4500X + VSS + VLAN mapping = crash ?

Hello

We are deploying two 4500X in VSS.

We need to perform vlan mapping between two layer2 parts of the campus.

As soon as we bring up the trunk between the 4500X and the old network, the 4500X crashes.

If we remove the vlan mapping config, then no problem bringing up the trunk.

Below is an extract of the console log (the trunk is on the standby unit)

I am opening a TAC case right now, but wanted to ask here if anybody has experienced the same issue, or has any other idea ?

crash happens bith both versions:

cat4500e-universalk9.SPA.03.04.01.SG.151-2.SG1.bin

cat4500e-universalk9.SPA.03.05.00.E.152-1.E.bin

4500x-standby>

VLAN mapping is not supported on VSS. Please see the following part of

the configuration guide:
