How to upgrade C4510R+E with 2 x SUP8E with zero downtime?

[Jagan1976]

Hi guys,

I need some advice on how to upgrade a 4510R+E switch with 2 x WS-X45-SUP8-E modules without any downtime?

The reason is it came with a non k9 ipbase software and I would like to install the same version but with k9 ipbase.

The license is correct and is ipbase so there should be no license issue.

Thanks in advance!

VSS upgrade, using ISSU, FSU/eFSU, would work if each downstream device is dual-homed.

Hi Leo,

Thanks for your reply. I do not understand. The current systems is in standalone system and the SUPs are in SSO mode.

Same process applies.
