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 RPC to configure the node in the
urn:brocade.com:mgmt:brocade-interface namespace.
2. Under the node, include the node from the
urn:brocade.com:mgmt:brocade-xstp namespace.
3. Under the node, include the , or node element.
4. Under the , or node, include the node element.
5. Under the node, include the following leaf elements.
a. In the element, specify the VLAN ID.
b. In the leaf element and specify the time range in seconds for the interval
between the hello BPDUs sent on an interface.
