Spanning Tree Priority; Bridge Max Age; Bridge Hello Timer - Proxim RangeLAN2 7500 User Manual

The network's bridges determine who should become inactive
based on several parameters which you may configure on
RangeLAN2 7500 using the configuration program CFG.EXE or
a network management station which supports the IEEE 802.1d
Bridge MIB (RFC 1493).

Spanning Tree Priority

This parameter sets the priority of RangeLAN2 7500 in the
spanning tree created on the network. It is used to determine the
root node and the branches of the tree as well as resolving
conflicts to decide which bridge on a network will become
inactive when there is a loop. In the event that two bridges have
the same priority, the unique physical address breaks the tie.
The lower value has the higher priority. You may choose a
value of 0 to 65535 with the RangeLAN2 7500 default being set
to 32,768.

Bridge Max Age

When the RangeLAN2 7500 is acting as the root, it will use this
parameter to determine the maximum amount of time before
discarding hello packet data for all bridges on the network. This
parameter is specified in seconds between 6 and 40 with a
default value of 20.

Bridge Hello Timer

When the RangeLAN2 7500 is acting as the root, it will use this
parameter to determine the interval of time between hello pack-
ets. If this parameter is set too high, the network will not
quickly resolve contention problems. However, if the parameter
is set too low, the network will be crowded with hello packet
traffic. This parameter is specified in seconds between 1 and 10
with a default value of 2.
