action dynamic-cost — specifies that dynamic costing will be activated if the number of
operational links is equal to or below the configured threshold value. The LAG will
remain operationally up with a cost relative to the number of operational links. The
link will only be regarded as operationally down when all links in the LAG are down.
action down — specifies that the LAG will be brought operationally down if the number
of operational links is equal to or below the configured threshold value. The LAG will
only be regarded as up when the number of operational links exceeds the configured
threshold value.

no selection-criteria
Context config>lag
Description This command specifies which criteria is used to select the active subgroup (link) of a LAG.
Every time the configuration of a link changes, the selection algorithm is applied.
The no form of this command returns the value to the default.
Default highest-count
Parameters best-port — specifies that all standby ports will have their corresponding transmitters
disabled. This parameter is used in static LAG configurations.
highest-count — specifies the subgroup with the highest number of eligible member
links. An eligible member link of a LAG is a member that can potentially become
active.
A subgroup can have a maximum of one eligible member link.
highest-weight — specifies the subgroup with the highest aggregate weight
slave-to-partner — selects, together with the selection criteria, the active subgroup. An
eligible member link of a LAG is a member that can potentially become active. This
means it is operationally up (not disabled) for use by the remote side. The slave-to-
partner parameter can be used to control whether this latter condition is taken into
account. The slave-to-partner parameter does not apply to static LAG
configurations.
It is recommended that this parameter be set.
