MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
• : indicates the type of port - TP indicates Twisted Pair
Type
• : STP uses this to determine which ports are used for forwarding. Lower the
Priority
number means higher priority. Value ranges from 0 to 255. Default is 128
• : This is the assigned port cost value used for the switch to determine the
Path Cost
forwarding points. Values range from 1 to 65535
• : indicates the STP state of individual ports. Values can be Listening, Learning,
State
Forwarding, Blocking and Disabled.
• : This is the port's designated root bridge
Des. Bridge
• : This is the port's designated root port
Des. Port
To enable or disable STP, enter the STP configuration mode via the
the or

To command enters STP configuration mode:
stp
stp
The and parameters start (enable) or stop (disable) STP.
enable disable
stp <enable|disable>
The and parameters set the spanning tree protocol to be IEEE 802.1d or 802.1w
stp rstp
(Rapid Spanning Tree Protocol).
set stp type=<stp|rstp>
The command display which version of STP is currently active.
show active-stp
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
use the command.
