Hello all,
i have configured 4500x VSS but i found two things stange not like 6500 VSS:
1. The VSL port-channel for the primary chassis this configuration
interface Port-channel2
switchport
switchport mode trunk
switch virtual link 1
end
interface TenGigabitEthernet1/1/1
switchport mode trunk
no lldp transmit
no lldp receive
no cdp enable
channel-group 2 mode on
service-policy output VSL-Queuing-Policy
interface TenGigabitEthernet1/1/2
switchport mode trunk
no lldp transmit
no lldp receive
no cdp enable
channel-group 2 mode on
service-policy output VSL-Queuing-Policy
and the VSL port-channel for the chassis-2 as follow:
interface Port-channel3
switchport
switch virtual link 1
end
interface TenGigabitEthernet2/1/1
no lldp transmit
no lldp receive
no cdp enable
channel-group 3 mode on
service-policy output VSL-Queuing-Policy
interface TenGigabitEthernet2/1/2
no lldp transmit
no lldp receive
no cdp enable
channel-group 3 mode on
service-policy output VSL-Queuing-Policy
there is no "switchport mode trunk" available on other chassis is it normal?
2. when i do show switch virtual
show switch virtual
Executing the command on VSS member switch role = VSS Active, id = 1
Switch mode : Virtual Switch
Virtual switch domain number : 2
Local switch number : 1
Local switch operational role: Virtual Switch Active
Peer switch number : 2
Peer switch operational role : Virtual Switch Standby% Authorization failed.
what does it mean?
Thanks

Hi
Can i know what is the IOS version you are using.
For 4500-X generally can be configured with 1 VSL link as it is not a multi slotted chassis. Also VSL configuration should be pretty much striaght befor joining the switch into VSS. Please cross check the VSL configuration done. Aside ensure you dont have any other configuration pertaining to aaa.
Are you migrating the existing pair to VSS or is this a new pair. Suggest you to filter out your old configuration as per the need and do a fresh configuration post to completion vss.

Hi Steven,
Could you solve this issue? I have the same problem with IOS version 03.09.00.E. There is high CRC bir error on my VSL link. could it be the reason?
Thanks and regards,
Sam
