• If a 16-bit path cost value is in use and the path_cost for a link aggregate is set to zero, the following 

default values based on link speed and link aggregate size are used. Note that for Gigabit ports the 
aggregate size is not applicable in this case: 

-> bridge mode flat

-> bridge 1x1 200 4/1 path cost 4

-> bridge 1x1 300 16 path cost 200000

-> bridge mode 1x1

-> bridge 1x1 400 5/10 path cost 19

-> bridge 1x1 500 1/24 path cost 20000
