Hi All,

I have 2 6509 VSS switch in my environment, its currently running with 15.0 IOS and now I would like to upgrade it with 15.1

2 VSS are in differnt location, what are steps to upgrade them?? do i need to visit each switch and upgrade them or remotely can i perform upgrade ??

Thanks

You can do it remotely.  The easiest way is to have an outage window for about one hour.  Load the new image into the primary and stand-by sups, set the boot variable and reboot both chassis at the same time.

...it may be better to use Enhanced Fast Software Upgrade (eFSU) in VSS case?

You don't need to.  when you issue the reload command on the primary switch, it will reboot both primary and stand-by.

Thanks for your reply....

but I would like to know how to load new 15.1 IOS on both, do I need to console login to both switches ??and load the new IOS then reload right ?

Thanks

In VSS, you only have access to primary switch.  Load the new IOS in to

sup-bootdisk and slave sup-bootdisk.

sup-bootdisk is for the primary switch and slave sup-bootdisk is for stand-by switch

Delete the old boot variable command and set the new one.

save the config

reboot both switches.
