2621 Router running 12.3(6)
I recieved a warning from my monitoring application that one of my serial interfaces was down for more than 5 minutes. My (buffered) logging is set to warnings (@ 20MB) but in the time period the interface was supposedly down I show nothing.
The only thing the sh log provides is a few UPDOWN state changed to UP overnight.
So how can I show the line UPDOWN notices stating UP without any corresponding UPDOWN notices stating the interface went down?
