IEEE Single Spanning Tree (SSTP)

12

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>]

For the parameter definitions, default and possible values, refer to

Table 75

on page 329.

Here is the syntax for the STP port parameters.

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

<value> | disable | enable]

The ethernet <slot>/<portnum> parameter specifies the interface.

For descriptions of path cost and priority, their default and possible values, refer to

Table 76

on

page 329. If you enter a priority value that is not divisible by four, the software rounds it to the
nearest value.

The disable | enable parameter disables or re-enables STP on the port.

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. Refer to

“Enabling or

disabling RSTP on a single spanning tree”

on page 388.

Displaying SSTP information

To verify that SSTP is in effect, enter the following commands at any level of the CLI.

For information on the command syntax, refer to
