Over the last month or so we have been having some network issues as it relates to ports going down and up all by themselves. The messages are like this:
11 2147483645 27~Oct~2009 05:27:48 Info %LINK-I-Up: 1/e22
12 2147483646 27~Oct~2009 05:27:46 Warning %LINK-W-Down: 1/e22
This will continue randomly and the ports stay only down for about 2 seconds as you can see above. I have started over on the configuration by loading defaults and still no luck. Users have been reporting that their computers are loosing link every once in awhile. I have two 3548P switches in a stack and both switches have this occur. Any ideas what would be causing this? Does the configuration file look ok below? Thank you for anyone's help!
