isisMaxAreaAddressesMismatch

Module: ISIS-MIB

OID (symbolic): ISIS-MIB::isisMaxAreaAddressesMismatch

OID (numeric): 1.3.6.1.2.1.138.0.6

Node type: NOTIFICATION-TYPE

Description: A notification sent when we receive a PDU with a different value for the Maximum Area Addresses. This notification includes the header of the packet, which may help a network manager identify the source of the confusion.

The agent must throttle the generation of consecutive isisMaxAreaAddressesMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time.

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> '' ISIS-MIB::isisMaxAreaAddressesMismatch
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.138.0.6

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]:56243->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (335779763) 38 days, 20:43:17.63
