We have two switches that do not seem to be passing VLAN traffic. The two switches are a Dell Powerconnect 5324& a Cisco 3560G. The Cisco switch appears to be functioning fine, but the Dell switch is only passing traffic to the Cisco that is on the default untagged VLAN1. Our second VLAN is not getting passed to the Cisco at all, I am not seeing any packets tagged with the particular vlan in Wireshark. I have Port 1 on the Dell switch connected to port 29 on the Cisco switch, and port 1 on the Cisco switch connected to the ASA. I have the following config on the relevant ports on the Cisco switch:

Anyone have any ideas or pointers? Is there more information that I need to provide? Vlan1 works just fine, of course. It is Vlan 12 that is not working. Everything on the Dell switch is communicating with each other just fine on the same subnet.
I can confirm similar issues between our older Dell Poweredge 1655 and a Cisco 3550. Took me a while to figure this one out, considering the aggro trunks weren't working right either. Switching it to etherchannel solved the trunking issue, but I still had some major issues with VLANs even after that.
I have yet to move the 1655 (since we still use it for lab purposes) to the 6503.
I hate to put it this way, but I'd love to know what crack Dell was doing when they decided to use the software/hardware switch stuff they did.
