3.3.2 LACP
Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification) as their trunking method can choose their
unique LACP GroupID to form a logic “trunked port”. The benefit of using LACP is that a port makes an agreement with its peer
port before it becomes a ready member of a “trunk group” (also called aggregator).
LACP is safer than the other trunking method, static trunk.
Configuration
This page allows the user to inspect the current LACP port configurations, and possibly change them as well. An LACP trunk
group with more than one ready member-ports is a “real trunked” group. An LACP trunk group with only one or less than one
ready member-ports is not a “real trunked” group.
Web Interface
To configure the Trunk Aggregation LACP parameters in the Web interface:
1. Click Configuration, LACP, Configuration.
2. Select enable or disable the LACP on the port of the switch. Select the Key parameter with Auto or Specific (Default is Auto).
3. Select the Role from the Active or Passive pulldown menu. (Default is Active).
4. Click the Save Button to save the setting.
5. To cancel the setting, click the Reset button to revert to previously saved values.

Parameter Description
• Port: The switch port number.
• LACP Enabled: 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. LACP can form a maximum of 12 LLAGs per switch and 2 GLAGs.
