I have a 3640 that's running enterprise plus (c3640-js-mz.124-17.bin). The config is as follows:
interface Ethernet0/0
ip address 192.168.36.1 255.255.254.0
load-interval 30
full-duplex
!
interface Ethernet0/0.1
encapsulation dot1Q 1 native
!
interface Ethernet0/0.20
description VLAN 20- Voice VLAN
encapsulation dot1Q 20
ip address 10.0.36.1 255.255.254.0
Whenever I remove the address from e0/0 and put it on the subinterface with the native VLAN, I lose all connectivity. This router is connecting to a Dell 6248. This switch is a Layer 3 switch. Any suggestions?

The address should be on the subinterface . I would say on the dell that maybe the native vlan is not 1 and thats why you lose connectivity.

We do have this working with the same switch in a lab environment with a 2600 Router. That's why this is so confusing.

It wouldn't be any different between routers , must be something else that is different . I don't know how you configure a vlan on the dell to be nontagged .

That's what is so strange about the whole thing. In fact- we are using the same dell switch in the lab and then in the production environment. could it be something different in the code?

What I was saying as that WHEN I put the address on the subinterface, I can no longer see anything. And the Switch is in trunk mode on that port.
