Cisco 3548(3524) 交換機：
第一次連接交換機，配置終端參數為:
波特率：9600；數據位：8；停止位：1；奇偶校驗：無；流控制：無。
通過串口線連上路由器后，按回車，即可看到配置向導：
--- System Configuration Dialog ---
At any point you may enter a question mark ? for help.任何時候可以打?取得幫助
Use ctrl-c to abort configuration dialog at any prompt.按Ctrl-C可以取消并退出
Default settings are in square brackets [].默認參數在[]中
Continue with configuration dialog? [yes/no]: y繼續交互配置嗎？回答：y
Enter IP address: 10.1.1.249ip地址
Enter IP netmask: 255.255.255.0子網掩碼
Would you like to enter a default gateway address? [yes]: y設置默認網關？y
IP address of default gateway: 10.1.1.254默認網關
Enter host name [3548_9A]:
The enable secret is a one-way cryptographic secret used
instead of the enable password when it exists.
Enter enable secret: _password輸入超級用戶密碼
Would you like to configure a Telnet password? [yes]: y
Enter Telnet password: _password輸入telnet密碼
Would you like to enable as a cluster command switch? [yes/no]: n集群模式？n
The following configuration command script was created:已建立以下配置信息
ip subnet-zero
interface VLAN1
ip address 10.1.1.249 255.255.255.0
ip default-gateway 10.1.1.254
enable secret 5 $1$biZ3$AOLb9cMTtBwMtGB9lyBzr.
line vty 0 15
password _domainwlzx
snmp community private rw
snmp community public ro
!
end
Use this configuration? [yes/no]:使用該配置信息嗎? y
修改配置：
禁止通過snmp管理：
3548>enable
password:
3548#config term
3548(config)#no snmp community private
3548(config)#no snmp community public
接著配置干道：（確定上級交換機對應端口已設為干道模式）
3548(config)#inter g0/1 選擇第一個千兆口
3548(config if)# switchport mode trunk設為干道模式
如果g0/2用于連接另一臺3548,也設為干道
3548(config)#inter g0/2
3548(config if)# switchport mode trunk
返回
3548(config if)# exit
3548(config)# exit
3548#
驗證： ping 10.1.1.254
配置Vlan數據：
3548#vlan database
3548(vlan)#reset清除以前的配置
3548(vlan)#vtp client設為vtp客戶模式
3548(vlan)#vtp domain _domainvtp域是_domain
3548(vlan)#vtp password ********設定vtp域密碼
3548(vlan)#exit
3548#
驗證：show vtp status顯示vlan 數據
show vtp counters
show vlan
同步后看到的vlan數目和名稱應與6506上的一致
指定端口到Vlan、配置端口為portfast方式(快速建立連接):
方法1：命令方式
3548#config term
3548(config)#inter f0/1配置1號快速以太網端口
3548(config if)# switchport access vlan 2指定端口到Vlan 2
3548(config if)# spanning-tree portfast配置端口為portfast方式
3548(config)#inter f0/2配置1號快速以太網端口
3548(config if)# switchport access vlan 2指定端口到Vlan 2
3548(config if)# spanning-tree portfast配置端口為portfast方式
...對每個要設定的端口重復上述步驟。
3548(config if)# exit
3548(config)# exit
3548#
方法1：Web 方式
（預先要安裝插件:jre-1-2-2-005-win-i-09-mar-2000.exe）
打開瀏覽器連接設備：在地址欄輸入設備的管理頁面url，如3548_9a(10.1.1.248)為：http://10.1.1.249/basiccfg.html
選中菜單port -> port configure -> 設port fast 為Enable
選中菜單vlan -> vlan membership -> 指定端口所屬的Vlan號 可同時指定多個端口
! 注意： 如果把一個端口指定到不存在的VLAN上，3548交換機的VLAN同步會異常，此時應該為正確VLAN并重新“配置Vlan數據”
保存配置信息：
方法1：命令方式
3548# write ( 或 copy running-config startup-config )
方法1：Web 方式
選中設備(而不是單個端口)，點擊save configure按鈕。
3548_9A#show run
