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 <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 <stp>, <rstp>, <mstp>, <pvst>, or <rpvst> node

element.

4. Under the <stp>, <rstp>, <mstp>, <pvst>, or <rpvst> node, include the <max-age> leaf

element, and specify the bridge maximum aging limit.

<?xml version="1.0" encoding="UTF-8"?>

<edit-config>

</target>

<spanning-tree xmlns="urn:brocade.com:mgmt:brocade-xstp">

<stp>

<max-age>25</max-age>

</stp>

</spanning-tree>

</protocol>

</config>

</edit-config>

</rpc>

<rpc-reply message-id="2011" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

</rpc-reply>

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:

1 2 ... 371 372 373 374 375 376 377 378 379 380 381 ... 621 622
