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 4-192) 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 4-191).
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: 1-8)
• 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)
- 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.
• 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: 1)
