bridge will not send or receive BPDUs, and will thus not 

participate in the Spanning Tree Protocol. If your bridge 
isn't the only bridge on the LAN, or if there are loops in the 

LAN's topology, DO NOT turn this option off.   Turning this 
option off may impair  network traffic, so be careful.

setbridgeprio  <bridge>  <priority>

sets the bridge's priority to <priority>. The priority value 
is an unsigned 16-bit quantity (a number between 0 and 65535), 

and has no dimension. Lower priority values are better. The 
bridge with the lowest priority will be elected Root Bridge.

setfd  <bridge>  <time>

sets the bridge's bridge forward delay to <time> seconds.

sethello <bridge> <time>
sets the bridge's bridge hello time to <time> seconds.

setmaxage  <bridge>  <time>

sets the bridge's maximum message age to <time> seconds.

setpathcost  <bridge>  <zre#>  <cost>
sets the port cost of the port (zre#) to <cost>. This is a 

dimensionless metric. The path cost is set to 100 for all 
OpenArchitect switch ports by default. For the OpenArchitect 

switch a port is zre1, zre2, …      IEEE 802.d recommends the 
following:

setportprio  <bridge>  <zre#>  <priority>

sets the port's priority to <priority>. The priority value  (a 
number between 0 and 255), and has no dimension. This metric 

is used in the designated port and root port selection 
algorithms. For the OpenArchitect switch a port is zre1, zre2, 

…

brctl(8) replaces the older brcfg tool.
