cmEthernetNetPortOuterTagTpid
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortOuterTagTpid
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.126
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This object allows to specify the egress Outer Tag TPID on the Ethernet Network Port.
What is cmEthernetNetPortOuterTagTpid?
This read-write Unsigned32 specifies the egress Outer Tag TPID value used on an Ethernet Network Port when the override is enabled via cmEthernetNetPortOuterTagTpidOverride. It matters because using the wrong TPID value causes downstream equipment to fail to recognize the outer tag as a VLAN tag at all, treating the frame as a different Ethertype entirely. For example, an admin interoperating with equipment requiring TPID 0x9100 for the outer tag would set cmEthernetNetPortOuterTagTpid to 0x9100 so egress frames carry the TPID that downstream equipment expects.
