Link Layer Discovery Protocol
– 390 –
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.
•
Supported Capabilities – The supported set of capabilities that define
the primary function(s) of the port:
