Question : Cisco VLAN trunk ASA5510 to Catalyst 3550.

I am working on a project where an ASA5510 needs to be configured with multiple VLANs on a single physical interface. This has been configured using the sub interfaces with no issue. The port is then being connected to a Catalyst 3550. The switchport on the 3550 has been set to trunk mode using dot1q encapsulation. For some reason I cannot get any traffic to pass between the devices over any VLAN.

Any help is appreciated.

Answer : Cisco VLAN trunk ASA5510 to Catalyst 3550.

Well after a few different attempts at getting this to work, I realized that it may be an issue with the IOS version. After upgrading the IOS on the Catalyst 3550 to a new version the original configuration worked like a charm. Originally the IOS was an older version of the 12.1 tree, the updated version I moved to was a newer version in the 12.2 tree.

Thanks for the help and suggestions.
