What is hwMstpiStpRXTCNBPDU?
Counts Topology Change Notification BPDUs received on this port. A rising count reflects how often the connected segment is reporting topology changes, which can indicate a flapping link somewhere downstream.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.42.4.1.20.1.15 snmpwalk -v2c -c public <target> HUAWEI-IPDSLAM-MSTP-MIB::hwMstpiStpRXTCNBPDU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2011.5.25.42.4.1.20.1.15.1 snmpget -v2c -c public <target> HUAWEI-IPDSLAM-MSTP-MIB::hwMstpiStpRXTCNBPDU.1
