hi eveyone,
We are facing the problem for the past few days .In our company network we have a L-3 at third floor and a switch connected with a
backbone cable in the seventh floor . whenever the switch in seventh floor is booted it works as normal but after 5-10 minutes the
switch becomes out of network . We have changed our backbone cable but the same condition still persist .when i checked the
port through which the backbone is connected it gives the CRC error.
Can anyone tell why this happens ?
