When a buffer usage threshold has exceeded its configured percentage, a message is logged, and optionally, an SNMP notification is sent to all configured destinations.
Use the following command to configure the notification that is sent when the buffer usage has exceeded the configured threshold:
(config) # snmp-server notify event bufferoverusage
The SNMP notification will be sent when a threshold is exceeded in any 5-second interval. Once the notification is sent, there is a 30 second holdoff time before the notification is sent again.
