DES-3550 Fast Ethernet Layer 2 Switch
Parameter Description
From/To
A consecutive group of ports may be configured starting with the selected port.
Mode
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).
After setting the previous parameters, click Apply to allow your changes to be implemented. The LACP Port Table
shows which ports are active and/or passive.
