A switchover happens at this point. At the new active supervisor engine, do the following after old active supervisor engine comes up as standby. Note The new active supervisor engine is now running the new version of software, and the standby supervisor engine is running the old version of software and is in the standby hot state.
Once Runversion has completed, the new active supervisor engine will be running the new version of software and the previously active supervisor engine will now become the standby supervisor engine. The standby supervisor engine will be reset and reloaded, but it will remain on the previous version of software and come back online in Standby hot status.
Use the show redundancy, show redundancy states, and show issu state [detailed] commands described previously to verify that the standby supervisor engine is running the pre-upgrade version and that the Active is running the post-upgrade version.
This step is optional. It is needed only if you wish to stop the ISSU rollback timer. Otherwise you may proceed to the next step commitversion. Cisco IOS XE software maintains an ISSU rollback timer to safeguard against an upgrade that may leave the new active supervisor engine in a state in which communication with the standby supervisor engine is severed. By default, this duration is 45 minutes. If the commitversion command is not applied before the rollback timer duration expires, the VSS reverts to the pre-upgrade version.
The acceptversion command stops the rollback timer. This means that you can maintain the system in the current state runversion, with the post-upgrade version running on the active supervisor engine, and pre-upgrade image running on the standby supervisor engine for an extended duration, and proceed to the commitversion state only when you are satisfied with the behavior of the post-upgrade software version. This optional task describes how to stop the rollback timer.
Switch issu acceptversion [ active-slot] [active-image-new]]. Enter the issu acceptversion command within the time period specified by the rollback timer to acknowledge that the supervisor engine has achieved connectivity to the outside world; otherwise, the ISSU process is terminated, when the rollback timer expires, and the system reverts to the previous version of Cisco IOS XE software by switching to the standby supervisor engine.
Switch show issu rollback-timer. Displays the amount of time left before an automatic rollback will occur. This example displays the Timer before you stop it. The commitversion step reloads the standby supervisor engine with the post-upgrade image. Switch issu commitversion [standby-slot] [standby-image-new]. At this point in the ISSU process, use this command to check that the standby supervisor engine is loaded with the new image.
This example shows how to reset and reload the current standby supervisor engine slot 1 with the new Cisco IOS XE software version. After you enter the commitversion command, the standby supervisor engine boots in the Standby Hot state. As in prior states, the show redundancy, show redundancy states, show issu state [detailed], and show switch virtual commands can be used to verify that the VSS has reached the desired state. At the end of the commitversion state, the ISSU process has completed.
This task describes how to use the issu changeversion command to perform a one step ISSU upgrade. Switch issu changeversion [active-slot active-image-new]] [standby-slot [standby-image-new]] [at hh:mm in hh:mm] [quick]. Initiates a single-step complete upgrade process cycle. Performs the logic of the four standard commands issu loadversion, issu runversion, issu acceptversion, and issu commitversion without user intervention.
Use the show switch virtual slot-map command to determine the virtual slot number from the physical slot number. Provides an exact time hh:mm, 24 hour format in the next 24 hours when the upgrade will occur. Provides the number of hours and minutes hh:mm format that will elapse before an upgrade will occur max. This example shows how to initiate an ISSU upgrade process using the issu changeversion command.
The outputs of the show switch virtual, show issu state detail, show redundancy, and show redundancy states commands are included to show the supervisor state before and after the upgrade procedure. A Stateful Switchover occurs. Switch 2 takes over as the Active switch.
From this point on, the console logs are gathered on Switch 2. Switch 1 goes down again, then boots up this time with the post-upgrade image , and comes up as SSO Hot Standby. The following example shows how to use issu changeversion with the "at" command option to schedule an ISSU upgrade procedure to automatically start at the specified time. This example specifies that the ISSU upgrade should be started at 24 hour format. You can abort the ISSU process at any stage manually prior to entering the issu commitversion command by entering the issu abortversion command.
The issu abortversion command may also be issued after entering the issu changeversion command while the automatic ISSU upgrade is still in progress. The ISSU process also aborts on its own if the software detects a failure. Note If you enter the issu abortversion command before the standby supervisor engine becomes hot, the traffic might be disrupted.
If you abort the process after you issue the issu loadversion command, the standby supervisor engine is reset and reloaded with the original software. If the process is aborted after you enter either the issu runversion or issu acceptversion command, then a second switchover is performed to the new standby supervisor engine that is still running the original software version.
The supervisor engine that had been running the new software is reset and reloaded with the original software version. Note Ensure that the standby supervisor is fully booted before issuing the abortversion command on an active supervisor engine. Perform the following task on the active supervisor engine:.
Switch issu abortversion [active slot [active-image-new]]. Cancels the ISSU upgrade or downgrade process in progress and restores the switch to its state before the process had started. This example shows how to abort the ISSU process on slot number 11, the slot for the current active supervisor engine. In this example, the ISSU upgrade process is in the Runversion state when the issu abortversion command is entered:.
Cisco IOS XE software maintains an ISSU rollback timer, to safeguard against an upgrade that may leave the new active supervisor engine in a state in which communication with the standby supervisor engine is severed. You may want to configure the rollback timer to fewer than 45 minutes the default so that you need not wait in case the new software is not committed or the connection to the switch was lost while it was in runversion mode. Conversely, you may want to configure the rollback timer to more than 45 minutes in order to have enough time to verify the operation of the new Cisco IOS XE software before committing the new software image.
The ISSU rollback timer kicks in immediately after issu run version is entered so that the minimum value configured should be more than the time required for a chassis reload. Else, the process fails. Note The valid timer value range is from 0 to seconds two hours.
A value of 0 seconds disables the rollback timer. Once you are satisfied that the new image at the active supervisor engine has been successful and you want to remain in the current state, you may indicate acceptance by issuing the issu acceptversion command, which stops the rollback timer.
Issuing the issu commitversion command at this stage is equal to entering both the issu acceptversion and the issu commitversion commands. Use the issu commitversion command if you do not intend to run in the current state for a period of time and are satisfied with the new software version.

In this matrix, the software tries to locate the IOS XE version number that is running on the other supervisor engine that is, the lower or earlier version number. If this information is missing, the ISSU upgrade cannot proceed. This means that the ISSU compatibility for the specified version is dynamically computed, as illustrated with the following example:.
SG is compatible with this version, and the end result is guaranteed to succeed. SG is e permitted. However, the end result will depend upon the ability of individual software features comprising the two versions to successfully complete the ISSU negotiation. IOS XE version SG is not in the list. SG is not possible.
It contains information about how the different software components comprising the IOS XE images on the two supervisor engines were able to negotiate their states. So, this data is useful for troubleshooting failed ISSU upgrade operations. To display information about the ISSU compatibility matrix, perform this task:. Enables privileged EXEC mode.
