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> '' TPLINK-SPANNING-TREE-MIB::tpMstpTopologyChange snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.11863.6.21.2.1
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]:59608->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (504727768) 58 days, 10:01:17.68 SNMPv2-MIB::snmpTrapOID.0 = OID: TPLINK-SPANNING-TREE-MIB::tpMstpTopologyChange

Create custom SNMP monitor using the TPLINK-SPANNING-TREE-MIB::tpMstpTopologyChange OID value, configure state conditions and alerts, and monitor any TP-Link managed switch (STP/RSTP/MSTP port role/state status) from a single console.
