I believe the even with the native command configured under the ethernet
10mbps interface, i couldn't get it to work as well.
I'm not sure if it has something to do with the order of operation. I could
have it working w/o any problems if it was a Fastethernet on a 2600XM.
On R6:
Interface Ethernet0/0.263
encapsulation dot1q 263 native
ip address 204.12.1.6 255.255.255.0
!
On SW1:
interface FastEthernet0/6
switchport trunk encapsulation dot1q
switchport trunk native vlan 263
switchport trunk allowed vlan 6,263
switchport mode trunk
end
!
I mean, there has to be something with the native vlan when it is configured
on an ethernet interface, as my understanding was all this while that
ethernet interface can't support the native vlan.
Appreciate really if someone could correct me if i'm wrong.
Thanks.
