MSTP Settings The Multiple Spanning Tree Protocol (MSTP) supports multiple instances of Spanning Tree to efficiently channel VLAN traffic over different interfaces. MSTP is compatible with both RSTP and STP; a MSTP bridge can be configured to behave entirely as a RSTP bridge or a STP bridge. To display the MSTP Settings page, click Switching > Spanning Tree > MSTP Settings in the tree view. Figure 7-45. MSTP Settings The MSTP Settings page contains the following fields divided into two sections, Global Settings and Instance Settings: • Region Name (1-32 characters) - Specifies a user-defined MST region name. • Revision (0-65535) - Specifies unsigned 16-bit number that identifies the revision of the current MST configuration. The revision number is required as part of the MST configuration. Default is 0. • Max Hops (1-40) - Specifies the total number of hops that occur in a specific region before the BPDU is discarded. Once the BPDU is discarded, the port information is aged out. Default is 20. • Instance ID - Specifies the ID of the spanning tree instance. The field range is 1-15, and default is 1. 318 Configuring Switching Information
