上一篇给大家讲到了cisco交换机的基本操作命令,趁端午节放假前,把cisco交换机的简单配置分享一下并预祝一下各位“端午节快乐”!Ok,要进行交换机的配置,首先就得进入交换机的全局配置模式,在成功连接交换机并且登陆成功进入特权模式下
1、输入进入全局配置模式:
switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. switch(config)# switch(config)# switch(config)#这么简单的一条命令,俺们就进入到全局配置模式了,还记得上一篇中查看端口所查询到的信息中name字段下的值吗?这字段其实代表的是交换机端口的描述信息
2、修改端口描述
switch# switch# switch#conf ter Enter configuration commands, one per line. End with CNTL/Z. switch(config)# switch(config)#int fa0/3 switch(config-if)# switch(config-if)#desc switch(config-if)#description updateDesc switch(config-if)# switch(config-if)#exit switch(config)#exit switch# switch#show inter switch#show interfaces statu switch#show interfaces status Port Name Status Vlan Duplex Speed Type Fa0/1 connected 1 a-full a-100 10/100BaseTX Fa0/2 h3c2.250 connected trunk a-full a-100 10/100BaseTX Fa0/3 updateDesc notconnect 1 auto auto 10/100BaseTX Fa0/4 connected 1 a-full a-100 10/100BaseTX Fa0/5 h3c-2.200 connected 1 a-full a-100 10/100BaseTX Fa0/6 notconnect 1 auto auto 10/100BaseTX
3、修改端口Vlan
switch# switch# switch#conf t Enter configuration commands, one per line. End with CNTL/Z. switch(config)# switch(config)#int fa0/3 switch(config-if)# switch(config-if)#sw acc vl 2 switch(config-if)# switch(config-if)#exit switch(config)# switch(config)#exit switch# switch#show inter statu Port Name Status Vlan Duplex Speed Type Fa0/1 connected 1 a-full a-100 10/100BaseTX Fa0/2 h3c2.250 connected trunk a-full a-100 10/100BaseTX Fa0/3 updateDesc notconnect 2 auto auto 10/100BaseTX Fa0/4 connected 1 a-full a-100 10/100BaseTX Fa0/5 h3c-2.200 connected 1 a-full a-100 10/100BaseTX Fa0/6 notconnect 1 auto auto 10/100BaseTX
还有一些对端口的简单操作,譬如修改端口的模式,
4、修改端口模式
switch(config-if)#switchport trunk encap dot1q ----------------设置vlan 中继的封装协议 注:dot1q就是 IEEE 802.1Q协议,是vlan的一种封装方式,是公有协议。还有一种trunk协议,是ISL,也是vlan的一种封装方式,不过这是Cisco思科私有协议,其他厂商不能用。 switch(config-if)#switchport mode trunk ------------------------设置端口类型为trunk switch(config-if)#switchport trunk allowed vlan 1,2 ---------设置允许的vlan,默认不用配置,为所有vlan switch(config-if)#switchport trun native vlan 999 ---------------设置trunk口的native vlan
switch(config)# switch(config)#int fa0/3 switch(config-if)# switch(config-if)# switch(config-if)#sw acc vl 1 switch(config-if)# switch(config-if)# switch(config-if)#shutd switch(config-if)#shutdown switch(config-if)# switch(config-if)#exit switch(config)# switch(config)#exit switch# switch#show inter statu Port Name Status Vlan Duplex Speed Type Fa0/1 connected 1 a-full a-100 10/100BaseTX Fa0/2 h3c2.250 connected trunk a-full a-100 10/100BaseTX Fa0/3 updateDesc disabled 1 auto auto 10/100BaseTX Fa0/4 connected 1 a-full a-100 10/100BaseTX
switch#conf t Enter configuration commands, one per line. End with CNTL/Z. switch(config)# switch(config)#int fa0/3 switch(config-if)# switch(config-if)#no shut switch(config-if)#no shutdown switch(config-if)# switch(config-if)#exit switch(config)# switch(config)#exit switch# switch#show inter statu Port Name Status Vlan Duplex Speed Type Fa0/1 connected 1 a-full a-100 10/100BaseTX Fa0/2 h3c2.250 connected trunk a-full a-100 10/100BaseTX Fa0/3 updateDesc notconnect 1 auto auto 10/100BaseTX Fa0/4 connected 1 a-full a-100 10/100BaseTX
