Spanning Tree Protocol Configuration
Spanning Tree Protocol as defined by IEEE 802.1D is disabled by default on the Switch. This is to
allow the Switch to progress through the learning more quickly when it is first connected to the network.
Use the STP Switch Settings menu to enable and adjust STP settings for Switch. To disable STP for
individual ports, use the Port Spanning Tree menu.
STP Switch Settings
The following figures and tables describe the configuration of the Spanning Tree Protocol (STP) on the
switch, system-wide. STP must be enabled system-wide in order to effectively enable or disable it on a
per port basis (see next section).
Figure 6- 16. STP Switch Settings Menu
Set the parameters listed below in the STP Switch Settings menu.

.
Bridge Max Age
(6-40 Sec)
The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports
(except for designated ports) should receive configuration messages at
regular intervals. Any port that ages out STP information (provided in the
last configuration message) becomes the designated port for the attached
LAN. If it is a root port, a new root port is selected from among the device
ports attached to the network.
The minimum value is the higher of 6 or [2 x (Bridge Hello Time +1)].
The maximum value is the lower of 40 or [2 x (Bridge Forward Delay
–
1)].
Default = 20 Default = 20
Bridge Hello Time
(1-10 Sec)
The time interval (in seconds) at which the root device transmits a
configuration message. Default = 2
