Membuat jaringan sederhana

Langkah 1: Konfigurasi Router Interfaces

konfigurasi GigabitEthernet 0/0 interface Router ke switch 1.:

Router (config)# interface gigabitethernet 0/0

Router(config-if)# ip address 192.168.10.1 255.255.255.0

Router(config-if)# no shutdown

%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)# description LAN connection to S1 

Router(config-if)# end

%SYS-5-CONFIG_I: Configured from console by console

Router# ping 192.168.10.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.10, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 0/2/8 ms

Langkah 2 : Konfigurasi GigabitEthernet 0/1 interface Router ke switch 2

Router (config)# interface gigabitethernet 0/0

Router(config-if)# ip address 192.168.11.1 255.255.255.0

Router(config-if)# no shutdown

%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)# description LAN connection to S1 

Router(config-if)# end

%SYS-5-CONFIG_I: Configured from console by console

Router# ping 192.168.10.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.10, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 0/2/8 ms

Langkah 3: membuat sistem keamanan memalui line console dan line vty serta enkripsikan password

Switch# configure terminal

Switch(config)# hostname S1

S1(config)# exit

S1#

S1# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

S1(config)# line console 0

S1(config-line)# password letmein

S1(config-line)# login

S1(config-line)# exit

S1(config)# exit

%SYS-5-CONFIG_I: Configured from console by console

S1#

S1# exit

Switch con0 is now available

Press RETURN to get started.

User Access Verification

Password:

S1>

S1> enable

S1# configure terminal

S1(config)# enable password c1$c0

S1(config)# exit

%SYS-5-CONFIG_I: Configured from console by console

S1#

S1# show running-config

S1# config t

S1(config)# enable secret itsasecret

S1(config)# exit

S1#

S1# show run

S1# config t

S1(config)# service password-encryption

S1(config)# exit

Langkah 3: konfigurasi MOTD Banner

S1# config t

S1(config)# banner motd "This is a secure system. Authorized Access Only!"

S1(config)# exit

%SYS-5-CONFIG_I: Configured from console by console

S1#

S1# copy running-config startup-config

Destination filename [startup-config]?[Enter]

Building configuration...
