I'm trying to setup trunking from an ASA 5505 to a Catalyst Express CE-500.
Unfortunately, I'm confused as to what "smartport" role to use. I've tried both "switch" and "router" because I need something that turns on trunking. The problem is, the ASA will NOT send untagged traffic, so there is no native vlan (untagged). However, on the CE-500, I have to put in something for a "native vlan". Since I don't use vlan 1 for anything, I put that in as the native vlan.
This actually seems to work just fine for my tagged traffic VLANs. However, the Catalyst Express freaks out and generates an alarm light on the panel of the switch and when I read why in the gui, it says that "there is a smartport mismatch" on the port that I've got trunked to the ASA 5505.
I want to pull my hair out - everything is fine - speed and duplex match (I've got that hardcoded on both sides), and the VLANs that are active on the 5505 work to the CE500. The only thing I can assume is that it's freaking out because it's not seeing any untagged traffic?
