Configuring Rapid Reconfiguration Spanning Tree (RSTP)

Configuring RSTP

The default switch configuration has Spanning Tree disabled with RSTP as the selected protocol. 
That is, when Spanning Tree is enabled, RSTP is the version of Spanning Tree that is enabled, by 
default.

To optimize the RSTP configuration on your switch, follow these steps (note that for the Menu 
method, all of these steps can be performed at the same time by making all the necessary edits on 
the Spanning Tree Operation screen and then saving the configuration changes):

1.

Set the switch to support RSTP  (RSTP is the default):

 

spanning-tree protocol-version rstp

 Main Menu —> 2. Switch Configuration —> 4. Spanning Tree Operation —> select 

Protocol Version: 

RSTP

2.

Set the “point-to-point-mac” value to false on all ports that are connected to shared LAN 
segments (that is, to connections to hubs):

 

spanning-tree [ethernet] <port-list> point-to-point-mac force-false

 Main Menu —> 2. Switch Configuration —> 4. Spanning Tree Operation —> for each 

appropriate port, select Point-to-Point: 

Force-False

3.

Set the “edge-port” value to false for all ports connected to other switches, bridges, and hubs:

 

no spanning-tree [ethernet] <port-list> edge-port

 Main Menu —> 2. Switch Configuration —> 4. Spanning Tree Operation —> for each 

appropriate port, select Edge: 

No

4.

Set the “mcheck” value to false for all ports that are connected to devices that are known to be 
running IEEE 802.1D STP:

 

no spanning-tree [ethernet] <port-list> mcheck

 Main Menu —> 2. Switch Configuration —> 4. Spanning Tree Operation —> for each 

appropriate port, select MCheck: 

No

5.

Enable RSTP Spanning Tree:

 

spanning-tree

 Main Menu —> 2. Switch Configuration —> 4. Spanning Tree Operation —> select

STP Enabled: 

Yes
