Two ways to manage the switch
Band Management
Bearer service information management network control information and the user's network via the same logical channel, i.e. consumes bandwidth;
example:
Manage the switch through telnet way. Realize the remote management switches;
Band Management
Bearer service information management network control information and user network different logical channels, is designed to manage switch provides broadband;
example:
Connected to the switch console port; PC serial port connection switch; may be connected to the switch through the HyperTerminal on the PC;
Basic switch configuration information
Command line switches are:
Switch> #用户模式
Switch# #特权模式
Switch(config)# #全局配置模式
Switch(config-if)# #端口模式 if是interface的缩写；Command line switch:
进入特权模式（en/enable）
进入全局配置模式（conf t）config terminal
进入交换机端口视图模式int f 0/1
返回到上级模式（exit）
从全局以下模式返回到特权模式（end）Use telnet way configuration switch related experiments
Technical principles
- Switch configuration management ip address (ip address settings for the computer and the switch management IP address in the same network segment)
- In the switcher, the IP address of the switch only for login management, configuration management, if there is no IP address, the switch can only be used for local control console port configuration and management;
- By default, all ports of a switch belong vlan1, it switches automatically created and officials. Each vlan only one active management address, so before setting management address Layer 2 switches should first select vlan1 the interface, and then use the IP address configuration command to set the IP address management.
- Telnet user to set a user name and login password;
- Setting switch mode privileged mode password and login password; can improve the safety switch;

New packet Tracer topology
Configure the switch ip address management
Switch(config)# int vlan 1 #登录到vlan1的接口模式
Switch(config)# ip address **IP** **submask** #ip地址后面加子网掩码Configure the user logon password
Switch(config)# enable password ****** //设置进入特权模式的密码
Switch(config)# line vty 0 4
Switch(config-line)# password ****** #远程登录密码
Switch(config-line)# loginoperating
Open packet tracer, a selection switch 2960, a pc machine;
First select line configuration, the "rs-232" port switch configuration line "console" port is also connected to a router via direct connection pc
- Configure the switch via the PC terminal;
Find the terminal configuration window:
- Configuration command:
Switch>enable #进特权模式
Switch#conf t #进入全局配置模式
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#interface vlan 1 #设置默认接口
Switch(config-if)#ip address 192.168.1.1 255.255.255.0 #配置管理ip地址
Switch(config-if)#no shutdown #开启端口
Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
Switch(config-if)#exit
Switch(config)#enable password 123456
Switch(config)#line vty 0 4
Switch(config-line)#password lhy
Switch(config-line)#login
Switch(config-line)#end
