Configuring RSTP

The process for configuring RSTP is as follows.

1. Enable RSTP by using the global protocol spanning-tree command.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp></rstp>
   	</spanning-tree>
   </protocol>

2. Designate the root switch by using the bridge-priority command. The range is 0 through 61440 and the priority values can be set only in increments of 4096.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp>
   			<bridge-priority>32768</bridge-priority>
   		</rstp>
   	</spanning-tree>
   </protocol>

3. Configure the bridge forward delay value to set the time an interface spends in each of the listening and learning states.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp>
   			<forward-delay>30</forward-delay>
   		</rstp>
   	</spanning-tree>
   </protocol>

4. Configure the bridge maximum aging time value to set the interval time in seconds between messages that the spanning tree receives from the interface.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp>
   			<max-age>40</max-age>
   		</rstp>
   	</spanning-tree>
   </protocol>

5. Enable the error-disable-timeout timer.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp>
   			<error-disable-timeout>
   				<enable></enable>
   			</error-disable-timeout>
   		</rstp>
   	</spanning-tree>
   </protocol>

6. Configure the error-disable-timeout interval value to set the timeout for errors on an interface.
   

   <protocol xmlns="urn:brocade.com:mgmt:brocade-interface">
   	<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">
   		<rstp>
   			<error-disable-timeout>
   				<interval>500</interval>
   			</error-disable-timeout>
   		</rstp>
   	</spanning-tree>
   </protocol>
