Port Stopped: Y

Hi,

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

Any idea why it says "Port Stopped: Y"?

Thanks for your help

- Swap the cables between

- 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.
