Configuring STP Compatibility

Choosing an RSTP protocol version allows you to determine if the switch ports will operate in RSTP-only mode or are STP-compatible. This setting applies to all of the ports; you cannot set this on a per-port basis.

To configure the STP compatibility, perform the following procedure:

1.From the Main Menu, type B to select Basic Switch Configuration.

The Basic Switch Configuration Menu is shown in Figure 4 on page 30.

2.From the Basic Switch Configuration Menu, type S to select Rapid Spanning Tree Configuration.

The Rapid Spanning Tree Configuration Menu is shown in Figure 30 on page 115.

3.Type V to select Set RSTP Protocol Version. The following prompt is displayed:

Set RSTP protocol version (S/R)>

4.Type S to make the ports STP-compatible, or R to make the ports operate only in RSTP mode.
