Description: This value contain port ifIndex from which the request about the last change of topology came. If value is 0 - topology wasn't changed yet.

What is eltdot1dStpLastTopologyChangePort?

This integer reports the ifIndex of the port that generated the most recent classic Spanning Tree (802.1D) topology change on the bridge. Admins use it to diagnose which link is causing repeated topology recalculations and MAC table flushes. A value of 0 indicates the topology has not changed since the bridge came up, while a nonzero value identifies the offending port's ifIndex.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.35265.1.23.1.401.0.5.2
snmpwalk -v2c -c public <target> ELTEX-MES-BRIDGE-EXT-MIB::eltdot1dStpLastTopologyChangePort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.35265.1.23.1.401.0.5.2.1
snmpget -v2c -c public <target> ELTEX-MES-BRIDGE-EXT-MIB::eltdot1dStpLastTopologyChangePort.1
