I upgraded one of my old 3500 switches to a 4948. The log on the 4948 doesn't show port events like up/down events. All I see in the log is configuration changed events.
Is there a way to turn this on?
I have this in the config.
logging buffered 65536 debugging
logging trap debugging
logging source-interface Vlan1
Just follow Jon's advice and use the interface range command and apply " logging event link-status" to all your ports .
My switch won't take that command.
itsw-4948(config)#logging event link-status global

Apologies, the command was introduced in IOS version 12.2(25)SG so you would need to upgrade to have it available.
