mstpTopologyChange
Module: FORCE10-MSTP-MIB
OID (symbolic): FORCE10-MSTP-MIB::mstpTopologyChange
OID (numeric): 1.3.6.1.4.1.6027.20.2.0.3
Node type: NOTIFICATION-TYPE
Description: A mstpTopologyChange trap is sent by a bridge when any of its configured ports n any instance (CIST or MSTI) transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a mstpNewRootBridge trap is sent for the same transition. Implementation of this trap is optional.
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> '' FORCE10-MSTP-MIB::mstpTopologyChange snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6027.20.2.0.3
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]:65437->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (18601885) 2 days, 3:40:18.85 SNMPv2-MIB::snmpTrapOID.0 = OID: FORCE10-MSTP-MIB::mstpTopologyChange
