Configuring PVST and Rapid PVST

The basic process for configuring PVST or Rapid PVST is as follows.

1. Issue the <edit-config> RPC to configure the <protocol> node in the

urn:brocade.com:mgmt:brocade-interface namespace.

2. Under the <protocol> node, include the <spanning-tree> node from the

urn:brocade.com:mgmt:brocade-xstp namespace.

3. Under the <spanning-tree> node, include the <pvst> or <rpvst> node element to access the

PVST or Rapid PVST mode parameters.

For more details, refer to “Enabling STP, RSTP, MSTP, PVST, or Rapid PVST” on page 338.

4. Under the <pvst> or <rpvst> node, include the <bridge-priority> node element and specify the

priority.

A lower priority is more likely to designate the root switch. For more details, refer to “Specifying

the bridge priority for all xSTP” on page 340.

5. Under the <pvst> or <rpvst> node, include the <forward-delay> element and specify how long

an interface remains in the listening and learning states before the interface begins forwarding

all spanning tree instances.

For more details, refer to “Specifying the bridge forward delay for all xSTP” on page 342.

6. Under the <pvst> or <rpvst> node, specify a <hello-time> element to specify how often the

switch interface broadcasts hello Bridge Protocol Data Units (BPDUs) to other devices.

For more details, refer to “Specifying the bridge hello time for all xSTP” on page 348.

7. Under the <pvst> or <rpvst> node, include the <max-age> leaf element and control the

maximum length of time that passes before an interface saves its Bridge Protocol Data Unit

(BPDU) configuration information.

For more details, refer to “Specifying the bridge maximum aging time for all xSTP” on

page 344.

8. Issue the <bna-config-cmd> RPC to save the running config file to the startup config file and

save the configuration changes.
