复习CCNA实验(逐渐添加中)

好久没有玩cisco,很多东西都有点生疏了.今天开始一点点复习,以此文做个复习笔记.实验平台packet tracer 5.1

1.设置主机名

router(config)#hostname r1
r1(config)#

2.设置登陆信息

r1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
r1(config)#banner motd #
Enter TEXT message.  End with the character '#'.
Welcome #

3.设置密码

明文 r1(config)#enable password ccna1

密文 r1(config)#enable secret ccna2

两者同时设定时,密文优先.

console配置密码

r1(config)#line con 0
r1(config-line)#login
r1(config-line)#password ccna3

4.发现协议CDP

查看相关命令

r1#sh cdp ?
  entry      Information for specific neighbor entry
  interface  CDP interface status and configuration
  neighbors  CDP neighbor entries

 

开始CDP协议

RTA(config)#cdp run

5.路由器的配置文件保存,删除,备份

6.建立vlan和vtp

先解释一下交换机的3种端口模式

以太网端口有三种链路类型：Access、Hybrid和Trunk。
Access类型的端口只能属于1个VLAN，一般用于连接计算机的端口；
Trunk类型的端口可以允许多个VLAN通过，可以接收和发送多个VLAN的报文，一般用于交换机之间连接的端口；
Hybrid类型的端口可以允许多个VLAN通过，可以接收和发送多个VLAN的报文，可以用于交换机之间连接，也可以用于连接用户的计算机。
Hybrid端口和Trunk端口在接收数据时，处理方法是一样的，唯一不同之处在于发送数据时：Hybrid端口可以允许多个VLAN的报文发送时不打标签，而Trunk端口只允许缺省VLAN的报文发送时不打标签。

SW-1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
SW-1(config)#vtp domain cisco
Changing VTP domain name from NULL to cisco
SW-1(config)#vtp mode server
Device mode already VTP SERVER.
SW-1(config)#int f0/24
SW-1(config-if)#switchport mode
SW-1(config-if)#switchport mode trunk

SW-1#vlan data
% Warning: It is recommended to configure VLAN from config mode,
  as VLAN database mode is being deprecated. Please consult user
  documentation for configuring VTP/VLAN in config mode.

SW-1(vlan)#vlan 10 name vlan10
VLAN 10 added:
    Name: vlan10
SW-1(vlan)#exit

SW-1(config)#int f0/1
SW-1(config-if)#switchport access vlan 10
SW-1(config-if)#end
%SYS-5-CONFIG_I: Configured from console by console
SW-1#sh vlan
