◆ 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 Controllable – 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.
Port Details – 802.3 Extension Trunk Information
◆ Remote Link Aggregation Capable – Shows if the remote port is not in link
aggregation state and/or it does not support link aggregation.
◆ Remote Link Aggregation Status – The current aggregation status of the link.
◆ Remote Link Port ID – This object contains the IEEE 802.3 aggregated port
identifier, aAggPortID (IEEE 802.3-2002, 30.7.2.1.1), derived from the ifNumber
of the ifIndex for the port component associated with the remote system. If the
remote port is not in link aggregation state and/or it does not support link
aggregation, this value should be zero.
Port Details – 802.3 Extension Frame Information
◆ Remote Max Frame Size – An integer value indicating the maximum
supported frame size in octets on the port component associated with the
remote system.
Port Details – LLDP-MED Capability

◆ Device Class – Any of the following categories of endpoint devices:
■
Class 1 – The most basic class of endpoint devices.
■
Class 2 – Endpoint devices that supports media stream capabilities.
■
Class 3 – Endpoint devices that directly supports end users of the IP
communication systems.
■
Network Connectivity Device – Devices that provide access to the IEEE 802
based LAN infrastructure for LLDP-MED endpoint devices. These may be
any LAN access device including LAN switch/router, IEEE 802.1 bridge, IEEE
802.3 repeater, IEEE 802.11 wireless access point, or any device that
supports the IEEE 802.1AB and MED extensions defined by this Standard
and can relay IEEE 802 frames via any method.
8. These fields are only displayed for end-node devices advertising LLDP-MED TLVs.
