When is the portvlancost form of load balancing useful? What is the full syntax of the portvlancost command? What is the one confusing aspect of this technique?
The portvlancost form of load balancing is useful in almost all situations. It is the most flexible form of STP load balancing. The full syntax of the portvlancost command is:
set spantree portvlancost mod_num/port_num [cost cost_value] [preferred_vlans]
One confusing aspect to this command is that it only allows two cost values to be set for each port. One value is set with the portcost command and the other is set with the portvlancost command.
