associated with a port of the remote system.
Port Details – 802.3 Extension Port Information
◆ Remote Port Auto-Neg Supported – Shows whether the given port
(associated with remote system) supports auto-negotiation.
◆ Remote Port Auto-Neg Adv-Capability – The value (bitmap) of the
ifMauAutoNegCapAdvertisedBits object (defined in IETF RFC 3636)
which is associated with a port on the remote system.
◆ Remote Port Auto-Neg Status – Shows whether port auto-
negotiation is enabled on a port associated with the remote system.
◆ Remote Port MAU Type – An integer value that indicates the
operational MAU type of the sending device. This object contains the
integer value derived from the list position of the corresponding
dot3MauType as listed in IETF RFC 3636 and is equal to the last number
in the respective dot3MauType OID.
