ldPortDestMac
Module: NMS-LOOPBACK-DETECT-MIB
OID (symbolic): NMS-LOOPBACK-DETECT-MIB::ldPortDestMac
OID (numeric): 1.3.6.1.4.1.11606.10.9.252.2.1.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: Configuration the loopback detection's dest mac address.
What is ldPortDestMac?
A read-write octet string configuring the destination MAC address used in the loopback detection packets sent on this port. This lets an admin control what MAC address the switch's own loop-detection probe frames use as their destination, which matters for distinguishing genuine loop-detection traffic from other frames when analyzing captures or troubleshooting. An admin might leave this at the vendor default destination MAC unless a specific network design requires a custom detection address.
Examples
Walk all instances (SNMPv2c):
