atmAceAlarmVcGCRAViolation
Module: RAD-MIB
OID (symbolic): RAD-MIB::atmAceAlarmVcGCRAViolation
OID (numeric): 1.3.6.1.4.1.164.6.1.12.0.65
Node type: NOTIFICATION-TYPE
Description: This trap indicates GCRA violation on a VC Connection reported by UPC device.
What is atmAceAlarmVcGCRAViolation?
This SNMP trap is sent when a Generic Circuit Rate Algorithm (GCRA) traffic contract violation is detected on an ATM virtual connection, as reported by the Usage Parameter Control (UPC) enforcement device. GCRA violations indicate that a sender is exceeding the negotiated traffic contract (cell rate or burst size), which can cause network congestion or service degradation. Network operators receive this notification to alert them of potential misconfigurations or abuse.
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> '' RAD-MIB::atmAceAlarmVcGCRAViolation snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.164.6.1.12.0.65
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
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:63021->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (148283437) 17 days, 3:53:54.37 SNMPv2-MIB::snmpTrapOID.0 = OID: RAD-MIB::atmAceAlarmVcGCRAViolation
