rcMstpTopologyChange

Module: SWITCH-MSTP-MIB

OID (symbolic): SWITCH-MSTP-MIB::rcMstpTopologyChange

OID (numeric): 1.3.6.1.4.1.8886.6.1.24.1.3

Node type: NOTIFICATION-TYPE

Description: A rcMstpTopologyChange trap is sent by a bridge when any of its configured ports in any instance (CIST or MSTI) transits from Learning state to Forwarding state, or from Forwarding state to Blocking state.

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> '' SWITCH-MSTP-MIB::rcMstpTopologyChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.8886.6.1.24.1.3

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]:50695->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (315546631) 36 days, 12:31:06.31
  SNMPv2-MIB::snmpTrapOID.0 = OID: SWITCH-MSTP-MIB::rcMstpTopologyChange
