CONFIGURING ETHERCHANNEL

CONFIGURING ETHERCHANNEL

Configure PAgP on S1 and S3.  

S1(config)# interface range f0/3-4

S1(config-if-range)# channel-group 1 mode desirable

S1(config-if-range)# no shutdown

S3(config)# interface range f0/3-4

S3(config-if-range)# channel-group 1 mode auto

S3(config-if-range)# no shutdown

Pengujian S1 dan S3

S1# show run interface f0/3

S1# show interfaces f0/3 switchport

S1# show etherchannel summary

Configure trunk ports.

S1(config-if)# switchport mode trunk

S1(config-if)# switchport trunk native vlan 99

S3(config)# interface port-channel 1

S3(config-if)# switchport mode trunk

S3(config-if)# switchport trunk native vlan 99

Configure LACP between S1 and S2.

S1(config)# interface range f0/1-2

S1(config-if-range)# switchport mode trunk

S1(config-if-range)# switchport trunk native vlan 99

Port Security, Telnet dan SSH pada perangkat Cisco

PORT SECURITY

1. Password Console

Router(config)#username admin password cisco

Router(config)#line console 0

Router(config-line)#login local

Router(config-line)#exit

Router(config)#exit

Router#exit

User Access Verification

Username: admin

2. Password Privilege

Contoh

Router>enable

Router#configure terminal

Router(config)#enable password cisco

Router(config)#enable secret class

Router(config)#exit

Router#

Router#disable

Router>

Router>enable

Password:

TELNET

Contoh

Router(config)#hostname Router1

Router1(config)#line vty 0 4

Router1(config-line)#password aman

Router1(config-line)#login

Mencoba login telnet

PC>telnet 10.10.2.1

Trying 10.10.2.1 …Open

User Access Verification

Password:

R1>

SSH

Contoh

Router1(config)#username cisco password ccna

Router1(config)#ip domain name cisco.com

Router1(config)#crypto key generate rsa

The name for the keys will be: s1.cisco.com

How many bits in the modulus [512]: 1024

% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]

Router1(config)#line vty 0 15

Router1(config-line)#transport input ssh

Router1(config-line)#login local

Router1(config-line)#ip ssh version 2

Router1(config)#exit

Pengujian

PC>ssh –l cisco 10.10.2.1

Cara Buat Flashdisk Installer Windows untuk BIOS Legacy dan UEFI

AYO BUAT INSTALLER WINDOWS DENGAN MUDAH

CARA MEMBUAT INSTALLER WINDOWS DENGAN FLASDISK (DISKPART)

Dapat digunakan untuk instalasi PC/Laptop BIOS biasa ataupun UEFI

Masukkan Flashdisk ke port USB lalu Buka CMD (Command Prompt)

• ·  C:\Windows\System32> diskpart                                Tekan Enter
• ·  C:\Windows\System32> list disk                                 Tekan Enter

Lihat nomor disk untuk flashdisk yang dapat ditandai dari besar kapasitasnya

Terdapat Disk 0, Disk 1 Disk 2 dan seterusnya (tergantung jlh partisi komputer)

Misalnya flashdisk terdeteksi disk 3 maka selanjutnya select disk .... diisi 3

• ·  C:\Windows\System32> select disk 3                         Tekan Enter
• ·  C:\Windows\System32> clean                                     Tekan Enter
• ·  C:\Windows\System32> create partition primary      Tekan Enter
• ·  C:\Windows\System32> active                                    Tekan Enter
• ·  C:\Windows\System32> format fs=fat32 quick          Tekan Enter

Lanjutkan dengan meng-copy seluruh file  dari CD Installer Windows ke flashdisk

Flashdisk installer siap digunakan ......
