I have configured multiple VLANs over one network.
Core Switch to Access switch are configured with trunk to trunk connectivity using dot1q and native vlan 10.
If these switches are connected back to back with each other, everything is fine.
Now, the problem is, if the Coreswitch and Access switch are connected via E1 (2MBPS) the computers(connected to access switch) can no longer access internet and no email. Both trunk ports are experiencing collisions even if there's less than 10 users. Anyways, phones are working fine.
Taking also these users to native VLAN everything is fine.
Appreciate if anyone of you experts have encountered these kind of problem? Or do you have any suggestions on how I can resolve it?
