sh int gi 0/1 | inc erro
692945 input errors, 1 CRC, 0 frame, 692943 overrun, 0 ignored
0 output errors, 0 collisions, 0 interface resets
customer reported Intermittent dropouts and slow speed on their MPLS links
can anyone help me to troubleshoot the MPLS connection?( above attached the one of the site connected port)
I agree you have input errors of type overrun .
This means this device gi0/1 is receiving traffic with bursts that it cannot handle.
Typically this may happen on software based routers that can have gigaE interface that do not operate at line speed.
To minimize the problem, the device on the other side of the link should apply some type of output shaping to a sub rate of 1000 Mbps so that the other side can receive all the frames.
This kind of feature is available also on multilayer switch like C3560 that can set the output bandwidth to a percentage of line speed.
Hope to help
