Configuring the Switch
3-140
3
CLI – The following example configures LACP parameters for ports 1-4. Ports 1-4
are used as active members of the LAG.
Configuring Parameters for LACP Groups
Use the Aggregator page to configure system parameters which apply to specific
LACP groups.
Command Attributes
• Admin Key – LACP administration key is used to identify a specific link
aggregation group (LAG) during local LACP setup on the switch. (Range: 0-65535)
Ports are only allowed to join the same LAG if (1) the LACP port system priority
matches, (2) the LACP port admin key matches, and (3) the LACP port channel
admin key matches (if configured).
If the port channel admin key is not set when a channel group is formed (that is, it
has the 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. Note that when the LAG is no longer used,
the port channel admin key is reset to 0.
