Are VLANs supported on Ethernet (10Mbps) ports? If so, I can't get mine to work. I am connecting a Catalyst4006-S2 with a Cisco4500-M running CatOS 7.4.3 and 12.1.21 IP+ respectively. Both of the software versions supposedly support 802.1q trunking.
====================================
The switch looks like this:
set vlan 2 name V2
set vlan 21 name V21
set trunk 2/4 nonegotiate dot1q !TRUNK UNCONDITIONALLY
clear trunk 2/4 1 !CLEARS VLAN 1 FROM TRUNK PORT
====================================
The router looks like this:
ip routing
interface Ethernet1
no ip address ip address 10.10.0.1 255.255.255.0
no ip redirects
no ip mroute-cache
media-type 10BaseT
no shutdown
interface Ethernet1.2
encapsulation dot1q 2
ip address 10.10.0.1 255.255.255.0
no shutdown
interface Ethernet1.21
encapsulation dot1q 21
ip address 10.0.21.1 255.255.255.0
no shutdown
====================================
Any help would be greatly appreciated. Thanks, Tim

Trunking is not supported in 10Mbps Ethernet interfaces on the 4000 series routers. You need the NP-1FE interface to do trunking (ISL only). The Cat4000 sup2 system only supports dot1q, so you'll need either a different router or a different switch to trunk with. An alternative if you only have 2 vlans is to use two 10BaseT ports on the router (one for each vlan).

I was afraid someone was going to tell me this. I wish that we were only using 2 subnets, but I need 3. I was thinking about purchasing the old NP-6E if they won't purchase a new router. Thanks, Tim
