Link Up and Down
Hi was looking in my RAM Log on one of the 3448 switches and noticed several links going from up to down and back up status. An example is below:
%LINK-W-Down: E37
%LINK-I-Up: E37
%LINK-W-Down: E37
Is this normal?

Hi
Thanks for your post, I am also experiencing the same issue with my 5424 switch, I have 2 switches, connected to Dell equallogic SAN . I lose connectivity often with one of the switch and all connectivity to san is lost. I see the errors in the log (one of the port up and down). I just wonder, if i agree this ports is faulty, it will stop the entire switche's connectivity?!
Lately, if you could find a solution, kindly share with me.
Thank you

Please post your configuration, description of your network, log file output.
Links going up and down are often HW issues. To debug, One at a time in this order:, change ports, change cables, change transceivers,change switch.
