Use the Interface > Trunk > Dynamic pages to set the administrative key for an aggregation group, enable LACP on a port, and configure protocol parameters for local and partner ports, or to set Ethernet connection parameters.
LACP administration key is used to identify a specific link aggregation group (LAG) during local LACP setup on the switch. (Range: 0-65535)
If the port channel admin key is not set when a channel group is formed (i.e., it has the null value of 0), this key is set to the same value as the port admin key (see Configure Aggregation Port - Actor/Partner) used by the interfaces that joined the group. Note that when the LAG is no longer used, the port channel admin key is reset to 0.
If the port channel admin key is set to a non-default value, the operational key is based upon LACP PDUs received from the partner, and the channel admin key is reset to the default value. The trunk identifier will also be changed by this process.
The timeout to wait for the next LACP data unit (LACPDU):
Specifies a slow timeout of 90 seconds. (This is the default setting.)
Specifies a fast timeout of 3 seconds.
The timeout is set in the LACP timeout bit of the Actor State field in transmitted LACPDUs. When the partner switch receives an LACPDU set with a short timeout from the actor switch, the partner adjusts the transmit LACPDU interval to 1 second. When it receives an LACPDU set with a long timeout from the actor, it adjusts the transmit LACPDU interval to 30 seconds.
If the actor does not receive an LACPDU from its partner before the configured timeout expires, the partner port information will be deleted from the LACP group.
When a dynamic port-channel member leaves a port-channel, the default timeout value will be restored on that port.
When a dynamic port-channel is torn down, the configured timeout value will be retained. When the dynamic port-channel is constructed again, that timeout value will be used.
LACP system priority is used to determine link aggregation group (LAG) membership, and to identify this device to other switches during LAG negotiations.
The device MAC address assigned to each trunk.
Port identifier.
Enables or disables LACP on a port.
Port identifier.
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)
Once the remote side of a link has been established, LACP operational settings are already in use on that side. Configuring LACP settings for the partner only applies to its administrative state, not its operational state.
Note: Configuring the partner admin-key does not affect remote or local switch operation. The local switch just records the partner admin-key for user reference.
By default, the actor's operational key is determined by port's link speed (1000f - 4, 100f - 3, 10f - 2), and copied to the admin key.
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.
If a link goes down, LACP port priority is used to select a backup link. (Range: 0-65535; Default: 32768)
