The PortIdSubtype is an enumeration representing different types of port identifier as defined in IEEE 802.1AB-2016, Table 8-3, port ID subtype.

The PortIdSubtype Enumeration is defined in Table 36.

Description

InterfaceAlias

1

Represents a port identifier based on the ifAlias MIB object defined in IETF RFC 2863.

PortComponent

2

Represents a port identifier based on the value of entPhysicalAlias (defined in IETF RFC 2737) for a port component (i.e., entPhysicalClass value of port(10) or backplane(4)), within the containing chassis.

MacAddress

3

Represents a port identifier based on a unicast source address (encoded in network byte order and IEEE 802.3 canonical bit order) which has been detected by the agent and associated with a particular port (IEEE Std 802-2014).

NetworkAddress

4

Represents a port identifier based on a network address, detected by the agent and associated with a particular port.

InterfaceName

5

Represents a port identifier based on the ifName MIB object, defined in IETF RFC 2863.

AgentCircuitId

6

Represents a port identifier based on the agent-local identifier of the circuit (defined in IETF RFC 3046), detected by the agent and associated with a particular port.

Local

7

Represents a port identifier based on a value locally assigned.

Its representation in the AddressSpace is defined in Table 37.
