Description: This object is used to identify the operational state of the Multi-Point MAC Control sublayer as defined in [802.3ah], clause 64. Reading olt(1) for an

OLT (server) mode and onu(2) for an ONU (client) mode. This object is used to identify the operational mode for the MPCP tables. This object is applicable for an OLT, with the same value for all virtual interfaces, and for an ONU.

What is dot3MpcpMode?

This reports whether the interface is operating as an OLT (server, value olt) or an ONU (client, value onu) for the MPCP protocol. It's a read-only identity check useful when troubleshooting a PON link to confirm which end of the fiber a given ifIndex represents.
