Module: OPTIX-SONET-TRAPS-MIB

OID (symbolic): OPTIX-SONET-TRAPS-MIB::evtLossOfMultiplexSignal

OID (numeric): 1.3.6.1.4.1.2011.2.25.3.20.40.20.186

Description: Trap of Event: Loss of multiplex 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> '' OPTIX-SONET-TRAPS-MIB::evtLossOfMultiplexSignal
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2011.2.25.3.20.40.20.186

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:
