Virtual Switch System (VSS) - Standby chassie interfaces do not show

jhonny.eriksson · ‎09-13-2012

Hello,

I just configured VSS for the first time and while everything seem to have converged accordingly I seem to have issues with the standby chassis. Looking into show run I see the 2nd chassie interfaces "Gigabitethernet 2/x/y". But looking in show interfaces status, I can only see the interfaces belonging to chassie 1. Same thing when I issue show module, only chassie 1 module shows.

Same thing shows if I specify the virtual switch for each show command;

VSS-Switch#show module switch 1

Switch Number: 1 Role: Virtual Switch Active

In the logg I see no traces that the modules belonging to Switch 2 has passed any diagnostics. However the interfaces are configureable?

Very grateful for help....!

Thanks

Hi,

What is the output of "sh switch virt"?

also, can you post the vss configs?

Hi,

U need to try below

show interface status switch (switch no) module (module no#).

By default the chassis will show the info from active switch.

In addition u r missing switch mode virtual command under the vitrual domain .

Thanks

Reza Sharifi · ‎09-13-2012

Are both switches configured in SSO mode?

Also, as the Mahmood noted: add switch mode virtual command under the vitrual domain for both switches.

jhonny.eriksson · ‎09-14-2012

I can't see any "switch mode" command in virtual domain configuration mode ? All I can set are the Switch number and priority. Of course I added the "switch convert mode virtual" to both chassis before restart.

I did it all over again and verified that both chassis were indeed configured for operating with SSO.This is a Single-SUP Dual-Chassie setup. Still no modules show under the "show module switch 2".

SwitchVSS#show int status switch 1

Gi1/6/48 disabled routed auto auto 10/100/1000BaseT

Po1 notconnect routed auto auto

SwitchVSS#show int status switch 2

/// No switchports is shown...

SwitchVSS#

Interesting fact is that the VSL link (Po1) shows "not connect". However, they show active;

SwitchVSS# show switch virtual link

VSL Status : UP

VSL Uptime : 13 minutes

VSL SCP Ping : Pass

VSL ICC Ping : Pass

VSL Control Link : Te1/5/5

PS: Spelling error on the configuration. This is what I added;

Switch-1(config)# switch virtual domain 100

Switch-1(config-vs-domain)# switch 1

Switch-1(config-vs-domain)# switch 1 priority 255

Switch-1(config-vs-domain)# exit

Switch-2(config)# switch virtual domain 100

Switch-2(config-vs-domain)# switch 2

Switch-2(config-vs-domain)# switch 2 priority 100

Switch-2(config-vs-domain)# exit

I managed to solve this. It showed that I recived the supervisors with different IOS running on them. Hence only RPR mode initiated. By copying the IOS running on the active supervisor to the standby and then initiating a redundancy reload peer everything went up!

VSS-Switch#show module switch all

This is bad programming on Cisco's part but the way to see just specific module interface status on the second switch in a VSS pair is the following command.

Show interface status module (1-20). This allows enough room for 2 4510 series switches with fully loaded modules.

So lets say you want to see Module 2 on the second switch. The command would be "show interface status module 12"

I think it would have been better programmed as "show interface status switch 2 module 2"
