Support for PAgP and LACP over dot1q tunnel

[ns]

Hi,

I've tried to configure a Etherchannel over a dot1q tunnel using the protocols PAgP and LACP and it doesn't work, the channel worked only when put in the "on" mode eg not using PAgP nor LACP. Which indicates that they are not supported on a dot1q tunnel. Is this correct that they are not supported? Will they be suppported in the future?

Thanks,

Niels

Yes, You are right, it's not supported at present. Possibly a bug and might be implemented in future release.

I just configured LACP over a tunnel and used SPAN to capture the LACP packets entering the tunnel. See the config below.
The key is "l2protocol-tunnel point-to-point lacp" to allow lacp through.


interface FastEthernet0/21
>  switchport access vlan 201
>  switchport trunk encapsulation dot1q
>  switchport mode dot1q-tunnel
>  l2protocol-tunnel cdp
>  l2protocol-tunnel stp
>  l2protocol-tunnel point-to-point lacp
>  no cdp enable

Hi all,

I have a Catalyst 4507 with SUP7L-E running cat4500e-universalk9.SPA.03.03.00.SG.151-1.SG.bin.

The network diagram is attached.

I'm trying to transport PAgP over dot1q tunnel but PAgP packets are not carried from one site to the other on any direction.

The configuration on 4500 interfaces is:

interface GigabitEthernetx/y

switchport access vlan X

switchport mode dot1q-tunnel

l2protocol-tunnel cdp

l2protocol-tunnel lldp

l2protocol-tunnel stp

l2protocol-tunnel vtp

!

I cannot find the command 'l2protocol-tunnel point-to-point pagp'. Is it supported?

I did the same test with LACP but it didn't work.

Can you help me?

Regards

Stefano
