一、交换机的基本配置
来源:互联网 发布:oppo wlan 移动数据 编辑:程序博客网 时间:2024/05/29 19:17
实验环境:
Cisco 2950交换机1台,Console电缆1根,PC机一台,网线1根。连接如下图所示:
实验步骤:
一、 交换机的带外配置;
1、 在用户模式、特权模式、全局模式、接口模式之间转换;
Switch>enable
Switch#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
Switch(config)#interface FastEthernet 0/1
Switch(config-if)#exit
Switch(config)#exit
Switch#
%SYS-5-CONFIG_I: Configured from console byconsole
Switch#exit
Switch con0 is now available
Press RETURN to get started.
Switch>
2、将交换机的名称改为“student”;
Switch(config)#hostname student
student(config)#
3、 为交换机各个模式设置密码“cisco”;
特权模式下的密码保护
student#enable
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#enable password cisco
student(config)#enable secret cisco1
远程登录口令设置
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#line console 0
student(config-line)#line vty 0 4
student(config-line)#password cisco2
student(config-line)#login
student(config-line)#
student#
4、为交换机制定一个IP地址10.10.10.X/24;
student#config
Configuring from terminal, memory, ornetwork [terminal]?
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#interface vlan 1
student(config-if)#ip address 10.10.10.1255.0.0.0
5、开启交换机的Telnet服务功能,建立Telnet用户admin,口令cisco,并制定只能从10.10.10.y/24登录Telnet服务器;
student#
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#user admin password 0 cisco
student(config)#
6、 查看配置情况;
student>enable
Password:
student#show running-c
Building configuration...
hostname student
!
enable secret 5$1$mERr$q.MA2tj.WFptzvbifq/1i.
enable password cisco
!
!
username admin password 0 cisco
interface Vlan1
ipaddress 10.10.10.1 255.0.0.0
!
!
line con 0
!
line vty 0 4
password cisco2
login
line vty 5 15
login
!
!
End
二、交换机的端口配置:
1、 配置接口的描述、关闭借口、启动接口、配置接口的速度为100Mbps、配置接口工作模式为全双工、配置接口的流程控制;
student#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#interface FastEthernet0/1
student(config-if)#shutdown
%LINK-5-CHANGED: Interface FastEthernet0/1,changed state to administratively down
%LINEPROTO-5-UPDOWN: Line protocol onInterface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol onInterface Vlan1, changed state to down
student(config-if)#
student(config-if)#exit
student(config)#interface FastEthernet0/1
student(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/1,changed state to up
%LINEPROTO-5-UPDOWN: Line protocol onInterface FastEthernet0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol onInterface Vlan1, changed state to up
student(config-if)#speed 100
student(config-if)#duplex full
%LINK-5-CHANGED: Interface FastEthernet0/1,changed state to down
%LINEPROTO-5-UPDOWN: Line protocol onInterface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol onInterface Vlan1, changed state to down
student(config-if)#
2、 配置接口FastEthernet0/10为Access口;
student#
student#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#interface FastEthernet0/10
student(config-if)#switchport mode access
student(config-if)#
3、 配置接口FastEthernet0/12为Trunk口;
student#
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
student(config)#interface fastethernet0/12
student(config-if)#switchport mode Trunk
student(config-if)#end
4、 查看配置情况;
