What is mstpPortTxTcnBpduCounter?
This read-only counter tracks how many Topology Change Notification (TCN) BPDUs this port has transmitted. A steadily climbing value can indicate this port itself is the source of repeated topology-change events, worth investigating for a flapping link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6027.20.2.11.1.19 snmpwalk -v2c -c public <target> FORCE10-MSTP-MIB::mstpPortTxTcnBpduCounter
