5.3.1.9 ChassisIdSubtype Enumeration
The ChassisIdSubtype is an enumeration representing different types of chassis identifier as defined in IEEE 802.1AB-2016, Table 8-2, chassis ID subtype.
The ChassisIdSubtypeEnumeration is defined in Table 34.

Description
ChassisComponent
1
Represents a chassis identifier based on the value of entPhysicalAlias object (defined in IETF RFC 2737) for a chassis component (i.e., an entPhysicalClass value of chassis(3))
InterfaceAlias
2
Represents a chassis identifier based on the value of ifAlias object (defined in IETF RFC 2863) for an interface on the containing chassis.
PortComponent
3
Represents a chassis identifier based on the value of entPhysicalAlias object (defined in IETF RFC 2737) for a port or backplane component (i.e., entPhysicalClass has a value of port(10), or backplane(4)), within the containing chassis.
MacAddress
4
Represents a chassis identifier based on the value of a unicast source address (encoded in network byte order and IEEE 802.3 canonical bit order) of a port on the containing chassis as defined in IEEE Std 802-2014.
NetworkAddress
5
Represents a chassis identifier based on a network address associated with a particular chassis. The encoded address is actually composed of two fields. The first field is a single octet, representing the IANA AddressFamilyNumbers value for the specific address type, and the second field is the network address value.
InterfaceName
6
Represents a chassis identifier based on the value of ifName object (defined in IETF RFC 2863) for an interface on the containing chassis.
Local
7
Represents a chassis identifier based on a locally defined value.
Its representation in the AddressSpace is defined in Table 35.
