RE: VSS Strange Problem

A bug this big would get that code deferred. You could do wr erase on them to
clear up the config and walk through it again. Other than that you could open
a case with tac - this most certainly is for your work and off topic. Travis

Dear Gents,

Regarding the VSS problem i mentioned, did anyone test it with the IOS
version 12.2(33)SXI1?Shall I go for an upgrade?
Note that the original problem was as follows:

I am new to VSS however I am facing a strange problem. I configured the 2
Core switches to be running in VSS mode. When using the show switch virtual
role both switches show with one of the switches as ACTIVE and the other as
Standby. However on the standby switch the fiber Gigabit module displays
ORANGE LED, thus no ports on the STANDBY switch are operating except the
TenGig ports which are used for the VSL Link. One more thing that makes the
problem look even more strange is that when I shutdown the primary switch
the STANDBY switch module goes active (GREEN) and operates properly. When
the primary switch comes UP again, both switches appear as ACTIVE ACTIVE.
The configuration I used is relatively sample:

SW1

switch virtual domain 10
switch 1 priority 200
switch 2 priority 100
switch 1
mac-address use virtual
exit

int port-channel 1
switch virtual link 1
no sh
exit

int range tengig5/4-5
channel-group 1 mode on
no sh
exit

switch convert mode virtual

SW2
switch virtual domain 10
switch 1 priority 200
switch 2 priority 100
switch 2
mac-address use virtual

int port-channel 2
switch virtual link 2
no sh
exit

int range tengig5/4-5
channel-group 2 mode on
no sh
exit

switch convert mode virtual

 One more thing which i noticed is that there is the command switch accept
mode virtual which copies the VSL configuration from the standby chassis to
the active chassis. I missed this command when doing the configuration?

Any help will be much appreciated!
