You can set the path cost for a bridge port. The path cost is the cost to be
added to the root cost field in a configuration message received on this
port. This value is used to determine the path cost to the root through this
port. You can set this value individually on each port.
A larger path cost value makes the LAN reached through the port more
likely to be low in the Spanning Tree topology. The lower the LAN is in the
topology means the less through traffic it will carry. For this reason, you may
want to assign a large path cost to a LAN with a lower bandwidth or one on
which you want to minimize traffic.
To configure the path cost:
1 From the top level of the Administration Console, enter:
bridge port stpCost
