MDS 9509 - Mgmt Interface alerts

Unanswered Question
Feb 6th, 2007

I am seeing the following entries in the logs for my MDS 9509 :

2007 Feb 7 01:48:03 PORT 5 IF_UP Interface mgmt0 on slot 5 is up

There are no other entries in the log that the mgmt0 interface went down so why would alerts say that it is "up" ?

I have this problem too.

Failover. More than likely sup6 had been the primary up until this point. The supervisor failed over for an upgrade or for some reason.

There are no indications in the log that supervisor failover ocurred. Also, there are no alerts that say the primary sup went down only that it is "up".

Looks like the mgmt interface has been bouncing up & down since Sept. What is this attached to? What does that log say? Is the duplex and speed the same on both sides? Can you replace the cable? Does the show interface mgmt 0 show increasing CRC and/or output errors? These are the things to look for. Try a new cable as it's the easiest and most probable issue.
