All sorted. It was a spanning tree issue
Hi all I am facing a very unusal problem. I have created three vlan (10,20 and 200) on dell powerconnect 6224 and pcm6348. vlan 20 and 200 are working fine and passing traffic between the switches. somehow vlan 10 is not passing traffic between the switches at all although it is configured and connected in exactly the same manner as of vlan 20. can you please l ook at the running configs of both switches and see if I am made any silly mistanke. If you need any further details then please let me know.
