关于MST的配置理解和参考,MST就是多生成树协议,可以用MST代替PVST
配置参考:
  Configuring MST
       配置多生成树协议
  This section provides the commands you will need in order to set up the basic configuration of MST on your Catalyst 4000, 6000, or 6500 series switch. Commands and explanations for tuning MST follow     
        这个章节提供了这些命令你将要在Catalyst 4000,6000,或6500系列交换机上建立一个基本的MST配置,命令和解释为了一个基本的MST配置。
the basic configuration section.
  Basic Configuration Follow these steps:
  基本的配置遵循以下的步骤:
  Enable MST on the switch.
  在交换机上使能MST协议
  Use the set spantree mode mst command to set the spanning tree mode on the switch to MST.
  使用设置MST生成树模式命令去甚至生成树模式为MST在交换机上
  Note: To disable MST, another spanning tree protocol, such as PVST+, must be configured.
  注意:要禁用MST,另外一个生成树协议,像PVST+,是必须配置的
  Define the VLAN-to-instance mappings.
  定义一个vlan到实例的映射关系
  Use the set spantree MST instance vlan vlans command to map VLANs to an instance. For example, you would enter the command set spantree MST 10 vlan 1-10,20 to put VLANs 1 to 10 and 20 into        
使用设置生成树MST实例vlan命令去配置映射到vlan实例。例如,你想要进入一个命令行去设置MST生成树 10其中vlan 1-10,20被放入到MST10,通常,全部vlan是被映射到实例 0中。
instance 10. By default, all VLANs are mapped to instance 0.
  Note: Mapping a VLAN to an instance does not take affect until the configuration is committed.
  注意:映射一个vlan到一个实例不影响映射直到配置被指定
  Define the MST configuration name and revision.
  定义一个MST配置名称和版本
  Use the set spantree MST configuration name name and the set spantree MST configuration revision revision number commands to set the configuration and the revision.
  使用设置MST生成树配置名称命名和设置MST生成树配置版本版本号命令行去设置特定的配置和版本。
  Note: Instances 1 to 15 only operate within the MST region. On the boundary of the MST region, MST copies the port state from the IST, which communicates with the other spanning tree protocols such as
        注意:实例 1到 15仅仅运行MST域。在MST区域的边界上,MST获得端口的状态来自IST(IST是一个MST的生成树),IST和其他生成树通讯例如PVST+,CST,和其他MST区域来自
PVST+, CST, and other MST regions to form a loop-free topology. MST-enabled switches only form an MST region if they have a matching VLAN-to-IST mapping, MST configuration name, and MST revision. If
一个自由--循环拓扑。MST使能的交换机仅仅运行在MST区域如果他们有了一个匹配vlan到IST映射,MST配置名称,和MST版本。如果这些树的任何一个失败,这些端口将被标识作为
any of these three fails, the port will be flagged as a boundary port.
一个边界端口。
  Commit the MST configuration to apply it on the switch.
  分配一个MST配置去应用他在交换机上。
  Use the set spantree MST config commit command to commit the MST configuration.
  使用设置MST生成树配置分配命令去分配MST配置
  Note: If you find that you need to discard all edits made since the last commit, you can use the set spantree MST rollback command to undo all edits. If you need to clear changes to the MST configuration   
      注意:如果你发现你需要去丢弃全部的编辑过的自从分配以来,你能够使用全部的MST生成树反转命令去不执行全部的编辑。如果你需要清除变换MST配置通过另外一些会话
made by someone else using another session, use the set spantree MST rollback force command.
,使用设置生成树MST反转强示命令。  
  Tuning MST
        调制MST
  Use the following commands to tune MST on your Catalyst switch.
  使用下面命令去调试MST在Catalyst 交换机
  Setting Priority Per MST Instance
        设置优先级每MST实例
  Because every instance in MST runs independently of the other instances on the switch, every instance can have a different priority on the switch and possibly a different root in the MST region.
  因为每一个实例在MST运行中是独立的区别于其他实例在交换机上,每一个势力能够有一个不同的优先级在交换机和可能有一个不同的根在MST区域。
  To set the priority of a spantree in an instance, use the set spantree priority priority MST instance command.
  去设置生成树的优先级在势力中,使用设置生成树优先级优先MST实例命令。
  Setting Path Costs on a Specific Port
        设置路径花费在指定的端口
  For every port, MST can use either the standard cost for the port or it can assign a different cost using the set spantree port instance cost mode port cost cost MST instance command. You can use this      
  从每一个端口,MST能够使用标准花费对于一个端口和它能够安排一个不同花费使用设置生成树端口实例花费使得花费开销MST实例命令。你能够使用这个命令去指定多选的
command to specify the alternative path cost for the link being used and to specify which instances will use this alternative path cost.
路径开销为链路被使用和指定那一个势力能够使用这个多选的路径开销。  
  Setting Port Priority on a Specific Port
        设置端口优先级在一个指定端口
  For every port, MST can use either the standard priority for the port or it can assign a different priority with the set spantree port instance riority mode port priority MST instance command. You can use this   
     针对每一个端口,MST能够使用标准的优先级对于一个端口和它安排一个不同优先级在设置生成树端口实例的优先级使得端口优先级MST实例命令,你能够使用这个命令去指
command to specify an alternative priority for a port and to specify which instance will use the alternative priority.
定一个多选的优先级为一个端口和去指定那一个实例将能够使用多选的优先级。 
  Setting the Link Type on a Port
        在一个端口上 设置链路类型
  Using the set spantree MST link-type mode port link-type command, you can configure the link type in any of the following three ways.
  使用一个设备MST生成树链路类型使得端口链路类型命令,你能够配置特定的链路类型在以下的三种方法里。
  Auto - The switch will autodetect the link type for MST.
  自动---交换机将自动检测端口类型为MST
  Point-to-point - The link is a point-to-point link to another device. For example, you could have a 10 Gigabit link to another Catalyst switch.
  点到点---这种链路类型是一个点到点连接到另外一个设备。例如,你将能够有一个10Gb链路连接另外一个Catalyst交换机
  Shared - The link is a shared segment and can contain more than one device. An example of such a link would be a 10 Mb hub.
  共享的----这种链路类型是共享分段和能够包含超过一个设备。一个实例就如一个10M的hub链路。
  Verifying MST Operation
        检验MST运行
  This section provides commands you can use to confirm your configuration is working properly. Examples of output from these commands are explained in the Troubleshooting section.
  这个章节提供的命令你能够去确定你的配置是恰当的在运行中。展示一些实例从这些命令被解释在排查揪错那一章节。
  Certain show commands are supported by the Output Interpreter, which allows you to view an analysis of show command output.
  某个显示命令被支持通过出端口解释器,这个解释器允许你去观察一个分析器的显示命令输出。
  show spantree MST instance active - Use this command to see the MST information on an instance. The addition of the keyword "active" shows only the active ports in the chosen instance.
  显示生成树MST实例激活---使用这些命令去看MST消息在一个实例上。一个额外的关键字“激活”仅仅显示这个激活端口在被选择的实例。
  Show spantree MST mod/port - This command shows you information on the spanning tree state for a specified port when running MST.
  显示MST生成树模式/端口----这个命令显示你的信息在生成树状态为一个指定端口当这个端口运行MST。
  show spantree MST configuration - Use this command to see information about the MST configuration on the switch.
  显示MST生成树配置----使用这个命令去看MST配置在交换机上的信息
  Show spantree summary MST - This command provides a quick overview of the MST operation.
  显示MST生成树概述----这个命令提供一个MST生成树操作的快速概述
  Show spantree statistics MST mod/port instance - Use this command to see statistics and other information regarding MST operation on the chosen port.
        显示MST生成树统计数模式/端口实例----使用这个命令去看统计数和另外运行在选择端口操作MST评论的消息。
