Intel® Blade Server Ethernet Switch Module IXM5414E 251
IEEE 802.1w configuration example
This section shows you how to configure the Intel® Blade Server Ethernet Switch Module
IXM5414E to support rapid reconfiguration of the spanning tree topology. The IEEE 802.1w
support specified in IEEE 802.1s defines a new configuration algorithm and protocol that provide
significantly faster reconfiguration of the spanning tree than the original algorithm and protocol
defined in the base IEEE 802.1D standard. While the old and new protocols will successfully
interoperate, the IEEE 802.1 standards committee recommends the use of the new protocol.
Configuration of the switch to support IEEE 802.1w is simple. In normal operation, the bridge
timers are not used to control reconfiguration, and the default values should be adequate. Bridge and
port priorities and path costs are still required, and are configured as shown for IEEE 802.1D.
Configure the switch to use rapid reconfiguration.
config spanningtree forceversion 802.1w
To disable support for rapid reconfiguration.
