cmEthernetNetPortEntityIndex
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortEntityIndex
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.3
Node type: OBJECT-TYPE
Type: PhysicalIndex
Access: read-only
Description: Entity Index from ENTITY-MIB for this port.
What is cmEthernetNetPortEntityIndex?
This read-only PhysicalIndex cross-references a network-facing Ethernet port to its corresponding physical entity row in ENTITY-MIB. It matters to management systems that need to correlate this MIB's port-level configuration and status with ENTITY-MIB's physical inventory data (like slot, model, or serial number) for the same hardware. For example, an NMS displaying a chassis diagram would use cmEthernetNetPortEntityIndex to look up the matching entPhysicalEntry and show the correct slot/port label alongside this port's operational state.
