linkChangeEvent
Module: ES1000-MIB
OID (symbolic): ES1000-MIB::linkChangeEvent
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.1.1.0.2
Node type: NOTIFICATION-TYPE
Description: The trap is sent whenever the link state of a port changes from link up to link down or from link down to link up
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> '' ES1000-MIB::linkChangeEvent snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.326.2.20.1.2.1.1.0.2
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]:50360->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (136268472) 15 days, 18:31:24.72 SNMPv2-MIB::snmpTrapOID.0 = OID: ES1000-MIB::linkChangeEvent
