ports with the same speed.
• Ports assigned to a common port channel must meet the following criteria:
• Ports must have the same LACP System Priority.
Notes: 1.
If the port channel admin key is not set (through the CLI) when a channel
group is formed (i.e., it has a null value of 0), this key is set to the same value
as the port admin key used by the interfaces that joined the group (lacp
admin key).
2.
To avoid creating a loop in the network, be sure you enable LACP before
connecting the ports, and also disconnect the ports before disabling LACP.
3.
If the target switch has also enabled LACP on the connected ports, the trunk
will be activated automatically.
4.
A trunk formed with another switch using LACP will automatically be
assigned the next available trunk ID.
5.
All ports on both ends of an LACP trunk must be configured for full duplex,
either by forced mode or auto-negotiation.
The Interface LACP Configuration Page contains parameters for defining the LACP
ports.
Command Attributes
• LACP System Priority — Determines the link aggregation group (LAG)
membership, and to identify this device to other switches during LAG negotiations.
Ports must be configured with the same system priority to join the same LAG.
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. The field range is 1 - 65535, and the default is 1.
• Unit No. — Displays the stacking member for which the LACP parameters are
displayed
• Port — Displays the port number to which timeout and priority values are assigned.
• Port-Priority — Displays the LACP priority value for the port. The field range is
1-65535.
• LACP Timeout — Displays the administrative LACP timeout.
