The main use of the two parts of this dialogue box is to vary the path
cost. These two interfaces are within the DeskStream and for optimal
network management we don’t want these to be standby or blocking
bridges. The local interface, by default will have a very low path cost
(2) and so should always be designated or forwarding. The SRB
interface is currently defaulted to auto path cost and so will get a
value based on the ring speed divided into 1000 (62 for 16Mbps, 10
for 100Mbps). It might be sensible to lower this manually.
