CHAPTER 12: SPANNING TREE PROTOCOL (STP) SPANNING TREE PROTOCOL (STP)

•Priority: STP uses this to determine which ports are used for forwarding. Lower the number means higher priority. Value ranges from 0 to 255. Default is 128

•Path Cost: This is the assigned port cost value used for the switch to determine the forwarding points. Values range from 1 to 65535

•State: indicates the STP state of individual ports. Values can be Listening, Learning, Forwarding, Blocking and Disabled.

•Des. Bridge: This is the port's designated root bridge

•Des. Port: This is the port's designated root port

To enable or disable STP, enter the STP configuration mode via the stp command and use the stp enable or stp disable command.

To stp command enters STP configuration mode:

stp

The enable and disable parameters start (enable) or stop (disable) STP.

stp <enabledisable>

The stp and rstp parameters set the spanning tree protocol to be IEEE 802.1d or 802.1w (Rapid Spanning Tree Protocol).

set stp type=<stprstp>

The show active-stpcommand display which version of STP is currently active.

show active-stp

Incorrect STP settings can adversely affect network performance. GE recommends starting with the default STP settings. Changing the settings requires a detailed understanding of STP. For more information on STP, please refer to the IEEE 802.1d standard.

It is always a good idea to check which mode of STP is active. If the proper mode is not active, the configuration command stp will not be understood. To set the proper mode, use the set stp command.
