svcEndPointMacLimitAlarmRaised
Module: TIMETRA-SERV-MIB
OID (symbolic): TIMETRA-SERV-MIB::svcEndPointMacLimitAlarmRaised
OID (numeric): 1.3.6.1.4.1.6527.3.1.3.4.2.0.18
Node type: NOTIFICATION-TYPE
Description:
The svcEndPointMacLimitAlarmRaised notification is sent whenever the number of MAC addresses stored in the FDB for this endpoint exceeds the watermark specified by the object svcTlsFdbTableFullHighWatermark.
This alarm also takes into consideration static MAC addresses configured on the endpoint and learned MAC addresses in all spokes associated with this endpoint.
What is svcEndPointMacLimitAlarmRaised?
This SNMP notification (trap) is sent when the total number of MAC addresses (learned plus static) in a service endpoint's FDB reaches the high-water mark configured in the svcTlsFdbTableFullHighWatermark object. The alarm indicates potential MAC table exhaustion on that endpoint. An operator receives this trap to investigate possible MAC flooding attacks, misconfigured devices, or the need to increase MAC table capacity.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' TIMETRA-SERV-MIB::svcEndPointMacLimitAlarmRaised snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6527.3.1.3.4.2.0.18
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
