Hello,
We have two 6500 & are trying to create VSS for this.
Below are the configurations on both switches;
Switch1:-
switch virtual domain 100
switch mode virtual
switch 1 priority 110
interface Port-channel1
description VSL to Switch2
no switchport
no ip address
no platform qos channel-consistency
switch virtual link 1
interface TenGigabitEthernet1/5/4
no switchport
no ip address
no cdp enable
channel-group 1 mode on
!
interface TenGigabitEthernet1/5/5
no switchport
no ip address
no cdp enable
channel-group 1 mode on
sh switch virtual
Switch mode : Virtual Switch
Virtual switch domain number : 100
Local switch number : 1
Local switch operational role: Virtual Switch Active
sh switch virtual link port-channel
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use N - not in use, no aggregation
f - failed to allocate aggregator
M - not in use, no aggregation due to minimum links not met
m - not in use, port not aggregated due to minimum links not met
u - unsuitable for bundling
d - default port
w - waiting to be aggregated
Group Port-channel Protocol Ports

1 Po1(RD) - Te1/5/4(D) Te1/5/5(D)
=============================================================
Switch2:-
switch virtual domain 100
switch mode virtual
switch 1 priority 110
interface Port-channel2
description VSL to switch2
no switchport
no ip address
no platform qos channel-consistency
switch virtual link 2
interface TenGigabitEthernet2/5/4
no switchport
no ip address
no cdp enable
channel-group 2 mode on
!
interface TenGigabitEthernet2/5/5
no switchport
no ip address
no cdp enable
channel-group 2 mode on
Te5/4 on switch 1 is physically connected to Te5/4 on switch2.
Appreciate all help.

Once VSS is working the individual ports line te3/4 would be 1/3/4 1 for switch 1 3 for blade 3 and 4 is the port.
also on switch 2 the same port will be 2/3/4 2 for switch 2 3 for blade 3 and 4 is the port.
Also, follow the config guide to make sure the VSS working:

We are looking to do VSS with only one link between both switches.
is it different from the above?

There is no difference. You can use one link or 2 links, but for redundancy it is always a good idea to use 2 links. Also, you don't need this command on either switches:
switch 1 priority 110
Also, you did not explain the issue you have.

sorry, i guess forgot to type the complete thing.
We are trying to run VSS on two 6500's with single link between them.
i have used the configuration above, but the VSS doesn't come up.
doing a sh virtual switch only shows the current switch ; i.e switch 1
If we are using single link , on each individual port like te3/4 how would the configuration look like, as i see the switch virtual link command is used under Port channel.
please help in this.
