I have a 1921 Router with two gig interfaces but only one of them seems to work.
Both of them are connected to a 3750 switch with the same config on both ports. I have tried different cables but no difference. I had a look on the command show controllers for the interfaces and found this
lon-er01#show controllers gig0/0 | i Port Port Stopped: Y lon-er01#show controllers gig0/1 | i Port Port Stopped: N
The configuration interface GigabitEthernet0/0 description mgmt ip address 172.24.55.9 255.255.255.0 duplex auto speed auto ! interface GigabitEthernet0/1 ip address 10.150.0.1 255.255.255.0 duplex auto speed auto end
lon-er01#show ip inter brief Interface IP-Address OK? Method Status Protocol GigabitEthernet0/0 172.24.55.9 YES NVRAM down down GigabitEthernet0/1 10.150.0.1 YES NVRAM up up
- Swap the cables between gig0/0 and gig0/1. Gig0/1 was previously up and working so it is a known good link. If you plug that link into gig0/0 and gig0/0 comes up then obviously there is no issue with gig0/0.
