---|---|
Spanning Tree Admin Mode | The administrative mode of STP on the device. When enabled, the device participates in the root bridge election process and exchanges Bridge Protocol Data Units (BPDUs) with other switches in the spanning tree to determine the root path costs and maintain topology information. |
Force Protocol Version | The STP version the device uses, which is one of the following:
|
Configuration Name | The name of the MSTP region. Each switch that participates in the same MSTP region must share the same Configuration Name, Configuration Revision Level, and MST-to-VLAN mappings. |
Configuration Revision Level | The revision number of the MSTP region. This number must be the same on all switches that participate in the MSTP region. |
Configuration Digest Key | The 16 byte signature of type HMAC-MD5 (Message-Digest algorithm 5) created from the MST Configuration Table (a VLAN ID-to-MST ID mapping). |
Configuration Format Selector | The version of the configuration format being used in the exchange of BPDUs. |
