VSS between two Cisco 6509, closet sw's are 3750s but clostes are coming up and going up!?

                   Hello,

we have two Cisco 6509 switches with one SUP and configured with VSS acting as core swithes. closet switches stack of 3750's connect to these two core siwthces. the closet swithces are comeing up and going down and we cannot pinpoint the issue. I am going there to see but based on my understabding the cause could be the VSS switching continously between Active and non-active or master/slave!? I wanted to see what you guys think about this please.gards,

Please advise,

Regards,

Masood

Hi Reza,

Infor attached.

I see that no :


No interfaces excluded from shutdown in recovery mode

In dual-active recovery mode: No

had been defined so that might explian why the master sw is in inactive mode!? Please advise.

I had not intially configre this sw but here to troubleshoot it and have not done VSS before.

Hi Masood,

Can you provide "sh run" from the VSS pair?

Also, can you provide "sh swit virt det" and "sh swi vir link"?

Can you please post the "sh logs" of both the 6500 and the 3750?  I exactly want to see the said interfaces bouncing and the relevant information about it.

Can you also post the interface configurations too?
