要求1

R2配置

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#host R2

R2(config)#interface s0/3/0
R2(config-if)#ip add 172.16.1.1 255.255.255.0

R2(config-if)#clock rate  6400

R2(config-if)#no shutdown 

%LINK-5-CHANGED: Interface Serial0/3/0, changed state to down

R2(config-if)#end
-------------------------------------
提示：怎么看设备上是否设置时钟
R2#show controllers s0/3/0

Interface Serial0/3/0
Hardware is PowerQUICC MPC860
DCE V.35, clock rate 2000000
-----
显示 DCE V.35
--------------------------------------

R1配置

Router>en
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hos R1

R1(config)#interface s0/3/0
R1(config-if)#ip add 172.16.1.2 255.255.255.0
R1(config-if)#no sh

R1(config-if)#
%LINK-5-CHANGED: Interface Serial0/3/0, changed state to up

R1(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/3/0, changed state to up

R1(config-if)#inter f0/0
R1(config-if)#ip add 192.168.2.254 255.255.255.0
R1(config-if)#no shu

R1(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up


R1(config)#interface f0/1
R1(config-if)#ip add 192.168.1.254 255.255.255.0
R1(config-if)#no sh


配置好后ping测试
R1(config)#do ping 172.16.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms

SW1配置

Switch>en
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

Switch(config)#interface vlan 1
Switch(config-if)#ip add 192.168.2.253 255.255.255.0
Switch(config-if)#no sh

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)#hostname SW1

PC 和服务器配置IP地址后可以通信正常

要求2

R1 R2 SW1 统一配置

R1(config)#no ip domain-lo

R1(config)#line console 0


R1(config-line)#logging synchronous 

R1(config-line)#exec-timeout 00

R1(config-line)#line vty 0 4


R1(config-line)#logging synchronous 

R1(config-line)#exec-timeout 5 30
R1(config-line)#end

要求3

R1 和 R2 配置

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#enable se
R1(config)#enable secret ciscoccna@

R1(config)#line console 0

R1(config-line)#password ciscoccnp#

R1(config-line)#login 
R1(config-line)#line vty 0 4

R1(config-line)#password ciscoccie$

R1(config-line)#logging 
R1(config)#service password-encryption

R2另外配置

R2(config)#banner motd # this is R2 #
R2(config-if)#description  connect R1
R2(config-if)#end

SW1

SW1(config)#enable secret ciscoccna@
SW1(config)#line console 0
SW1(config-line)#password ciscoccnp#
R2(config)#service password-encryption

要求4

R1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

R1(config)#interface fa0/1
R1(config-if)#no cdp ?
  enable  Enable CDP on interface

R1(config-if)#no cdp enable 
R1(config-if)#END

SW1

SW1# conf t
Enter configuration commands, one per line.  End with CNTL/Z.

SW1(config)#interface range fa0/1-4

SW1(config-if-range)#no cdp enable

要求5

SW1配置

交换机需要配置默认网关，

R1 192.168.2.254 就是交换机的默认网关

SW1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

SW1(config)#ip default-gateway 192.168.2.254
SW1(config)#end
SW1#
%SYS-5-CONFIG_I: Configured from console by console


SW1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
SW1(config)#user
SW1(config)#username ccna
SW1(config)#username ccna password ccna

SW1(config)#username ccnp
SW1(config)#username ccnp password ccnp

SW1(config)#username ccie
SW1(config)#username ccie password ccie

SW1(config)#line vty 0 4

SW1(config-line)#login local 
SW1(config-line)#end
