Specifying the bridge hello time per VLAN (PVST or RPVST)

For PVST or Rapid PVST, use this procedure to configure the bridge hello time on a per VLAN basis.
The hello time determines how often the switch interface broadcasts BPDUs to other devices. The
range is 1 through 10 seconds. The default is 2 seconds. For the VLANs which have been
configured explicitly, the per-VLAN configuration takes precedence over the global configuration.

When configuring the hello time, the max-age setting must be greater than the hello-time setting.
The following relationship should be kept:

2*(forward_delay - 1)>=max_age>=2*(hello_time + 1)

To specify the bridge hello time for a specific VLAN, perform the following steps.

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.

4. Under the <pvst>, or <rpvst> node, include the <vlan> node element.

5. Under the <vlan> node, include the following leaf elements.

a. In the <id> element, specify the VLAN ID.

b. In the <hello-time> leaf element and specify the time range in seconds for the interval

between the hello BPDUs sent on an interface.
