Creating Trunk Groups
– 115 –
â–
Ports must have the same LACP Admin Key. Using auto-
configuration of the Admin Key will avoid this problem.
â–
One of the ports at either the near end or far end must be set to
active initiation mode.
â—† Aggregation Mode Configuration located under the Static Aggregation
menu (see "Configuring Static Trunks" on page 112) also applies to
LACP.
PARAMETERS
These parameters are displayed:
◆ Port – Port identifier.
◆ LACP Enabled – Controls whether LACP is enabled on this switch port.
LACP will form an aggregation when two or more ports are connected
to the same partner. LACP can form up to 12 LAGs per switch.
◆ Key – The LACP administration key must be set to the same value for
ports that belong to the same LAG. (Range: 0-65535; Default: Auto)
Select the Specific option to manually configure a key. Use the Auto
selection to automatically set the key based on the actual link speed,
where 10Mb = 1, 100Mb = 2, and 1Gb = 3.
◆ Role – Configures active or passive LACP initiation mode. Use Active
initiation of LACP negotiation on a port to automatically send LACP
negotiation packets (once each second). Use Passive initiation mode on
a port to make it wait until it receives an LACP protocol packet from a
partner before starting negotiations.
WEB INTERFACE
To configure a dynamic trunk:
1. Click Configuration, Aggregation, LACP.
