lerAlarmOn

Module: CISCO-STACK-MIB

OID (symbolic): CISCO-STACK-MIB::lerAlarmOn

OID (numeric): 1.3.6.1.4.1.9.5.0.1

Node type: NOTIFICATION-TYPE

Description: A lerAlarmOn trap signifies that the agent entity has detected that the fddimibPORTLerFlag object in the FDDI-SMT73-MIB (RFC 1512) has transitioned to the true(1) state for one of its ports. The generation of this trap can be controlled by the fddimibPORTLerAlarm object in the FDDI-SMT73-MIB for each port.

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> '' CISCO-STACK-MIB::lerAlarmOn
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.5.0.1

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]:57280->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (304470976) 35 days, 5:45:09.76
