cisco思科怎么配置STP

  思科公司已成為公認的世界網(wǎng)絡互聯(lián)解決方案的領先廠商,該公司出產(chǎn)的一系列路由器更是引領世界,那么你知道cisco思科怎么配置STP嗎?下面是學習啦小編整理的一些關于cisco思科怎么配置STP的相關資料,供你參考。

  cisco思科配置STP的方法:

  SwA(config)#spanning-tree vlan 1 root primary

  SwA(config)#spanning-tree vlan 2 root primary

  v配置SwB在VLAN 3和4中優(yōu)先級為4096

  SwB(config)#spanning-tree vlan 3 priority 4096

  v配置SwA為VLAN 1和2的根網(wǎng)橋

  SwB(config)#spanning-tree vlan 4 priority 4096

  v查看配置結(jié)果

  SwB# show spanning-tree

  v配置交換機 C上連接主機的端口為速端口

  SwC(config)#interface range fastEthernet 0/1 - 20

  SwC(config-if-range)#spanning-tree portfast

  %Warning: portfast should only be enabled on ports connected to a single

  host. Connecting hubs, concentrators, switches, bridges, etc... to this

  interface when portfast is enabled, can cause temporary bridging loops.

  Use with CAUTION

  %Portfast will be configured in 20 interfaces due to the range command

  but will only have effect when the interfaces are in a non-trunking mode.

  v在交換機C上配置上行速鏈路

  SwC(config)#spanning-tree uplinkfast

  v配置了上行速鏈路后查看生成樹信息

  SwC#show spanning-tree
