linkDown
Module: NETSTAR-MIB
OID (symbolic): NETSTAR-MIB::linkDown
OID (numeric): 1.3.6.1.2.1.11.0.2
Node type: NOTIFICATION-TYPE
Description: A linkDown trap signifies that the sending protocol entity recognizes a failure in one of the communication links represented in the agent's configuration.
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> '' NETSTAR-MIB::linkDown snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.11.0.2
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]:60662->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (295898358) 34 days, 5:56:23.58 SNMPv2-MIB::snmpTrapOID.0 = OID: NETSTAR-MIB::linkDown
