Spanning tree configuration and management

Specifying the bridge maximum aging time for all xSTP
For any spanning tree mode (STP, RSTP, MSTP, PVST, or Rapid PVST), use this procedure to control
the maximum length of time that passes before an interface saves its Bridge Protocol Data Unit
(BPDU) configuration information.
When configuring the maximum aging time, the max-age setting must be greater than the
hello-time setting. The range is 6 through 40 seconds. The default is 20 seconds. The following
relationship should be kept:
2*(forward_delay - 1)>=max_age>=2*(hello_time + 1)
To specify the bridge maximum aging time, 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 leaf
element, and specify the bridge maximum aging limit.

Specifying the bridge maximum aging time
Using PVST, or Rapid PVST, use this procedure on a per VLAN basis to control the maximum length
of time that passes before an interface saves its Bridge Protocol Data Unit (BPDU) configuration
information. For the VLANs which have been configured explicitly, the per-VLAN configuration takes
precedence over the global configuration.
When configuring the maximum aging time, the max-age setting must be greater than the
hello-time setting. The range is 6 through 40 seconds. The default is 20 seconds. The following
relationship should be kept:
