on the port add "snmp trap link status" .

[kwanm63]

already tried that.

I'm tried adding

snmp-server enable traps snmp authentication linkdown linkup warmstart

but don't see any messages even when I do a 'show logging"

[glen.grant]

Your logging buffered statement may be too low , try logging buffered informational .

Actually, notifications should log interface up/down messages as they are severity 5 messages and you should be OK there. Is the switch just not logging link-up/down messages or it doesn't log anything at all?

I've already have the following.

logging buffered informational

logging console informational

logging monitor informational

sh logg just give this lone message that repeats every hour

Apply the following to each interface you would like UPDOWN messages generated for:

logging event link-status

[kwanm63]

logging event link did the trick.

thanks all for the help.
