hh3cIsisAdjacencyProtocolChange

Module: HH3C-ISIS-MIB

OID (symbolic): HH3C-ISIS-MIB::hh3cIsisAdjacencyProtocolChange

OID (numeric): 1.3.6.1.4.1.25506.2.59.0.1

Node type: NOTIFICATION-TYPE

Description: A notification sent when the IPv4 or IPv6 protocol of an adjacency changes. The first 6 bytes of the isisPduLspId are the SystemID of the adjacent IS. The hh3cIsisAdjProtoType is the type of adjacency protocol. The hh3cIsisAdjProtoState is the state of adjacency protocol.

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> '' HH3C-ISIS-MIB::hh3cIsisAdjacencyProtocolChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.25506.2.59.0.1

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

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:50833->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (207195281) 23 days, 23:32:32.81
  SNMPv2-MIB::snmpTrapOID.0 = OID: HH3C-ISIS-MIB::hh3cIsisAdjacencyProtocolChange
