Bridge Priority Enter a number between 0 and 61440 as bridge priority of the ZyWALL.
Bridge priority is used in determining the root switch, root port and
designated port. The switch with the highest priority (lowest numeric value)
becomes the root. If multiple devices have the lowest priority, the device
with the lowest MAC address becomes the root.
The lower the numeric value you assign, the higher the priority for this
bridge.
Bridge Priority determines the root bridge, which in turn determines Hello
Time, Max Age and Forward Delay.
Bridge Hello Time Enter an interval (between 1 and 10) in seconds that the root bridge
waits before sending a hello packet.
Bridge Max Age Enter an interval (between 6 and 40) in seconds that a bridge waits to
get a Hello BPDU from the root bridge.
Forward Delay Enter the length of time (between 4 and 30) in seconds that a bridge
remains in the listening and learning port states. The default is 15 seconds.
