Cisco VSS clarification
Posted on 2012-08-26
At a customer site, there is currently two Catalyst 6509-E chassis populated with line cards and supervisor modules (WS-SUP720-3BXL). The two Catalyst switches aggregate all connections from the many client access switches. Everything is working fine.
The tricky part is that one of the Catalyst 6509-E has two supervisor modules (WS-SUP720-3BXL) in slots 5 and 6 with one being active and the other in hot standby mode.
Now, there is a need to implement VSS on these switches. Two VSS-capable supervisor modules (VS-S720-10G-3C) have been purchased.
I intend to replace the existing supervisor modules with the VSS-capable ones and then deploy VSS across the two chassis.
My question here is;
1) Should i take out the hot standby supervisor as well from the chassis that presently contains two supervisors.
2) What are the implications if i leave the hot standby module in place after implementing VSS.. Can bad things happen.
My thinking is to take out both supervisors. I just want to be sure that I am not missing out on anything i should know.
Please note that implementing VSS is not an issue for me, as i have experience deploying VSS. I just havent deployed at a site that has two supervisors in one chassis. I have often run into situations where there is only one supervisor in each chassis.
Thanks in anticipation.
