KONFIGURASI VLAN, ROUTING STATIC, DHCP DAN NAT PADA LAYER 3 SWITCH CISCO 3560
Layer 3 switch atau Multilayer Switch adalah switch yang bekerja pada layer 2 dan juga bekerja pada layer 3 yang mempunyai fungsi routing, kemampuan routing pada layer 3 switch antara lain routing antar VLAN berdasarkan encapsulation dot 1Q maupun routing protocol static dan routing protocol dinamis lain seperti Border Gateway Protocol (BGP), Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), dan Routing Information Protocol (RIP). Pada contoh ini akan diperlihatkan langkah melakukan konfigurasi VLAN pada Catalyst 3560 serta routing antar VLAN, Routing Static, DHCP dan juga NAT.
Skenario
| VLAN ID | Nama VLAN | Alamat Subnet |
| 2 | Guest | 192.168.0.0/24 |
| 3 | Student | 192.168.1.0/24 |
| 4 | Lecture | 192.168.2.0/24 |
| Interface | IP address |
| Interface vlan 2 | 192.168.0.1/24 |
| Interface vlan 3 | 192.168.1.1/24 |
| Interface vlan 4 | 192.168.2.1/24 |
| Interface gigabitEthernet 0/1 | 222.124.194.2/27 |

Masuk ke Global Configuration Mode dan lakukan Grouping Port.
Switch#configure terminal
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 2
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/2

Switch(config-if)#switchport access vlan 2
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/3
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 3
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/4
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 3
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/5
Switch(config-if)#switchport mode access

Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/6
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 4
Switch(config-if)#
Buat Interface VLAN yang berfungsi sebagai gateway tiap-tiap VLAN, Nomor Interface VLAN yang dibuat harus sama VLAN ID yang akan dilewatkan, misalnya interface VLAN 2 itu berfungsi sebagai gateway untuk VLAN 2, begitu juga dengan VLAN yang lain.
Switch(config)#interface vlan 2
Switch(config-if)#ip address 192.168.0.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config)#interface vlan 3
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Switch(config)#interface vlan 4
Switch(config-if)#ip address 192.168.2.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#
Untuk memudahan pemberian IP address pada host tiap-tiap VLAN ada baiknya kita membuat DHCP server, dan pada contoh ini kita akan menggunakan IP 222.124.194.11 sebagai DNS server
Switch(config)#ip dhcp pool vlan2
Switch(dhcp-config)#default-router 192.168.0.1
Switch(dhcp-config)#dns-server 222.124.194.11
Switch(dhcp-config)#network 192.168.0.0 255.255.255.0
Switch(dhcp-config)#exit
Switch(config)#ip dhcp pool vlan3
Switch(dhcp-config)#default-router 192.168.1.1
Switch(dhcp-config)#dns-server 222.124.194.11
Switch(dhcp-config)#network 192.168.1.0 255.255.255.0
Switch(dhcp-config)#exit
Switch(config)#ip dhcp pool vlan4
Switch(dhcp-config)#default-router 192.168.2.1
Switch(dhcp-config)#dns-server 222.124.194.11
Switch(dhcp-config)#network 192.168.2.0 255.255.255.0
Switch(dhcp-config)#exit
Switch(config)#
Berikan IP address pada Interface gigabitEthernet 0/1 (anda bisa mengguakan interface lain jika tidak menggunakan interface ini), perhatikan perintah no switchport , perintah ini digunakan agar interface tersebut itu bisa diberi IP address seperti halnya pada router atau interface layer 3, tanpa perintah ini maka interface pada switch hanya sebagai interface layer 2.
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if)#no switchport
Switch(config-if)#ip address 222.124.194.2 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
Buat default routing yang berfungsi sebagai “the last resort” terhadap tujuan packet dalam menuju alamat yang tidak terdapat pada routing tabel, sehingga packet tidak di-dischard atau dibuang dari network.
Switch(config)#ip route 0.0.0.0 0.0.0.0 222.124.194.1
Buat NAT sehingga IP private yang berada pada VLAN bisa ditranlasi menuju IP Public, masuk ke interface gigabitEthernet 0/1 dan setting sebgai NAT Outside, kemudian masuk ke tiap-tiap Interface VLAN yang sudah kita buat dan set sebagai NAT Inside.
Switch(config)#interface gigabitEthernet 0/1
Switch(config-if)#ip nat outside
Switch(config-if)#exit
Switch(config)#interface vlan 2
Switch(config-if)#ip nat inside
Switch(config-if)#exit
Switch(config)#interface vlan 3
Switch(config-if)#ip nat inside
Switch(config-if)#exit
Switch(config)#interface vlan 4
Switch(config-if)#ip nat inside
Switch(config-if)#exit
Switch(config)#
Kemudian buat aturan NAT dan jangan lupa untuk mengatur access-list agar mengizinkan packet untuk lewat, perhatikan juga nomor aturan NAT dan access-list keduanya harus mempunya nomor yang sama, jadi kalau aturan NAT-nya menggunakan nomor 1 maka pada access-list juga harus menggunakan nomor 1.
Switch(config)#ip nat inside source list 1 interface gigabitEthernet 0/1 overload
Switch(config)#access-list 1 permit any
Switch(config)#
Kembali ke Privilege Mode dan simpan hasil konfigurasian
Switch(config)#exit
Switch#copy running-config startup-config

Prinsip Redistribute Routing Protocol
Redistribute adalah cara untuk meredistribusikan kembali routing tabel yang dibentuk oleh suatu routing protocol untuk diteruskan ke routing protocol lain. Dengan redistribute kita bisa membentuk routing tabel yang lengkap dari suatu topologi walaupun menggunakan routing protocol yang berbeda. Pada prinsipnya router yang menjadi penghubung antara network dengan routing protocol yang berbeda akan menggunakan routing protocol sesuai dengan routing protocol yang dipergunakan oleh kedua network tersebut, misal interface F0/0 pada router tersebut berhubungan dengan network yang menggunakan RIP maka router tersebut harus menggunakan RIP dan pada F0/1 menggunakan OSPF maka router tersebut juga harus menggunakan OSPF sesuai dengan network tempat interface tersebut terhubung. Untuk membuat agar routing tabel yang dibentuk oleh RIP bisa diteruskan menuju ke OSPF maka dipergunakan redistribute RIP, dan sebaliknya agar routing tabel yang terbentuk pada OSPF bisa diteruskan menuju RIP maka dipergunakanlah redistribute OSPF.
Contoh dibawah ini adalah redistribute RIP dan OSPF
InterVLAN Routing dengan Vyatta
VLAN dibuat dengan encapsulation dot 1Q berdasarkan IEEE 802.1Q, yaitu terjadi peristiwa tagging oleh switch pada header frame ethernet, berupa VLAN ID, dan dengan tag yang terdapat pada header frame inilah maka switch akan melihat port mana saja yang mempunyai VLAN ID yang sama dengan frame tersebut, frame hanya akan diteruskan menuju port yang di set dengan VLAN ID yang sama dan tidak akan diteruskan menuju port dengan VLAN ID yang berbeda, dengan metode inilah maka terjadilah segmentasi LAN berdasarkan port pada switch, sehingga broadcast yang dihasilkan oleh salah satu host tidak akan diteruskan menuju port dengan VLAN ID yang berbeda atau hanya akan diteruskan ke port dengan VLAN ID yang sama, sehingga terjadi efisiensi pemakaian bandwidth. Kondisi inilah yang membuat VLAN seolah-olah mempunyai banyak LAN dalam pengertian logical tetapi sebenarnya berada dalam satu LAN dalam pengertian physical.
LAN-LAN yang berbeda pada VLAN ini harus mempunyai alamat network yang berbeda, sesuai dengan prinsip dasar di network, maka jika ada dua atau lebih alamat network yang berbeda ingin berkomunikasi maka harus melakukan peristiwa routing. Pada peralatan Cisco, routing antar VLAN bisa dilakukan oeh switch itu sendiri asalkan switch tersebut mempunyai fasilitas routing yaitu Layer 3 Switch, jadi ada switch yang hanya mendukung layer 2 dan ada switch yang mendukung layer 3, tentu dari sisi praktis layer 3 switch lebih praktis, dalam artian kita bisa membuat VLAN sekaligus melakukan routing sehingga antar VLAN yang berbeda tadi bisa berkomunikasi, tetapi dari sisi cost, peralatan switch layer 3 mempunyai harga yang lebih mahal dari switch layer 2.
Sebaliknya jika kita menggunakan switch layer 2 dalam membuat VLAN, kita untuk membuat antar VLAN yang berbeda tadi berkomunikasi atau dengan kata lain melakukan routing antar VLAN maka kita harus menggunakan peralatan tambahan berupa router, tentu dari sisi cost, itu berarti harus ada investasi tambahan peralatan yaitu router. Dari situlah kita berpikir bagaimana membuat jaringan yang handal, efisiensi terhadap cost, tentu sekilas kita melihat seolah ada sesuatu yang berlawanan, (“man uji wong pelembang ado rego ado barang”).
Sebenarnya dua hal itu bukanlah dua hal yang bertentangan asal kita mengerti prinsip keilmuan secara fundamental (back to fundamental back to philosophy), mengerti sebenarnya apa yang terjadi, sehingga mengerti apa yang harus kita lakukan. Ada banyak software opensource yang mendukung encapsulation dot 1 q, antara lain adalah Vyatta (http://vyatta.org - thanks to Vyatta), Vyatta bisa di download secara gratis dan tidak membutuhkan hardware dengan klasifikasi tinggi, dari pengalaman yang sudah dilakukan Vyatta bisa dijalankan pada Pentium III RAM 128 MB dengan harga second dibawah 1 juta rupiah, dan mempunyai kinerja cukup baik (man dipikir-pikir sebenernyo katek yang murah, sebab ilmunyo yang mahal, ilmunyo ini yang betahun-tahun nyarinyo, kopi begelas-gelas nak Cappucino pulok, rokok bebungkus-bungkus, DjiSamSoe pulok, singgonyo dak teritung lagi nilai investasi). Pada studi kasus ini dipergunakan Catalyst 2960-24TT untuk membuat VLAN dan Vyatta versi 5.0.2 untuk Inter VLAN Routing. Untuk lebih jelas mari kita lihat topologi dibawah ini.
Topologi
Pada Studi kasus ini kita akan membuat 5 VLAN
- VLAN 2 labnetwork
- VLAN 3 labrobotika
- VLAN 4 labelektronika
- VLAN 100 webserver
- VLAN 101 databaseserver
VLAN 1 tidak dibuat karena sudah ada secara default dan nanti akan digunakan sebagai VLAN Manajemen
Untuk skema pengalamatan
- 192.168.1.0/24 untuk VLAN Manajemen
- 192.168.2.0/24 untuk VLAN labnetwork
- 192.168.3.0/24 untuk VLAN labrobotika
- 192.168.100.0/24 untuk VLAN webserver
- 192.168.101.0/24 untuk VLAN databaseserver

CONFIGURATION REGISTER
Cisco mempunyai software register 16 bit yang ditulis pada nonvolatile memory. Configuration register diatur secara default untuk me-load Cisco IOS dari flash dan me-load startup-config dari NVRAM
Kita bisa mengubah configuration register untuk keperluan:
- Memaksa system untuk masuk bootstrap monitor
- Memilih sebuah boot source dan default boot filename
- Enable atau men-disable fungsi break
- Mengontrol alamat broadcast
- Mengatur baud rate terminal console
- Me-load software operating dari ROM
- Booting dari TFTP server
Konfigurasi default pada Cisco router adalah 0×2102
Nomor bit pada configuration register
|
16 bit |
||||||||||||||||
| Configuration register | 2 | 1 | 0 | 2 | ||||||||||||
| Bit Number | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| Binary | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 |
Prefix 0x pada alamat configuration register (0×2102) untuk menunjukkan bilangan yang digunakan adalah hexadecimal
Maksud dari Nomor Bit
| Bit No. | Hexadecimal | Deskripsi |
| 0-3 | 0×0000-0×000F | Boot field lihat tabel bootfield |
| 6 | 0×0040 | Abaikan isi NVRAM |
| 7 | 0×0080 | OEM bit enabled |
| 8 | 0×0100 | Break disabled |
| 10 | 0×0400 | IP Broadcast with all zero |
| 11-12 | 0×0800-0×1000 | Kecepatan line console |
| 13 | 0×2000 | Boot default ROM software if network boot fails |
| 14 | 0×4000 | IP broadcast do not have net number |
| 15 | 0×8000 | Enable diagnostic messages and ignore NVRAM contents |
Bit ke 6 digunakan untuk mengabaikan isi dari NVRAM
Boot field
| Boot field | Meaning |
| 00 | ROM Monitor Mode |
| 01 | Boot image from ROM |
| 02-F | Specifies a default netboot filename |
Untuk boot ke mode ROM Monitor atur configuration register ke 0×2100, kemudian reboot router. Pada router akan muncul rommon>
Untuk booting ke mini-IOS images pada ROM (dikenal sebagai RXBOOT), atur configuration register ke 0×2101. Maka akan tampil router(boot)> Jika ini jenis router lama, atau akan muncul rommon 1> jika router berbasiskan RISC terbaru dengan sebuah “smart ROM” pengganti dari mini IOS.
Nilai dari 0×2102 sampai 0×210F untuk memberi tahu pada router untuk menggunakan perintah boot yang spesifik di NVRAM. Semua nilai dalam bentuk hexadecimal, skemanya adalah 0-9 dan A-F. (A=10, B=11, C=12, D=13, E=14, dan F=15). Sehingga kita mengatur configuration register sampai 210(15), atau 1111 dalam bentuk binary.
MENGUBAH CONFIGURATION REGISTER
Sebelum mengubah configuration register, maka perlu mengetahui nilai configuration register yang sudah ada. Pada router ketikkan perintah:

PASSWORD RECOVERY
Bit ke 6 pada configuration register merupakan bit yang digunakan untuk memberi tahu router apakah harus menggunakan isi dari NVRAM, atau malah sebaliknya untuk mengabaikan isi dari NVRAM.
Nilai default dari configuration register adalah 0×2102, dimana bit ke tersebut dinyatakan off, jika nilai ini off maka router akan mencari dan me-loading konfigurasi yang disimpan pada NVRAM (startup-config). Untuk melakukan recovery password, kita perlu memberi nilai pada bit ke 6 tersebut, sehingga router akan mengabaikan startup-config yang terdapat pada NVRAM, sedangkan konfigurasi mengenai password tersendiri disimpan pada startup-config tersebut, jika startup-config diabaikan maka router tidak akan membaca password yang sudah ada.
Untuk melakukan recovery password pada router, hubungkan router pada program hyperterminal. Setelah itu matikanlah router, kemudian pada keyboard computer tekan Control+break, dan nyalakan lagi router. Router akan masuk ke ROM monitor, pada ROM monitor ketik perintah confreg 0×2142
rommon 1 > confreg 0×2142
rommon 2 > reset
Setelah direset maka router akan masuk ke configuration dialog, ketik no
