802.1w Rapid Spanning Tree Protocol (RSTP) and 802.1d Spanning Tree Protocol (STP)
Figure 13-22. Example of a Configuration Supporting the STP Topology Shown
in Figure 13-20
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 13-20,
13-21, and 13-22. (The example assumes that ports A2 and A3 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:
802.1p Spanning-Tree Protocol (STP)
