1-15z Loop guardz TC-BPDU attack guardz BPDU packet dropProtocols and StandardsMSTP is documented in:z IEEE 802.1D: spanning tree protocolz IEEE 802.1w: rapid spanning tree protocolz IEEE 802.1s: multiple spanning tree protocolMSTP Configuration Task ListBefore configuring MSTP, you need to know the position of each device in each MSTI: root bridge orleave node. In each MSTI, one, and only one device acts as the root bridge, while all others as leafnodes.Complete these tasks to configure MSTP:Task RemarksEnabling MSTPRequiredTo prevent network topology jitter caused byother related configurations, you arerecommended to enable MSTP after otherrelated configurations are performed.Configuring an MST Region RequiredSpecifying the Current Switch as a RootBridge/Secondary Root Bridge RequiredConfiguring the Bridge Priority of the CurrentSwitchOptionalThe priority of a switch cannot be changedafter the switch is specified as the rootbridge or a secondary root bridge.Configuring How a Port Recognizes and SendsMSTP Packets OptionalConfiguring the MSTP Operation Mode OptionalConfiguring the Maximum Hop Count of an MSTRegion OptionalConfiguring the Network Diameter of theSwitched NetworkOptionalThe default value is recommended.Configuring the MSTP Time-related Parameters OptionalThe default values are recommended.Configuring the Timeout Time Factor OptionalConfiguring the Maximum Transmitting Rate onthe Current PortOptionalThe default value is recommended.Configuring the Current Port as an Edge Port OptionalConfiguringRoot BridgeSetting the Link Type of a Port to P2P Optional
