I am trying to determine a problem with flapping interface on a router not showing up in log buffer if Cisco IOS. I've included the config on the switch that pertains to the logging and can't seem to figure what is going on. The SNMP trap is being sent to our Central Management trap server and that is reporting the interface flapping but the flap doesn't show up in the log messages. Any ideas?
