CCNA綜合實驗(一)：實驗實作(Ⅰ)

實驗拓撲：

	116-119/30	96-111/28	128-191/26	192-255/26
裝置名稱	接口名稱	配置設定位址以及子網路遮罩
	S0/0	192.168.1.113/30 252
F0/0	192.168.1.33/27 224
Loopback0	192.168.1.10/29 248
R2		192.168.1.114/30 252

		192.168.1.118/30 252
	192.168.1.65/27 224
	192.168.1.30/29 248
SW1		192.168.1.98/28 240
SW2		192.168.1.99/28 240
SW3		192.168.1.100/28 240

二、可以使用Cisco Packet Tracer 或者GNS模拟器，若使用GNS3需要使用路由器來模拟交換機，使用VPCS來模拟主機可以檢視這篇文章

這裡使用Cisco Packet Tracer 6.0完全可以完成

三、實驗操作

中繼要求：三台交換機之間連接配接封裝Trunk ，采用802.1Q的方式封裝，SW1為VTP Server；SW2和SW3為VTP Client；VTP 域名為CCNA，VTP密碼cisco，VTP version 2

STP要求：SW2為VLAN X1的跟橋，SW3為VLAN X2的跟橋，注意觀察接口的狀态，哪個接口是阻塞狀态？

STP特性：與PC直連的接口設定Portfast .

VLAN：VLAN 1為管理VLAN ，要求給三個交換機都配置管理位址，并且遠端可以進行telnet登入；建立VLAN X1和VLAN X2名稱分别為NetServer 、TFTPServer

注意：三台交換機不能直接兩兩相連成環狀，由于還未配置生成樹協定，會導緻環路生成。

配置VTP

SW1(config)#vtp domain ccna

Changing VTP domain name from NULL to ccna

SW1(config)#vtp mode server

Device mode already VTP SERVER.

SW1(config)#vtp version 2

SW1(config)#vtp password cisco

SW1(config)#

SW2(config)#vtp domain ccna

SW2(config)#vtp mode client

Setting device to VTP CLIENT mode.

SW2(config)#vtp pass

SW2(config)#vtp password cisco

SW2(config)#

SW3(config)#vtp domain ccna

SW3(config)#vtp mode client

SW3(config)#vtp pass

SW3(config)#vtp password cisco

SW3(config)#

配置交換機的管理位址和trunk連接配接

SW1(config)#int vlan 1

SW1(config-if)#ip add 192.168.1.98 255.255.255.240

SW1(config-if)#no shut

SW1(config-if)#

%LINK-5-CHANGED: Interface Vlan1, changed state to up

SW2(config)#int vlan 1

SW2(config-if)#ip add 192.168.1.99 255.255.255.240

SW2(config-if)#no shut

SW2(config-if)#

SW3(config)#int vlan 1

SW3(config-if)#ip add 192.168.1.100 255.255.255.240

SW3(config-if)#no shut

SW3(config-if)#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

SW2(config-if-range)#

SW3(config)#int range f0/1-2

SW3(config-if-range)#sw

SW3(config-if-range)#switchport mode trunk

SW3(config-if-range)#

劃分VLAN

SW1(vlan)#vlan 11 name NetServer

VLAN 11 added:

Name: NetServer

SW1(vlan)#vlan 12 name TFTPServer

VLAN 12 added:

Name: TFTPServer

SW1(vlan)#

将與PC直接相連的接口設為PortFast，并劃分到相應的VLAN中

SW1(config)#int range f0/4-12

SW1(config-if-range)#sw mode access

SW1(config-if-range)#sw access vlan 11

SW1(config-if-range)#int range f0/13-24

SW1(config-if-range)#sw access vlan 12

SW1(config-if-range)#

SW2(config)#int range f0/4-12

SW2(config-if-range)#sw mode acc

SW2(config-if-range)#sw acc vlan 11

SW2(config-if-range)#int range f0/13-24

SW2(config-if-range)#sw acc vlan 12

SW3(config)#int range f0/4-24

SW3(config-if-range)#sw mode acc

SW3(config-if-range)#sw acc vlan 12

設定SW2為VLAN X1的跟橋，SW3為VLAN X2的跟橋

SW2(config)#spanning-tree vlan 11 root primary

SW3(config)#spanning-tree vlan 12 root primary

檢視配置結果
