Dot1q tunneling on 4500-Sup7L-E

[michal.grzelak]

Has anyone successfully run the dot1q tunneling on Cat4500 with Sup7L-E? I tried that on IOS XE 3.3 and newest 3.4.

It is in feature navigator but i am not able to connect two access switching using trunk - only native vlan is translated. Apparently STP BPDU frames are droped somewhere.

I have the same configuration on 3750X with ip services licence and this works well.

It should work just fine, please refer to the documentation:

Yes, it should work, but it doesn't. I did the config with documentation. Moreover i have the same config on Cat3750x, Cat3560 and it works just fine. TAC is trying to resolvei the problem for 1,5 week already and still nothing.

It must be something with Cat4500 and Sup7L-E. I found some discussions on CSC from January and there were problems but new IOS XE versions were to fix it.

So, question to someone who did config on this specific platform.
