aal2ExternalAIS
Module: ZhoneAAL2-MIB
OID (symbolic): ZhoneAAL2-MIB::aal2ExternalAIS
OID (numeric): 1.3.6.1.4.1.5504.4.2.1.0.1
Node type: NOTIFICATION-TYPE
Description: Alarm Indication Signal - a signal, associated with a maintenance alarm detected on a defective maintenance span, that is transmitted in the direction of the defect as a substitute for the normal signal. Its purpose is to show downstream entities that a defect has been identified, so that other maintenance alarms consequent to this first defect can be inhibited. The external bit stream representation of AIS may be an all 1s signal.
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> '' ZhoneAAL2-MIB::aal2ExternalAIS snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.5504.4.2.1.0.1
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]:51831->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (304114295) 35 days, 4:45:42.95 SNMPv2-MIB::snmpTrapOID.0 = OID: ZhoneAAL2-MIB::aal2ExternalAIS
