Specifying bridge forward delay on a per-VLAN basis
Using PVST or Rapid PVST, you may specify the forward delay for a specific VLAN. If the VLAN
parameter is not provided, the priority value is applied globally for all per-VLAN instances. But for
the VLANs which have been configured explicitly, the per-VLAN configuration takes precedence over
the global configuration.
The VLAN ID value can be 1 through 3583. VLAN IDs 3584 through 4094 are internally-reserved
VLAN IDs.
The range is 4 through 30 seconds. The default is 15 seconds. The following relationship should be
kept:
2*(forward_delay - 1)>=max_age>=2*(hello_time + 1)
To specify the bridge forward delay 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 bridge forward delay.
