This TC describes the source of a chassis identifier.
          
The enumeration 'chassisComponent(1)' represents a chassis
identifier based on the value of entPhysicalAlias object
(defined in IETF RFC 4133) for a chassis component (i.e.,
an entPhysicalClass value of 'chassis(3)').
          
The enumeration '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.
          
The enumeration 'portComponent(3)' represents a chassis
identifier based on the value of entPhysicalAlias object
(defined in IETF RFC 4133) for a port or backplane
component (i.e., entPhysicalClass value of 'port(10)' or
'backplane(4)'), within the containing chassis.
          
The enumeration '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.
          
The enumeration '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.
          
The enumeration '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.
          
The enumeration 'local(7)' represents a chassis identifier
based on a locally defined value.
