VSS Quad on 4500 Example Configuration.

[Lucio Garrido]

Hi community,

                  I need your support over how to configurate a VSS on switch 4500 with 2 supervisor in each device. I have this document with this reference but no is very clear. Please someone that knows about this configuration:

http://www.cisco.com/c/en/us/support/docs/switches/catalyst-4500-series-switches/118597-config-vss-00.html

The document reference say me that I need to configure the actives supervisor of each switch in VSS and colocate this supervisors (VSS) in rommon mode, after I continue with the configuration of the supervisors active (before stadby), but simply place the supervisor in rommon mode or is besf to turn off the supervisors active and finish your configuration and after continue with the others supervisor (standby) in the same mode.

I hope I have been clear, thank you for your attention and promt response.

Regards!

Hi,

I have never done quad sup VSS, but according to the document you posted, there is no need to turn off the stand-by supervisor. You just reboot the chassis using the software, but need to have console access, so you can stop the boot process on the stand-by sups.

I recommend you test this multiple times and document it well, so when something goes wrong during production you or others know exactly what to do, if not quad sup VSS recovery can become disaster.
