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.
