eltBridgeStpConfigPortRestrictedTcn
Module: ELTEX-MES-BRIDGE-EXT-MIB
OID (symbolic): ELTEX-MES-BRIDGE-EXT-MIB::eltBridgeStpConfigPortRestrictedTcn
OID (numeric): 1.3.6.1.4.1.35265.1.23.1.401.0.5.1.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Configure filtering of Spanning Tree BPDUs with TC flag set.
What is eltBridgeStpConfigPortRestrictedTcn?
This TruthValue flag enables filtering so the port ignores Spanning Tree BPDUs carrying the Topology Change (TC) flag. Admins enable it on ports facing untrusted or edge devices to prevent those devices from triggering unnecessary topology change flushes across the bridge. Setting it to true on an access port connected to an end-user switch stops that port from propagating spurious topology-change notifications into the core.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.35265.1.23.1.401.0.5.1.1.2 snmpwalk -v2c -c public <target> ELTEX-MES-BRIDGE-EXT-MIB::eltBridgeStpConfigPortRestrictedTcn
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.35265.1.23.1.401.0.5.1.1.2.1 snmpget -v2c -c public <target> ELTEX-MES-BRIDGE-EXT-MIB::eltBridgeStpConfigPortRestrictedTcn.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.35265.1.23.1.401.0.5.1.1.2.1 s <value>
