IEEE Single Spanning Tree (SSTP)

To change an STP parameter for a specific port, enter commands such as the following.

Brocade(config) spanning-tree single ethernet 1/1 priority 10

The commands shown above override the global setting for STP priority and set the priority to 10 for
port 1/1.

Here is the syntax for the global STP parameters:

Syntax: [no] spanning-tree single [forward-delay value]

[hello-time value] | [maximum-age time] | [priority value]

Here is the syntax for the STP port parameters:

Syntax: [no] spanning-tree single [ethernet slot/portnum path-cost value | priority value]

For the parameter definitions and possible values, refer to

NOTE

Both commands listed above are entered at the global CONFIG level.

Also, you can use the rstp single command to control the topology for VLANs.
