Configure Aggregation Port - General
• Port – Port identifier. (Range: 1-12)
• LACP Status – Enables or disables LACP on a port.
Configure Aggregation Port - Actor/Partner
• Port – Port number. (Range: 1-12)
• Admin Key – The LACP administration key must be set to the same value for ports that belong
to the same LAG. (Range: 0-65535; Default – Actor: 1, Partner: 0)
By default, the Actor Admin Key is determined by port's link speed, and copied to Oper Key. The
Partner Admin Key is assigned to zero, and the Oper Key is set based upon LACP PDUs
received from the Partner.
• System Priority – LACP system priority is used to determine link aggregation group (LAG)
membership, and to identify this device to other switches during LAG negotiations.
(Range: 0-65535; Default: 32768)
System priority is combined with the switch’s MAC address to form the LAG identifier. This
identifier is used to indicate a specific LAG during LACP negotiations with other systems.
• Port Priority – If a link goes down, LACP port priority is used to select a backup link.
(Range: 0-65535; Default: 32768)
• Setting a lower value indicates a higher effective priority.
• If an active port link goes down, the backup port with the highest priority is selected to
replace the downed link. However, if two or more ports have the same LACP port priority,
the port with the lowest physical port number will be selected as the backup port.
• If an LAG already exists with the maximum number of allowed port members, and LACP is
subsequently enabled on another port using a higher priority than an existing member, the
newly configured port will replace an existing port member that has a lower priority.
NOTE
Configuring LACP settings for a port only applies to its administrative state, not its operational state,
and will only take effect the next time an aggregate link is established with that port.
Configuring the port partner sets the remote side of an aggregate link; i.e., the ports on the attached
device. The command attributes have the same meaning as those used for the port actor.
Interface
To configure the admin key for a dynamic trunk:
1. Click Interface, Trunk, Dynamic.
2. Select Configure Aggregator from the Step list.
3. Set the Admin Key and timeout for the required LACP group.
4. Click Apply.
