I do have two switch modules on all 4x3725 routers. I am using the first
module for access ports and the second for trunking to other switches. I did
not know that you are unable to have two switch modules on the same 3725.
Bellow are the relevant configs...
Thanks for your help ...
Basically everything looks ok and here is the relevant output ...

Are you sure you dont have multiple switch modules in one router ?
YOU SHOULD NOT have multiple switch modules in one given router .

Hi there,
I am having a problem with dynamics. Specifically I am not able to trunk
between two swithes (3725). Although the link shows as a trunk(dot1q hardcoded)
and I am able to assign ports to the correct VLANS I am not able to ping from
one router to another across the two switches (vlans are going across according
to the output). Any ideas guys?
Thanks very much
Yiannis
