Using the CLI to Configure Spanning Tree Protocol
Follow these steps to configure STP using the CLI.
Step 1
Enter show spanningtree port and show spanningtree switch to view the current STP status.
Step 2
If STP is enabled, you must disable it before you can change STP settings. Enter config spanningtree
switch mode disable to disable STP on all ports.
switch mode disable to disable STP on all ports.
Step 3
Enter one of these commands to configure the STP port administrative mode:
•
config spanningtree port mode 802.1d {port-number | all}
•
config spanningtree port mode fast {port-number | all}
•
config spanningtree port mode off {port-number | all}
Step 4
Enter one of these commands to configure the STP port path cost on the STP ports:
•
config spanningtree port pathcost 1-65535 {port-number | all}—Specifies a path cost from 1 to
65535 to the port.
65535 to the port.
•
config spanningtree port mode pathcost auto {port-number | all}—Enables the STP algorithm to
automatically assign the path cost. This is the default setting.
automatically assign the path cost. This is the default setting.
Step 5
Enter config spanningtree port priority 0-255 port-number to configure the port priority on STP ports.
The default priority is 128.
The default priority is 128.
Step 6
If necessary, enter config spanningtree switch bridgepriority 0-65535 to configure the controller’s
STP bridge priority. The default bridge priority is 32768.
STP bridge priority. The default bridge priority is 32768.
Step 7
If necessary, enter config spanningtree switch forwarddelay 4-30 to configure the controller’s STP
forward delay in seconds. The default forward delay is 15 seconds.
forward delay in seconds. The default forward delay is 15 seconds.
Step 8
If necessary, enter config spanningtree switch hellotime 1-10 to configure the controller’s STP hello
time in seconds. The default hello time is 2 seconds.
time in seconds. The default hello time is 2 seconds.
Step 9
If necessary, enter config spanningtree switch maxage 6-40 to configure the controller’s STP maximum
age. The default maximum age is 20 seconds.
age. The default maximum age is 20 seconds.
Hello Time (seconds)
The length of time that the controller broadcasts hello messages to
other controllers.
other controllers.
Options: 1 to 10 seconds
Default: 2 seconds
Forward Delay (seconds)
The length of time that each of the listening and learning states lasts
before the port begins forwarding.
before the port begins forwarding.
Options: 4 to 30 seconds
Default: 15 seconds
