ldPortDefaultExistence
Module: NMS-LOOPBACK-DETECT-MIB
OID (symbolic): NMS-LOOPBACK-DETECT-MIB::ldPortDefaultExistence
OID (numeric): 1.3.6.1.4.1.11606.10.9.252.2.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Configure whether there is loopback under the port.
What is ldPortDefaultExistence?
A read-write boolean, true(1) or false(2), configuring whether a loopback is considered to exist under this port by default. This lets an admin set the baseline assumption for a port's loop state, which the actual detection status then reports against, though the source description doesn't fully spell out how this baseline interacts with live detection. An admin would typically leave this at false(2) for normal ports, only changing it for ports with known unusual wiring configurations.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.252.2.1.3 snmpwalk -v2c -c public <target> NMS-LOOPBACK-DETECT-MIB::ldPortDefaultExistence
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.252.2.1.3.1 snmpget -v2c -c public <target> NMS-LOOPBACK-DETECT-MIB::ldPortDefaultExistence.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11606.10.9.252.2.1.3.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ldPortDefaultExistence.1
