Trunk Link Between a Cisco 2811 and a PowerConnect 5324
So I'm battling my way through a migration project involving the retiring of an old SonicWall firewall and dropping a Cisco 2811 router in its place. Currently, my uphill climb, (aside from trying to translate SonicWall's wonky rules and methods to the Cisco,) is figuring out how to create a trunk line between the Cisco 2811 and a Dell PowerConnect 5324 switch. Apparently, Dell and Cisco don't speak the same networking-lingo, they certainly don't have any handy howtos on their forums, so I'm completely screwed. Basically, here's the setup:
The Cisco 2811 has two ethernet ports, eth0/0 and eth0/1. There are two subinterfaces, eth0/1.1 and eth0/1.2, the first going to the LAN and the second going to the DMZ. In an ideal world, I'd like to simply have two VLANs on the switch, the LAN and the DMZ vlans, saving me the trouble and money of going out and getting a second switch and an additional ethernet card for the router. I did a test with a non-production Cisco Catalyst 2950, setting up the trunk-port the way we all know and love, and it was no problem communicating between the router and the switch. When I tried to figure out how to do it on the Dell, no such luck. Dell, apparently, doesn't think a port set to trunk mode is actually a trunk port. The only progress I've made is figuring out that the router is configured correctly, doing 801.Q tagging and all all that good jazz, but the Dell won't talk to it.
It's 3am where I am, the only time I can really take down the whole network without any of the developers or the CEO freaking out. While I'm thinking of calling it quits for tonight and heading to bed, I'm going to dig tomorrow and find some configs to share with y'all. I figured I'd post the issue now, however, and see if anyone knows a straightforward solution to creating a simple trunk link between a Cisco 2811 router and a Dell PowerConnect 5324 to carry two VLANs.
