Description: This object identifies the port type. An initial set of MAU types are defined in RFC 2668. The assignment of OBJECT IDENTIFIERs to new types of MAUs is managed by the IANA. If the MAU type is unknown, the object identifier

unknownMauType OBJECT IDENTIFIER ::= { 0 0 }

is returned. Note that unknownMauType is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value.

This object represents the operational type of the MAU, as determined by either (1) the result of the auto-negotiation function or (2) if auto-negotiation is not enabled or is not implemented for this MAU, by the value of the object agentPortDefaultType, or (3) for the GigE card a value determined by the GBIC connected to the card. In case (2), a set to the object agentPortDefaultType will force the MAU into the new operating mode.

The valid values for this object are:
