As per the document at
it appears that we must put the
"logging event link-status" command on every interface if we wish to see any link down/up message in the log buffer.
Do we need to put this command only if we wish to see link down/up messages at boot time. What about if we want to see link down/up messages during normal operartion? Do we still need to put this command. What is the default behaviour?
We have a CAT 6500 where we are not seeing link down/up messages in the log.
Another symptom is that on this CAT 6500 even when the interface has been down for over 5 minutes, it shows the 5 minute load as 46 or 48 Megabits received and transmitted and this doesn't make sense.
