CONFIGURATION PASSWORD SWITCH,VLAN,TRUNK AND TRUNK ALLOWED



ct3


Langkah Kerja:
  • Buat topologi seperti di bawah ini
  • lalu isikan ip addressnya klik gambar PC>desktop>up configuration, saya menggunakan ip 172.12.10.21 sampai 172.12.10.26
ct1
  • kemudian saya akan membuat 3 password antara lain:
  • Enable secret, fungsinya untuk proteksi sebelum masuk mode privileged
  • Password console, fungsinya untuk proteksi sebelum masuk user mode
  • Password Telnet /VTY, fungsinya sama seperti password console,bedanya kalo password vty via jaringan. cara settingnya klik switch(S2)>cli
  • kemudian ketik “enable” untuk masuk mode privileged
S2>enable
S2#
  • lalu ketik “conf t” untuk masuk global configuration
S2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
  • langsung saja, untuk enable secret passwordnya ciscosec, console passwordnya ciscocon, yang terakhir telnet/vty passwordnya ciscovty,lebih jelas liat tulisan di bawah
S2(config)#enable secret ciscosec
S2(config)#exit
S2(config)#line console 0
S2(config-line)#password ciscocon
S2(config-line)#exec-timeout 5 0
S2(config-line)#login
S2(config-line)#exit
S2(config)#line vty 0 4
S2(config-line)#password ciscovty
S2(config-line)#exec-timeout 5 0
S2(config-line)#login                                                                                                                                  
S2(config-line)#exit
  • ketikan “service password-encryption” untuk mengenkripsi password lebih jelasnya liat tulisan dibawah
S2(config)#service password-encryption
S2(config)#
  • lalu kita cek sudah berhasil apa belum dengan cara ketik “do show run”
S2(config)#do show run

end
  • lakukan konfigurasi seperti di atas pada switch(S1) dan switch(S3)
  • sekarang kita configurasi vlannya caranya klik switch(S1)>cli, masuk ke global configuration, saya akan membuat vlan 10,20,30 kemudian masukan port mana saja yang akan masuk vlan 10,20,30
S2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
S2(config)#vlan 10
S2(config-vlan)#name guru
S2(config-vlan)#exit
S2(config)#vlan 20
S2(config-vlan)#name siswa
S2(config-vlan)#exit
S2(config)#vlan 30
S2(config-vlan)#name tu
S2(config-vlan)#exit
S2(config)#interface fa0/16
S2(config-if)#switchport mode access
S2(config-if)#switchport access vlan 10
S2(config-if)#exit
S2(config)#interface fa0/18
S2(config-if)#switchport mode access
S2(config-if)#switchport access vlan 20
S2(config-if)#exit
S2(config)#interface fa0/6
S2(config-if)#switchport mode access
S2(config-if)#switchport access vlan 30
S2(config-if)#exit
  • lalu kita cek sudah benar atau belum dengan cara ketik “do show vlan brief”
S2(config)#do show vlan brief
VLAN Name Status Ports

1 default active Fa0/1,Fa0/2,Fa0/3,Fa0/4,
Fa0/5, Fa0/7,Fa0/8, Fa0/9, Fa0/10
Fa0/11,Fa0/12, Fa0/13, Fa0/14

1005 trnet-default active
  • lakukanlah configurasi seperti di atas pada switch(S3)
  • sekarang kita akan mengkonfigurasi trunknya
  • sebelumnya kita harus membuat vlan dulu di switch pusat(S1), jika kita tidak membuat vlan di switch pusat, maka mode trunk akan gagal.
S1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
S1(config)#vlan 10
S1(config-vlan)#name guru
S1(config-vlan)#exit
S1(config)#vlan 20
S1(config-vlan)#name siswa
S1(config-vlan)#exit
S1(config)#vlan 30
S1(config-vlan)#name tu
S1(config-vlan)#exit
  • kita konfigurasi mode trunk di switch(S2) terlebih dahulu, caranya liat tulisan di bawah ini
S2(config)#interface fa0/1
S2(config-if)#switchport mode trunk
S2(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed tate to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
S2(config-if)#switchport mode trunk
S2(config-if)#switchport trunk allowed vlan 10,20,30
S2(config-if)#exit
  • lalu kita konfigurasi mode trunk di switch(S3) , caranya liat tulisan di bawah ini
S2(config)#interface fa0/2
S3(config-if)#switchport mode trunk
S3(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to up
S3(config-if)#switchport mode trunk
S3(config-if)#switchport trunk allowed vlan 10,20,30
S3(config-if)#exit
  • sekarang kita konfigurasi mode trunk di switch pusat (S1)
S1(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
S1(config)#interface fa0/1
S1(config-if)#switchport mode trunk
S1(config-if)#switchport trunk allowed vlan 10,20,30
S1(config-if)#exit
S1(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to up
S1(config)#interface fa0/2
S1(config-if)#switchport mode trunk
S1(config-if)#switchport trunk allowed vlan 10,20,30
S1(config-if)#exit
  • setelah itu kita cek apakah sudah benar atau belum, dengan cara ketik”do show interface trunk”
S1(config)#do show interface trunk
Port Mode Encapsulation Status Native vlan
Fa0/1 on 802.1q trunking 1
Fa0/2 on 802.1q trunking 1
Port Vlans allowed on trunk
Fa0/1 10,20,30
Fa0/2 10,20,30
Port Vlans allowed and active in management domain
Fa0/1 10,20,30
Fa0/2 10,20,30
Port Vlans in spanning tree forwarding state and not pruned
Fa0/1 10,20,30
Fa0/2 10,20,30
  • jika sudah merasa benar maka konfigurasi trunk sudah beres
  • sekarang kita cek dengan cara ngeping caranya klik gambar pc>desktop>command prompt
ct2
  • selesai……….
