Protocol

Protocol enable network communication from one host through the network to another host. A protocol is a formal description of a set of rules and conventions that govern a particular aspect of how devices on a network communicate. Determine the format, timing, sequencing, and error control in data communication. Without protocols, the computer cannot make or rebuild the stream of incoming bits from another computer into the original format

Protocol

How the physical network is built How computers connect to the network How the data is formatted for transmission How that data is sent How to deal with errors

OSI Layers

Hub, Repeater

OSI Layers

•Provides connectivity and path selection between two host

•Provides Logical address

•No error correction, best effort delivery.

•Device : NIC, Bridges, Switch

Peer-to-Peer Communication

Protocol TCP/IP

DoD Model Standard for MilitaryOpen standard First Protocol used in Internet4 layer Encapsulation Data Packet

18

TCP is a connection-oriented protocolConnections ReliableCirinya :semua paket mendapat tandaterima, paket error maka akan dikirimulang, setelah sampai paket akan diurutkembali

TCP/IP Model

19

Applications Layer

Telnet, FTP, SMTP, TFTP, DNS, SMTP

Transport Layer (host to host)

Protocolnya TCP (Transmision Control Protocol) dan UDP (user datagram protocol)TCP berfungsi untuk mengubah satu blok data yang besar menjadi segmen-segmen yang dinomori dan disusun secara berurutanUDP jenis protocol connectionless oriented, dimana penerima tidak menerima tanda terima, namun unggul dalam penggunaan bandwidth

20

Internet Layer

Protocolnya : IP (internet protocol)ARP (address resolution protocol)DHCP (dynamic host control protocol)ICMP (internet control configuration protocol)RARP (Reverse address resolution protocol)BOOTP (Boostrap Protocol)

Network Access layer

Protocolnya : ethernet, Token ring danFDDI

Connecting Console Interfaces

1. Configure terminal emulation software on the PC for the following:

The appropriate com port 9600 baud 8 data bits 1 stop bit No parity No flow control

2. Connect a rollover cable to the router console port (RJ-45 connector).

3. Connect the other end of the rollover cable to the RJ-45 to DB-9 adapter

4. Attach the female DB-9 adapter to a PC.

Router User Interface Modes

46

User EXEC mode

User EXEC mode : mode ini level paling bawah, logon pertama ke router, digunakan untuk memeriksa statistik daninformasi dasar router.Perintahnya : ping, traceroute, telnet,en, exit,logout, showRouter >

Privilege EXEC mode

Lapisan lebih tinggi user EXEC mode, mendapatkan informasi lebih detail, melakukan pengujian, debugging, danmanipulasi filePeritah : clock, config, copy, debug, disable,disconnect, exit, erase, ping reloadRouter>Router>enrouter#

47

Global Config Mode

Lapisan paling tinggi, dpt melakukankonfig secara global, seting acl ataufirewall, banner, FR, nama hostPerintah : access-list,banner,cdp,config-register,en, exit,exec-timeout, framerelay, hostname,int,loginRouter#Router#config tRouter(config)#
