Switch port monitoring

[ssweehinlew]

Hi,

There are some connection issue between the server and the switch port. I would like to know whether can investigate it from the switch port level.

Apart from checking the interface status, can we enable the logging for a particular switch port? Therefore, I can know when the port when down.

How long the log can be kept inside the switch?

Hello Swee,

You can enable logging of event-status either globally or per interface, see this:

How long you can save the logs depends on how frequently switch has to log message, you can set the number of entries a switch can keep, see this:
