www.dell.com | support.dell.com In addition, packets assigned to various VLANs are transmitted along different paths within Multiple Spanning Trees Regions (MST regions). Regions are one or more interconnected Multiple Spanning Tree bridges with identical MSTP configuration. In configuring an MST, the MST region to which your device belongs is defined. A configuration consists of the name, revision and region to which your device belongs. To open the MSTP Settings page, click Switch →Spanning Tree →MSTP Region Configuration in the tree view. Figure 7-24. MSTP Settings The MSTP Settings page contains the following fields divided into two sections: Region Name (1-32) - 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. 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. The default field value is 20. IST Master - Indicates the Internal Spanning Tree Master ID. The IST Master is the root of the specified instance and its instance is 0. Instance ID - Specifies the ID of the spanning tree instance. The field range is 1-15. Included VLANs- Maps the selected VLANs to the selected instance. Every VLAN belongs to one instance only. Bridge Priority (0-61440) - Specifies the device priority for the selected spanning tree instance. 290 Configuring Switch Information
