macChangedNotification
Module: MY-ADDRESS-MIB
OID (symbolic): MY-ADDRESS-MIB::macChangedNotification
OID (numeric): 1.3.6.1.4.1.171.10.97.2.22.2.1
Node type: NOTIFICATION-TYPE
Description:
This notification is generated when there is enough MAC address information to fully occupy a maximum size SNMP trap message. This notification is also generated when there is at least one MAC address changed or removed and the amount of time elapsed from the previous notification is greater than the maximum wait time denoted by myMacNotificationInterval object.
If there are more MAC addresses information than can fit into one myMacNotiHisMacChangedMsg object, then multiple notifications will be generated.
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> '' MY-ADDRESS-MIB::macChangedNotification snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.171.10.97.2.22.2.1
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
