Trunk Configuration
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)
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.
Note: Configuring LACP settings for a port only applies to its administrative state,
not its operational state, and will only take effect the next time an aggregate link is
established with that port.
Note: Configuring the port partner sets the remote side of an aggregate link; i.e.,
the ports on the attached device. The command attributes have the same meaning
as those used for the port actor.
