◆ 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.
Port Details – 802.3 Extension Power Information
◆ Remote Power Class – The port Class of the given port associated with the
remote system (PSE – Power Sourcing Equipment or PD – Powered Device).
◆ Remote Power MDI Status – Shows whether MDI power is enabled on the
given port associated with the remote system.
◆ Remote Power Pairs – “Signal” means that the signal pairs only are in use, and
“Spare” means that the spare pairs only are in use.
◆ Remote Power MDI Supported – Shows whether MDI power is supported on
the given port associated with the remote system.
◆ Remote Power Pair Controlable – Indicates whether the pair selection can be
controlled for sourcing power on the given port associated with the remote
system.
◆ Remote Power Classification – This classification is used to tag different
terminals on the Power over LAN network according to their power
consumption. Devices such as IP telephones, WLAN access points and others,
will be classified according to their power requirements.
