Catalyst 6500 Sup720-10G VSS VLAN Translation & Port-Channels?

[andrew.butterworth]

As part of a migration plan I need to translate a VLAN on a multi-chassis port-channel on a pair of C6500 Sup720-10G VSS switches.

I have two layer-2 port-channels configured for LACP on some WS-X6708-10G linecards:

PC10 = Te1/6/1 & Te2/6/1

PC20 = Te1/6/2 & Te2/6/2

There are a few VLANs allowed on these trunks and STP is blocking on one of them.  Due to a clash I need to translate VLAN 10 on the C6500 side to VLAN 110.  I have verified it's possible in the IOS we are running and the WS-X6708-10G linecards,  and I can see the commands are available, however I can't specifically find references to doing this with port-channels or VSS.

Can anyone confirm this is possible?

what is the version of code both the sides :

check some reference : (more focus on -Table 23-2 Module Support for VLAN Translation)

Yes, that's the link I am looking at.  Its a VSS pair so the IOS is identical on each - IOS is 12.2(33)SXI3 which is supported.  The switch it will connect to is a C9500 series, however there are no changes required on the C9500 side.

The commands are available so its obviously supported in the code and according to the link the WS-X6708-10G module will work without any restrictions other than a maximum of 16 translation as its an ASIC per port.

I just want to verify I can do this on port-channels split over two VSS chassis on WS-X6708-10G linecards.  The examples on that page you linked to only reference physical interfaces and not port-channels and also it doesn't mention VSS.

 WS-X6708-10G 

This may not running 12.X  code IOS right, that should 15.X  code since its latest one.

Honestly have not fully tested, this should work as expected technically, since this is just translation of VLAN.

Unfortunately upgrading the code isn't an option.

The WS-X6708-10G linecards are supported in 12.2(33)SXI3 as they are currently in use.  I am purely asking about the VLAN translation feature when related to VSS & port-channels.
