mstTopologyChange

OID (symbolic): PRVT-SPANNING-TREE-MIB::mstTopologyChange

OID (numeric): 1.3.6.1.4.1.738.1.5.107.0.3

Node type: NOTIFICATION-TYPE

Description: A topologyChange trap is sent by a bridge when any of its configured ports 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 newRoot 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> '' PRVT-SPANNING-TREE-MIB::mstTopologyChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.738.1.5.107.0.3

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]:63108->[192.168.30.10]:162]:
