Configure Aggregation Port - Actor/Partner
Port – Port number. (Range: 1-12)
◆
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 – Actor: 1, Partner: 0)
By default, the actor's operational key is determined by port's link
speed (1000f - 4, 100f - 3, 10f - 2), and copied to the admin key.
◆ 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)
Setting a lower value indicates a higher effective priority.
■
If an active port link goes down, the backup port with the highest
■
priority is selected to replace the downed link. However, if two or
more ports have the same LACP port priority, the port with the
lowest physical port number will be selected as the backup port.
If an LAG already exists with the maximum number of allowed port
■
members, and LACP is subsequently enabled on another port using
a higher priority than an existing member, the newly configured
port will replace an existing port member that has a lower priority.
Configuring LACP settings for a port only applies to its administrative
N :
OTE
state, not its operational state, and will only take effect the next time an
aggregate link is established with that port.
Configuring the port partner sets the remote side of an aggregate
N :
OTE
link; i.e., the ports on the attached device. The command attributes have
the same meaning as those used for the port actor.
