Configuring RSTP

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>

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>

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>

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>

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>

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>
