Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortCpdV2L2PTTunnelMac
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.15.1.29
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-write
Description: Configurable Layer 2 Protocol Tunneling MAC Address. For protocols STP, CDP and VTP, with control protocol disposition as pass-thru-l2pt, this configured MAC address replaces the DA, upon encapsulation. For decapsulation, protocol signature and this configured MAC address are matched and the MAC address is replaced with the protocol's inferred MAC address.
What is cmEthernetNetPortCpdV2L2PTTunnelMac?
cmEthernetNetPortCpdV2L2PTTunnelMac is a read-write MAC address configured on the Ethernet network-facing port that replaces the destination address of STP, CDP, and VTP frames when their disposition is pass-thru-l2pt, and is used together with the protocol signature to recognize those frames again on decapsulation at the far end. Since this is the network-side counterpart to the access-port tunnel MAC, the two need to agree only if this NE is one leg of a matched tunnel pair rather than the tunnel's originating device. For example, a provider edge device tunneling a customer's VTP domain across an MPLS-connected network port would set this address to the value its remote L2PT peer expects on decapsulation.
