Changing the Circuit State

[campyracr]

I have an ARN...a few actually.

One was working for a while. Today it started acting flaking, not passgin DHCP requests etc. Then when I connected with the console cable & Typed sho ip cir it showed:
[1:1]$ sho ip cir
Circuit Circuit # State IP Address Mask
-------- ----------- -------- ---------------- ----------------
E01T 1 Up xxx.xx.xx.xxx 255.255.255.0
E01B 2 Down xxx.xxx.xx.x 255.255.255.0

I thought it was the config, so I reverted to a backup copy, and then to an alternate config all together. same result. Circuit 2 appears "down"

I even changed the router & booted into various configs with the same result.

So, it isn't the hardware, It could be the config but I am doubtful as they all shouldn't be corrupt. Could it be the card they are saved on?

The circuit will show down if the is not a valid ethernet connection. Simple question. Check cable? You said you swapped the router. Plug in a known switch/hub and cable and see if it comes up.

I swapped the cables as well. That is the cable from circuit 1 into 2 and visa versa. It appeared to be up then but as soon as I switched it back it died again.

Try checking the port configuration on whatever the two ethernet interfaces are plugged into , i.e port speeds,
