Dear Sir,
We config the vlan on 7301 router. however, it does not work. The config is following:
---
interface GigabitEthernet0/0
no ip address
ip virtual-reassembly
load-interval 30
duplex auto
speed auto
media-type rj45
no negotiation auto
hold-queue 4096 in
hold-queue 4096 out
!
interface GigabitEthernet0/0.21
encapsulation dot1Q 21 native
ip address 192.168.0.1 255.255.255.0
ip virtual-reassembly
----
following is the show inter log
