思科交換機的基本配置
隨著Internet的高速發展,網路規模不斷膨脹,對於從事網路專業的學生熟練掌握路由器和交換機的配置已顯得十分重要。接下來是小編為大家收集的方法，希望能幫到大家。
的方法
一、交換機的基本配置
Author：chenchao in ZJNU
從本篇文章開始，將連載大概8-9篇自己學習交換與路由的實驗報告，但是怕自己能力不行，會出現錯誤，所以，先載兩篇文章，依次為：交換機的基本配置;路由器基本配置。本篇為交換機的基本配置，使用的模擬軟體是Cisco的一款免費軟體：Cisco Packet Tracer。想學習的可以在百度自行下載。
下面開始附上實驗過程：
實驗環境：
Cisco 2950交換機1臺，Console電纜1根，PC機一臺，網線1根。連線如下圖所示：
實驗步驟：
一、 交換機的帶外配置;
1、 在使用者模式、特權模式、全域性模式、介面模式之間轉換;
Switch>enable
Switch#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
Switchconfig#interface FastEthernet 0/1
Switchconfig-if#exit
Switchconfig#exit
Switch#
%SYS-5-CONFIG_I: Configured from console byconsole
Switch#exit
Switch con0 is now available
Press RETURN to get started.
Switch>
2、將交換機的名稱改為“student”;
Switchconfig#hostname student
studentconfig#
3、 為交換機各個模式設定密碼“cisco”;
特權模式下的密碼保護
student#enable
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#enable password cisco
studentconfig#enable secret cisco1
遠端登入口令設定
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#line console 0
studentconfig-line#line vty 0 4
studentconfig-line#password cisco2
studentconfig-line#login
studentconfig-line#
student#
4、為交換機制定一個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.
studentconfig#interface vlan 1
studentconfig-if#ip address 10.10.10.1255.0.0.0
5、開啟交換機的Telnet服務功能，建立Telnet使用者admin，口令cisco，並制定只能從10.10.10.y/24登入Telnet伺服器;
student#
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#user admin password 0 cisco
studentconfig#
6、 檢視配置情況;
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、交換機的埠配置：
1、 配置介面的描述、關閉藉口、啟動介面、配置介面的速度為100Mbps、配置介面工作模式為全雙工、配置介面的流程控制;
student#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#interface FastEthernet0/1
studentconfig-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
studentconfig-if#
studentconfig-if#exit
studentconfig#interface FastEthernet0/1
studentconfig-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
studentconfig-if#speed 100
studentconfig-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
studentconfig-if#
2、 配置介面FastEthernet0/10為Access口;
student#
student#configure terminal
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#interface FastEthernet0/10
studentconfig-if#switchport mode access
studentconfig-if#
3、 配置介面FastEthernet0/12為Trunk口;
student#
student#configure t
Enter configuration commands, one perline. End with CNTL/Z.
studentconfig#interface fastethernet0/12
studentconfig-if#switchport mode Trunk
studentconfig-if#end
4、 檢視配置情況;

interface FastEthernet0/2
!
interface FastEthernet0/9
!
interface FastEthernet0/10
switchport mode access
