Thanks guys, that is more what I was looking for.
Below are the steps I was going to take, let me know if this looks okay:
ON New switch:
- empty config except for root password is set, I can't commit a totally empty config so I left that
- configured SFP ports to be VC ports
ON Existing switch:
- configure SFP ports to be VC ports
- set virtual chassis preprovisioned
- set virtual chassis no split detection
- commit config
Connect new switch to existing switch, then power on new switch
- set virtual chassis member 0 role RE
- set virtual chassis member 0 serial-number xxxxx
- set virtual chassis member 1 role RE
- set virtual chassis member 1 serial-number xxxxx
- commit
set system commit synchronize
set chassis redundancy graceful-switchover
set protocols layer2-control nonstop-bridging
commit
Should I then do a power cycle when all this is complete?
Thanks again!
