Link Aggregation Control Protocol (LACP) - LACP LAG negotiate Aggregated Port links with other LACP ports located on a
different device. LACP allows switches connected to each other to discover automatically whether any ports are member of the
same LAG.
This page allows the user to inspect the current LACP port configurations, and possibly change them as well. The LACP

Description
The switch port number.
Controls whether LACP is enabled on this switch port. LACP will form an
aggregation when 2 or more ports are connected to the same partner.
The Key value incurred by the port, range 1-65535 . The Auto setting will set the
key as appropriate by the physical link speed, 10Mb = 1, 100Mb = 2, 1Gb = 3.
Using the Specific setting, a user-defined value can be entered. Ports with the
same Key value can participate in the same aggregation group, while ports with
different keys cannot.
The default setting is "Auto"
The Role shows the LACP activity status. The Active will transmit LACP packets
each second, while Passive will wait for a LACP packet from a partner (speak if
spoken to).
The Timeout controls the period between BPDU transmissions. Fast will transmit
LACP packets each second, while Slow will wait for 30 seconds before sending a
