cmEthernetNetPortCpdEthertype
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortCpdEthertype
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.8.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This enables provides the Filter Ethertype to match.
What is cmEthernetNetPortCpdEthertype?
This read-write Integer32 (0..65535) specifies the Ethertype a CPD filter row on an Ethernet Network Port must match to apply its disposition. It matters for the same reason as the flow-level Ethertype object: many Layer 2 control protocols are distinguished chiefly by this field, so setting it precisely targets the intended protocol at the port level. For example, an admin wanting a port-level filter specifically for PVSTP+ would set cmEthernetNetPortCpdEthertype to 0x10B, matching that protocol's known Ethertype value.
