Replacing 6807 VSS Standby Sup with RMA Sup

[misaleh]

After setting up the VSS configuration for the new sup2T and reloading it, will I need to reload the active switch as well? I don't want to have to reload the active switch since we cant afford to have any downtime atm.

Also, is the below configuration all I need to do on the new standby supp?

Router# mode sso

Router(config)# switch virtual domain #

Router(config-vs-domain)# switch 2

Router(config)# interface port-channel #

Router(config-if)# switch virtual link 2

Router(config)# interface range tengigabitethernet <intid>

Router(config-if)# channel-group 20 mode on

Router# switch convert mode virtual

is this Dual sup in the same chassis?

if you replaced standby Sup, you do not need to reload.
