firm] Alternatively, you can reload either switch by appending the shelf (switch) number to the same command: VSS# redundancy reload shelf 2 Reload the entire remote shelf[confirm] To specifically force a failover, use the redundancy force-switchover command. The active switch will be reloaded to force the switchover. I don't know of a way to force a switchover without reloading the active chassis, SO don't do this lightly-remember, it will take up to 15 minutes to reload the chassis: VSS# redundancy force-switchover This will reload the active unit and force switchover to tandby[confirm] To see when the last failover occurred, use the show redundancy switchover command: VSS#sho redundancy switchover Switchovers this system has experienced Last switchover reason active unit removed Uptime since this supervisor switched to active hours, 14 minutes Total system uptime from reload 3 hours, 32 minutes Miscellaneous VSS Commands Hardware-specific commands will usually have a new modifier to allow the user to view either switch's equipment. For example, the show module command now includes the switch modifier: VSS#sho module switch ? <1-2> Virtual switch number show all linecard module information version show all linecard version information Output modifiers Take care here, because the output of the show module command only includes infor- mation for the active chassis and does not indicate which chassis is being displayed. To show the modules for both switches, use the show module switch all command. Similarly, the show environment command now includes a switch modifier, though this command defaults to showing both switches without the modifier: VSS#sho env switch ? <1-2> Virtual switch number Chapter 17: Cisco 6500 Multilayer Switches VSS Best Practices Cisco has a document outlining its VSS best practices. The document should be re- quired reading if you're going to take on a VSS install or existing VSS environment.
