1．設定主機名/系統名 switch(config)# hostname “hostname” switch(enable) set system name name-string
2．設定登入口令 switch(config)# enable password level 1 password switch(enable) set password
switch(enable) set enalbepass
3．設定遠端訪問 switch(config)# inte***ce vlan 1
switch(config-if)# ip address ip-address netmask
switch(config-if)# ip default-gateway ip-address switch(enable) set inte***ce sc0 ip-address netmask broadcast-address
switch(enable) set inte***ce sc0 vlan
switch(enable) set ip route default gateway
4．啟用和瀏覽CDP資訊 switch(config-if)# cdp enable
switch(config-if)# no cdp enable switch(enable) set cdp {enable|disable} module/port
5、給交換機配置使能密碼，進入特權模式時需要輸入密碼才能進入，避免裝置可以被其他人員使用。cisco-sw1(config)#enable secret ciscoswitchps:secret表示密碼用的密文
6、交換機配置VLAN，並給將埠加入到該VLAN：cisco-sw1(config)#vlan 2cisco-sw1(config-vlan)#name testcisco-sw1(config-vlan)#exitcisco-sw1(config)#interface fastEthernet 0/1cisco-sw1(config-if)#switchport mode accesscisco-sw1(config-if)#switchport access vlan 2
7、進入交換機某一埠switch> enableswitch＃configure terminalswitch(conf)# interface fastehernet 0/1switch(conf-if)#
8、show：檢視命令，交換機的所有配置和其它相關資訊都需要透過show命令檢視。switch> enableswitch# show version 察看系統中的所有版本資訊switch#show vlan id 1 檢視交換機有關vlan配置資訊switch#show running-configure 檢視交換機當前起作用的配置資訊switch#show interface fastethernet 0/1 察看交換機1 介面具體配置和統計資訊switch#show mac-address-table 檢視mac地址轉發表
9、交換機恢復出廠switch> enableswitch# erase startup-configureswitch# reload
10、telnet 遠端登入設定：switch>enswitch＃configure terminalswich(conf)#enable password cisco 以cisco 為特權模式密碼swich(conf)#interface vlan 1 以vlan 1埠作為遠端登入的介面，其他埠亦可swich(conf-if)#ip address 192.168.1.1 255.255.255.0swich(conf-if)#no shutswich(conf-if)#exitswich(conf)line vty 0 4 設定0-4 個使用者可以telnet 遠端登陸swich(conf-line)#password 123456swich(conf-line)#login
11、SSH遠端登入設定：Switch#conf tEnter configuration commands, one per line. End with CNTL/Z.Switch(config)#hostname cisco-sw1
交換機重新命名cisco-sw1(config)#ip domain-name cisco.com
配置域名cisco-sw1(config)#line vty 0 4cisco-sw1(config-line)#transport input ssh
登入方式為SSHcisco-sw1(config-line)#exitcisco-sw1(config)#crypto key generate rsa
