L2 xconnect send packet as received to the other interface without any
modification. So the behavior you observed is correct. If you want to perform
VLAN tag translation to match the sub-interface, put an interface tag-rewrite
pop operation on both sub-interfaces. It will then pop the VLAN tag on input
and push the correct VLAN tag on output. This is the CLI:
DBGvpp# set interface l2 tag-rewrite ?
set interface l2 tag-rewrite set interface l2 tag-rewrite
<interface> [disable | pop {1|2} | push {dot1q|dot1ad} <tag> <tag>]

Subject: [vpp-dev] L2 Xconnect does not re-write vlan tags?
Hi,
I have a L2 cross-connect configuration where packets arrive on a sub-if1 (with
vlan id 500) and go out on sub-if2 (with a vlan stack 200, 150).
When I send packets on sub-if1, it is getting out on sub-if2, but the vlan tags
are not getting re-written. Is there anything else that should be done or is
this the standard behavior?
Thanks,
-nagp
