I have a 3845 router with 2 4 port ESW modules. I've configured virtual vlan interfaces and put the physical switch port int's in their respective VLAN. However, I cannot get layer 3 traffic to forward out any of the switch ports.
I have a 2800 configured the same way and it works fine. Is there something different in the 3800 architecture for this to work differently?
I run a debug IP packet, I get encapsulation failed or unroutable. On the other hand, the arp table populates the IP I'm trying to reach with the correct MAC. The routing table on the router shows my interface as connected as well. Plus,I just upgraded the router to the latest Enterprise IOS.
The built in Fast Ethernet interfaces route layer 3 traffic just fine; so it's something with the interaction of IOS and the 4 port switch modules for routing layer 3 traffic. I'm at a loss!
