Trunk Configuration
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.
If the LACP admin key is not set when a channel group is formed
N :
OTE
(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

These parameters are displayed:
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)
Configure Aggregation Port - General
Port – Port identifier. (Range: 1-10)
◆
LACP Status – Enables or disables LACP on a port.
◆
Configure Aggregation Port - Actor/Partner
Port – Port number. (Range: 1-10)
◆
◆ 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)
By default, the Actor Admin Key is determined by port's link speed, and
copied to Oper Key. The Partner Admin Key is assigned to zero, and the
Oper Key is set based upon LACP PDUs received from the Partner.
System Priority – LACP system priority is used to determine link
◆
aggregation group (LAG) membership, and to identify this device to

command described on page 747).
