VSS - working but how ?

Hi

I have just configured VSS between 2 6504 cisco switches.

I have enabled the vss as such -

switch virtual domain 4
switch mode virtual
switch 1 priority 255
mac-address use-virtual

The other switch was switch 2 priority 1.

On the port-channel which is set to 254 for both switches -

interface Port-channel254
description VSL-Etherchannel
no switchport
no ip address
switch virtual link 1
mls qos trust cos
no mls qos channel-consistency

Thats on switch 1 on switch 2 it set it for switch virtual link 2.

Funny thing is when i look at sh int status for the tengig links i am using for this  it shows notconnect.

On the sh ip int brief the interfaces show up and down

Yet the VSS appears to be working because when i do the following -

sh switch virtual -- i get

Switch mode                  : Virtual Switch
Virtual switch domain number : 4
Local switch number          : 1
Local switch operational role: Virtual Switch Active
Peer switch number           : 2
Peer switch operational role : Virtual Switch Standby

And if i do - sh switch virtual troubleshooting

                            Peer Peer          Peer   Peer      Timer(s)running
Interface Flag State        Flag MAC           Switch Interface (Time remaining)
--------------------------------------------------------------------------------
Te1/1/5   vfsp operational  vfsp c471.fe31.c740 2      Te2/1/4   T4(616ms)
                                                                 T5(29.93s)
Te1/1/4   vfsp operational  vfsp c471.fe31.c740 2      Te2/1/5   T4(616ms)
                                                                 T5(29.93s)

Switch  Group        Number         Oper(Conf) Oper(Conf)         SID     SID
--------------------------------------------------------------------------------
Local   0      TRUE    1     UP       N (N )     255(255)  ACTIVE   0       0  
Remote  1      TRUE    2     UP       N (N )     1  (1  )  STANDBY  5830    6913

Finally

sh switch virtual link

Oxford6504-1#sh switch virtual link
VSL Status : UP
VSL Uptime : 1 hour, 32 minutes
VSL SCP Ping : Pass
VSL ICC Ping : Pass
VSL Control Link : Te1/1/4

And obviously i can see all the interfaces on the master switch and cannot connect to the sup on the standby switch

Have i a problem or is this normal and should i ignore the sh int status and sh ip int brief.

Many thanks

Steve

Why would you connect on the standby supervisor ?

The active one controls all the line cards, has control on both chassis and controls all layer 2 and 3 traffic.

the console in the standby supervisor is disabled
