INTER VLAN - Switch Layer 3

Inter Vlan - Switch layer 3


Untuk menghubungkan antar Vlan dibutuhkan suatu perangkat Layer 3 baik itu router maupun switch layer 3. Jika sebelumnya menggunakan router on stik maka sekarang kita akan menggunakan switch layer 3 (L3). Inilah keunggulan perangkat Cisco jika di switch produk lain bekerja hanya pada layer 2, untuk switch Cisco dapat bekerja pada layer 3 dan menjelankan routing , akan tetapi untuk routingnya yang lebih luas dianjurkan menggunakan router.



Konfigurasi switch layer 3

Switch(config-if)#vlan 10
Switch(config-vlan)#name guru
Switch(config-vlan)#vlan 20
Switch(config-vlan)#name siswa
Switch(config-vlan)#int
Switch(config-vlan)#int fa0/1
Switch(config-if)#sw
Switch(config-if)#switchport acu
Switch(config-if)#switchport access vlan 10
Switch(config-if)#swi
Switch(config-if)#switchport Moe
Switch(config-if)#switchport mode acu
Switch(config-if)#switchport mode access
Switch(config-if)#int fa0/2
Switch(config-if)#switchport access vlan 10
Switch(config-if)#switchport mode access
Switch(config-if)#int fa0/3
Switch(config-if)#switchport access vlan 20
Switch(config-if)#switchport mode access
Switch(config-if)#int fa0/4
Switch(config-if)#switchport access vlan 20
Switch(config-if)#switchport mode access

Buat IP address pada interface switch  fa0/1-fa0/4

 Masuk interface Vlan 

Switch(config-if)#int vlan 10
Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan10, changed state to uap
Switch(config-if)#ip address 10.10.10.1 255.255.255.0
Switch(config-if)#int vlan 20
Switch(config-if)#
%LINK-5-CHANGED: Interface Vlan20, changed state to uap
Switch(config-if)#ip address 20.20.20.1 255.255.255.0

Ketikkan ip routing untuk merouting 

Switch(config-if)#ip routing

SSH (SECURE SHELL)

Diposting oleh di - 0 komentar

Melanjutkan teknologi sebelumnya karena jalur telnet menggunakan Lear next yang berarti jalur yang lewat masih bisa dilihat (tidak sama), maka untuk mengamankan jalur remot ini bisa menggunakan SSH (Secure shell)
Yang diperhatikan untuk membuat SSH adalah :
  • Hostname tidak boleh default
  • Harus ada domain Dame
  • Authenticationnya menggunkana username dan password
  • Deskripsikan dijalur telnet bahwa Akan menggunkana SSh
5    Generate Crypto Key.

VLAN TRUNK

            TRUNK berfungsi untuk melewatkan traffic VLAN dari switch yang berbeda, antara switch 1 ke switch ke 2 yang terhubung, PC0,PC1,PC2,PC3 ini masuk VLAN 100. PC8,PC5,PC6,PC7 ini masuk VLAN 200.

Virtual LAN (VLAN)

Diposting oleh di - 0 komentar

            Virtual LAN (VLAN) membagi satu broadcast domain menjadi beberapa broadcast domain, sehingga dalam satu switch bisa saja terdiri dari beberapa network. Host yang berbeda VLAN tidak akan tersabung sehingga security jaringan.

            VLAN adalah fasilitas yang dimiliki oleh siwtch managable, contohnya cisco. Pada switch unmanagable, port-portnya hanya dapat digunakan untuk koneksi ke network yang sama (satu network) sehingga tidak mendukung fasilitas vlan
