just wondering if anyone has come across the error before?
The interface is connected to a Adva 150 (BT EAD NTE) which is not showing up according to BT who are looking at the NTE.
This error occurs when I ammend the speed/duplex of the Cisco router, but not come across this in the past.
Below is the config as seen on fa0/1:-
no ip address
no ip redirects
description MONITORED-INTERFACE BT ETHXXXXXX
encapsulation dot1Q 3034
ip address x.x.x.x x.x.x.x
The IOS version running is 12.4 (25b).
Any advice or help on this would be much appreciated.
