port-type
Syntax port-type {standard | hsmda-ports}
no port-type
Context config>lag
Description This command specifies the type of ports allowed in this LAG.
Parameters standard — Allows all non-HSMDA type ports to be added to this LAG. 
hsmda-ports — Limits the LAG members to be high-speed MDA (HSMDA) ports only.
selection-criteria
Syntax selection-criteria [highest-count | highest-weight] [slave-to-partner]
no selection-criteria
Context config>lag
Description This command specifies which selection criteria should be used to select the active sub-group.
Default highest-count
Parameters highest-count — Specifies sub-group with the highest number of eligible members.
highest-weight — Specifies sub-group with the highest aggregate weight.
slave-to-partner — The slave-to-partner keyword specifies that it, together with the selection 
criteria, should be used to select the active sub-group. An eligible member is a lag-member link 
which 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 or not this latter 
condition is taken into account.
