I did the following config for VSS:
Core 1:
switch virtual domain 1
switch 1
switch 1 priority 110
switch 2 priority 100
interface port-channel 71
switch virtual link 1 no shut
interface range tenGigabitEthernet 5/4 – 5
channel-group 177 mode on
no shut
Core 2:
switch virtual domain 1
switch 2
switch 1 priority 110
switch 2 priority 100
interface port-channel 72
switch virtual link 1
no shut
interface range tenGigabitEthernet 5/4 – 5
channel-group 177 mode on
no shut
When i put the following on both core switches:
switch convert mode virtual
they got restarted and on Core 1 i got this message:
Jun 29 01:25:30.363: %PFREDUN-6-ACTIVE: Initializing as ACTIVE processor for this switch
*Jun 29 01:25:31.107: %VSLP-5-RRP_NO_PEER: No VSLP peer found. Resolving role as Active
*Jun 29 01:25:31.739: %VSLP-2-VSL_DOWN: VSL links down and not ready for any traffic
*Jun 29 01:25:32.743: %OIR-SW1_SP-6-CONSOLE: Changing console ownership to route processor
Both the core switches interfaces got re-numbered but they did not become VSS and were working as independent. What could be the problem?
After reboot the port-channel 177 was up also.
Even i put this command "switch accept mode virtual" but no luck.

Dear, Since it was a live environment i had to roll it back to normal mode, however i remember doing "show redundancy" and it was showing me only one active processor. Dont remember if it was showing Simplex mode or not? But incase if it does show Simplex mode even after VSS configuration what does that mean? And what else could have gone wrong? Thanks, Aamir

if it showes simplex mode then please configure like this:
Core 1:
switch virtual domain 1
switch 1
switch 1 priority 110
mac-address use-virtual
interface port-channel 71
switch virtual link 1
no shut
interface range tenGigabitEthernet 5/4 – 5
channel-group 71 mode on
no shut
Core 2:
Redundancy
mode sso
switch virtual domain 1
switch 2
switch 2 priority 100
mac-address use-virtual
interface port-channel 72
switch virtual link 2
no shut
interface range tenGigabitEthernet 5/4 – 5
channel-group 72 mode on
no shut
just check if the port channel group is right or not ......
Regards
Please rate if it helps.

Dear, yes i also realize that port channel number should be same under the TenGig interface, i guess i made a type error. Also i need to ask in a state where the port channel was configured wrong and switches are in VSS state that is their interface are re-numbered, would changing the port channel and restarting the switches solve the problem or i would have to first convert them in stand alone mode and then do VSS config all over again? Thanks, Aamir

Hi xSHANT,
Change the port channel and other config as above and restart the switch..it shouold solve the problem.
if not then ...you have to beign with scratch.

Hi,
check below configuration
sw1(config)#redundancy
sw1(config-red)#mode sso
sw2(config)#redundancy
sw2(config-red)#mode sso
sw1(config)#switch virtual domain 100
sw1(config-vs-domain)#switch 1
sw1(config-vs-domain)#exit
sw2(config)#switch virtual domain 100
sw2(config-vs-domain)#switch 2
sw2(config-vs-domain)#exit
Sw1(config)#interface port-channel 10
Sw1(config-if)#switch virtual link 1
Sw1(config-if)#no shut
Sw2(config)#interface port-channel 20
Sw2(config-if)#switch virtual link 2
Sw2(config-if)#no shut
sw1(config)#interface range ten 3/1-2
sw1(config-if)#channel-group 10 mode on
sw1(config-if)#no shu
sw2(config)#interface range ten 3/1-2
sw2(config-if)#channel-group 20 mode on
sw2(config-if)#no shu
Sw1#switch convert mode virtual
Sw2#switch convert mode virtual
To verify,
show switch virtual
show switch virtual link
shwo switch virtual role

Check the Port-channel Number is not same on both the side, if it's same I would suggest to have different number on both the side and reboot the device, I hope that will solve issue.
