Have been trying to find some recommendation for generation of Minor, Major and Critical alarms based on CRC errors on a serial port -- locIfInCRC.

Does anyone have some info regarding this? Thanks.

Users can configure the CRC threshold per interface.

Router(config)#int f0

Router(config-if)#crc threshold

"no crc threshold " will set the threshold value back to the default one.

Users can enable the trigger action:

Router(config)#int f0

Router(config-if)#crc trigger

"no crc trigger" will disable the trigger action.

Users can configure the soak time for excessive CRC error detection, the valid value is from 3 minutes to 10 minutes.

Router(config)#int f0

Router(config-if)#crc delay

"no crc delay " will set the soak value back to the default one.
