Port Configuration
8-10
8
CLI
– The following example enables LACP for ports 1 to 6. Just connect these ports
to LACP-enabled trunk ports on another switch to form a trunk.
Configuring LACP Parameters
Dynamically Creating a Port Channel –
Ports assigned to a common port channel must meet the following criteria:
• Ports must have the same LACP System Priority.
• Ports must have the same LACP port Admin Key.
• However, if the “port channel” Admin Key is set (page 4-142), then the port Admin
Key must be set to the same value for a port to be allowed to join a channel group.
Note
– If the port channel admin key (lacp admin key, page 28-6) 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, as described in this section and on page 28-5).
Command Attributes
Set Port Actor –
This menu sets the local side of an aggregate link; i.e., the ports on
this switch.
•
Port
– Port number. (Range: 1-25/50)
•
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)
