Fast-Uplink Spanning Tree Protocol (STP)
Fast-Uplink Spanning Tree Protocol (STP)
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.)
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:
to the STP default, you must change it to the STP (802.1D) Protocol Version before you can configure
Fast-Uplink. For example:
