Cisco交换机range命令的使用，批处理改变多个端口设置

wendu

　　在Cisco交换机里面有一个非常有用的命令，开始刚学习的时候不知道，走了不少弯路。这个命令可以用一次改变多个端口的设置。换句话说，如果你需要在交换机的许多个端口上进行相同的操作，不需要一个一个端口的设置，只需要一个命令就可以了。这个命令就是“range”，例如下：
　　S1(config)#interface range fastEthernet 0/1-24
　　S1(config-if-range)#no shutdown
　　//注意：从这儿开始是交换机改变设置时自动显示的端口变化情况
　　%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up
　　%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
　　%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
　　%LINK-5-CHANGED: Interface FastEthernet0/2, changed state to up

　　%LINK-5-CHANGED: Interface FastEthernet0/19, changed state to down
　　%LINK-5-CHANGED: Interface FastEthernet0/20, changed state to down
　　%LINK-5-CHANGED: Interface FastEthernet0/21, changed state to down
　　%LINK-5-CHANGED: Interface FastEthernet0/22, changed state to down
　　%LINK-5-CHANGED: Interface FastEthernet0/23, changed state to down
　　%LINK-5-CHANGED: Interface FastEthernet0/24, changed state to down
　　S1(config-if-range)#
　　还可以用show running...验证下，很好玩。
