参考：
Cisco 3548(3524) 交换机：
第一次连接交换机，配置终端参数为:
波特率：9600；数据位：8；停止位：1；奇偶校验：无；流控制：无。
通过串口线连上路由器后，按回车，即可看到配置向导：
(假如不是第一次配置，可以进入超级用户模式后用命令setup调用以下过程)
--- System Configuration Dialog ---
At any point you may enter a question mark ? for help.任何时候可以打?取得帮助
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 [].默认参数在[]中
Continue with configuration dialog? [yes/no]: y继续交互配置吗？回答：y
Enter IP address: 10.1.1.249ip地址
Enter IP netmask: 255.255.255.0子网掩码
Would you like to enter a default gateway address? [yes]: y设置默认网关？y
IP address of default gateway: 10.1.1.254默认网关
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输入超级用户密码
Would you like to configure a Telnet password? [yes]: y
Enter Telnet password: _password输入telnet密码
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]:使用该配置信息吗? y
修改配置：
禁止通过snmp治理：
3548>enable
password:
3548#config term
3548(config)#no snmp community private
3548(config)#no snmp community public
接着配置干道：（确定上级交换机对应端口已设为干道模式）
3548(config)#inter g0/1 选择第一个千兆口
3548(config if)# switchport mode trunk设为干道模式
假如g0/2用于连接另一台3548,也设为干道
3548(config)#inter g0/2
3548(config if)# switchport mode trunk
返回
3548(config if)# exit
3548(config)# exit
3548#
验证： ping 10.1.1.254
配置Vlan数据：
3548#vlan database
3548(vlan)#reset清除以前的配置
3548(vlan)#vtp client设为vtp客户模式
3548(vlan)#vtp domain _domainvtp域是_domain
3548(vlan)#vtp password ********设定vtp域密码
3548(vlan)#exit
3548#
验证：show vtp status显示vlan 数据
show vtp counters
show vlan
同步后看到的vlan数目和名称应与6506上的一致
指定端口到Vlan、配置端口为portfast方式(快速建立连接):
方法1：命令方式
3548#config term
3548(config)#inter f0/1配置1号快速以太网端口
3548(config if)# switchport Access vlan 2指定端口到Vlan 2
3548(config if)# spanning-tree portfast配置端口为portfast方式
3548(config)#inter f0/2配置1号快速以太网端口
3548(config if)# switchport access vlan 2指定端口到Vlan 2
3548(config if)# spanning-tree portfast配置端口为portfast方式
...对每个要设定的端口重复上述步骤。
3548(config if)# exit
3548(config)# exit
3548#
方法1：Web 方式
（预先要安装插件:jre-1-2-2-005-win-i-09-mar-2000.exe）
打开浏览器连接设备：在地址栏输入设备的治理页面url，如3548_9a(10.1.1.248)为：http://10.1.1.249/basiccfg.Html
选中菜单port -> port configure -> 设port fast 为Enable
选中菜单vlan -> vlan membership -> 指定端口所属的Vlan号 可同时指定多个端口

! 注重： 假如把一个端口指定到不存在的VLAN上，3548交换机的VLAN同步会异常，此时应该为正确VLAN并重新“配置Vlan数据”
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
选中设备(而不是单个端口)，点击save configure按钮。

3548_9A#show run
