Description
Select the unit you want to configure.
A consecutive group of ports may be configured starting with the selected port.
Active - Active LACP ports are capable of processing and sending LACP control frames.
This allows LACP compliant devices to negotiate the aggregated link so the group may
be changed dynamically as needs require. In order to utilize the ability to change an
aggregated port group, that is, to add or subtract ports from the group, at least one of the
participating devices must designate LACP ports as active. Both devices must support
LACP.
Passive - LACP ports that are designated as passive cannot initially send LACP control
frames. In order to allow the linked port group to negotiate adjustments and make
changes dynamically, one end of the connection must have "active" LACP ports (see
above).
