ldPortVlanContrl
Module: NMS-LOOPBACK-DETECT-MIB
OID (symbolic): NMS-LOOPBACK-DETECT-MIB::ldPortVlanContrl
OID (numeric): 1.3.6.1.4.1.11606.10.9.252.2.1.5
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: Configure the vlan to loopback detect.
What is ldPortVlanContrl?
A read-write octet string, likely a VLAN bitmap, configuring which VLANs are covered by loopback detection on this port. This lets an admin scope loopback detection to specific VLANs on a trunk port rather than applying it to every VLAN carried on that port. An admin might restrict loopback detection to only the VLANs actually expected to be trunked on a given uplink, avoiding false positives on unused VLANs.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.252.2.1.5 snmpwalk -v2c -c public <target> NMS-LOOPBACK-DETECT-MIB::ldPortVlanContrl
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.252.2.1.5.1 snmpget -v2c -c public <target> NMS-LOOPBACK-DETECT-MIB::ldPortVlanContrl.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11606.10.9.252.2.1.5.1 s <value>
