Dear all,

we have 4 switch with 2 in VSS mode :

- 2x WS-C6509-E (in VSS)

- 2x WS-C4510R+E (in VSS)

When configuring etherchannel between them, we get the following error :

*Apr 12 03:44:44: %LINK-3-UPDOWN: Interface GigabitEthernet1/1/10, changed state to up

Thank you in advance

Hi,

Are you using a different VSS domain id for each set?

Hi Reza,

Thank you for the quick reply.

Same VSS domain :

- On C6509 VSS : domain 100

- On C4510R+E : domain 100

[Reza Sharifi · Accepted solution]

Hi,

VSS domain Ids need to be different. Something like this:

On C6509 VSS : domain 100

On C4510R+E : domain 200

Hi Reza,
I tested yesterday different VSS domain IDs and this solved the problem. Thank you very much.
Despite, Going from HSRP TO VSS seems to slow down our network, many users have trouble accessing their servers in the LAN yet VSS should make faster access than hsrp
