Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3MpcpLinkID

OID (numeric): 1.3.6.1.2.1.155.1.1.1.1.5

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: An object that identifies the Logical Link Identifier (LLID) associated with the MAC of the virtual link as specified in [802.3ah], clause 65.1.3.2.2. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface. The ONU and the corresponding virtual MAC of the OLT, for the same virtual link, have the same value. Value is assigned when the ONU registers. Value is freed when the ONU deregisters.

What is dot3MpcpLinkID?

This is the Logical Link Identifier (LLID) assigned to this virtual link's MAC when an ONU registers with the OLT. Since the OLT and the matching ONU share the same LLID value for the same virtual link, admins can use it to correlate OLT-side and ONU-side rows for the same subscriber connection.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.155.1.1.1.1.5
snmpwalk -v2c -c public <target> DOT3-EPON-MIB::dot3MpcpLinkID

Get a specific instance (index 1):
