Multiple Instance Spanning-Tree Operation Configuring MSTP MSTP Configuration Overview This section describes the general steps for configuring MSTP via the CLI, assuming that you have already determined the VLANs you want MSTP to use (see "Planning an MSTP Application" on page 4-17). A description of each MSTP command syntax is provided in the following sections. 1. Configure MSTP global parameters. This step involves configuring the following: • Required parameters for MST region identity: Region Name: spanning-tree config-name Region Revision Number: spanning-tree config-revision • Optional MSTP parameter changes for region settings: ProCurve recommends that you leave these parameters at their default settings for most networks. See the "Caution" on page 4-9. - The maximum number of hops before the MSTP BPDU is discarded: spanning-tree max-hops (default: 20) - Force-Version operation: spanning-tree force-version - Forward Delay: spanning-tree forward-delay - Hello Time (if it is the root device): spanning-tree hello-time - Maximum age to allow for STP packets before discarding: spanning-tree maximum-age - Device spanning-tree priority. Specifies the priority value used along with the switch MAC address to determine which device is root. The lower a priority value, the higher the priority. spanning-tree priority 2. Configure per port parameters. ProCurve recommends that you use the default settings for these parameters and apply changes on a per-port basis only where a non-default setting is clearly indicated by the circumstances of individual links. Other features you might consider include BPDU Filtering or BPDU Protection-these provide additional per-port control over spanning-tree operations and security on the switch. 4-19
