Fast-Uplink Spanning Tree Protocol (STP)

STP Enabled on the

Switch

Fast-Uplink STP

Configured on Port 1

and Trunk 1 (Trk1)

Figure 78. Example of a Configuration Supporting the STP Topology Shown in Figure 76

Using the CLI To Configure Fast-Uplink STP. This example uses the CLI to configure the switch for the fast-uplink operation shown in figures 76, 77, and 78. (The example assumes that ports 2 and 3 are already configured as members of the port trunk—Trk1, and all other STP parameters are left in their default state.)

Note that the default STP Protocol Version is RSTP (Rapid STP, or 802.1w). Thus, if the switch is set to the STP default, you must change it to the STP (802.1D) Protocol Version before you can configure Fast-Uplink. For example:

Lists STP configuration.

Shows the default

STP protocol version.

1. Changes the Spanning-Tree protocol to STP (required for Fast-Uplink).

2. Saves the change to the startup-configuration

3. Reboots the switch. (Required for this configuration change.)
