Short Timeout – 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.
◆
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.
◆
System MAC Address – The device MAC address assigned to each trunk.
Configure Aggregation Port - General
◆
Port – Port identifier. (Range: 1-10/28)
◆
LACP Status – Enables or disables LACP on a port.
Configure Aggregation Port - Actor/Partner
◆
Port – Port number. (Range: 1-10/28)
◆
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)
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.

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)
