tnXstpPortStatsTcnTx
Module: TN-XSTP-MIB
OID (symbolic): TN-XSTP-MIB::tnXstpPortStatsTcnTx
OID (numeric): 1.3.6.1.4.1.868.2.5.111.2.5.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The number of TCN Configuration BPDU's transmitted on the port.
What is tnXstpPortStatsTcnTx?
Count of Topology Change Notification BPDUs transmitted on this port. A rising count suggests frequent topology changes (link flaps, MAC moves) are being propagated from this port — worth investigating for a flapping link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.5.1.6 snmpwalk -v2c -c public <target> TN-XSTP-MIB::tnXstpPortStatsTcnTx
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.111.2.5.1.6.1 snmpget -v2c -c public <target> TN-XSTP-MIB::tnXstpPortStatsTcnTx.1
