      cisco思科怎么配置STP

        思科公司已成為公認(rèn)的世界網(wǎng)絡(luò)互聯(lián)解決方案的領(lǐng)先廠商,該公司出產(chǎn)的一系列路由器更是引領(lǐng)世界,那么你知道cisco思科怎么配置STP嗎?下面是學(xué)習(xí)啦小編整理的一些關(guān)于cisco思科怎么配置STP的相關(guān)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
