C HAPTER 5 | Interface Configuration
Trunk Configuration
– 138 –
◆ 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.
N OTE :
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 described on page 723 ).
P ARAMETERS
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
other switches during LAG negotiations. (Range: 0-65535;
Default: 32768)
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.
◆ Port Priority – If a link goes down, LACP port priority is used to select
a backup link. (Range: 0-65535; Default: 32768)
