Cisco VSS -Standby Switch powering on

[saxenanitesh8522]

hi,

I wanted to know, if my secondary/standby is powered off and i need to power on the standby switch.

Do i need to restart both of the switches active and standby to detect the VSS configuration. 

Or just starting the standby by itself should be fine? that it will detect the active VSS switch and sync by itself.

What is the best way of doing this.

Hello

if the standby switch was already in vss mode then yes you can re activate it- Otherwise my understanding is no you cannot just attach a new switch and then create the vss.

When you establish a vss the switches default their configuration and both require a reload, then they come back as a vss stack as active/standby modes with the vsl link monitoring either switch.

The sequence when a vsl failure occurs and Dual active detection is enabled would consist of the active switch going in to suspend mode and the standby switch going active and as/when the vsl link is reestablished the now suspended switch will reload agin and become the standby switch
