Configuring a Dynamic Trunk
Use the Interface > Trunk > Dynamic pages to set the administrative key for an aggregation group, enable LACP on a port,
configure protocol parameters for local and partner ports, or to set Ethernet connection parameters.
Command Usage
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.
If the target switch has also enabled LACP on the connected ports, the trunk will be activated automatically.
A trunk formed with another switch using LACP will automatically be assigned the next available trunk ID.
If more than eight ports attached to the same target switch have LACP enabled, the additional ports will be placed in
standby mode, and will only be enabled if one of the active links fails.
All ports on both ends of an LACP trunk must be configured for full duplex, and auto-negotiation.
Ports are only allowed to join the same Link Aggregation Group (LAG) if (1) the LACP port system priority matches, (2) the
LACP port admin key matches, and (3) the LAG admin key matches (if configured). However, if the LAG admin key is set,
then the port admin key must be set to the same value for a port to be allowed to join that group.
NOTE:
If the LACP admin key is not set when a channel group is formed (i.e., it has a null value of 0), the operational value of this key
is set to the same value as the port admin key used by the interfaces that joined the group (see the "show lacp internal" command in
the CLI Reference Guide).

Configure Aggregator
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)
If the port channel admin key is not set when a channel group is formed (i.e., it has the null value
of 0), this key is set to the same value as the port admin key (see Configure Aggregation Port -
Actor/Partner) 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.
If the port channel admin key is set to a non-default value, the operational key is based upon LACP
PDUs received from the partner, and the channel admin key is reset to the default value. The trunk
identifier will also be changed by this process.
