2 CISCO IOS Software and CISCO LAN SWITCHES

3 Tujuan Kuliah ini Memperkenalkan CISCO CLI commands Memperkenalkan IOS CISCO proprietary software dan ciri-cirinya, konsep Memperkenalkan CISCO LAN switches ciri dan konsep Memahami konfigurasi router IOS upgrade Perkenalan Switch IOS dan konfigurasi Konfigurasi IOS

4 CLI IOS Software CLI- Command line interface CISCO menggunakan CLI untuk ke terminal user command line interface Metode mengaksesnya –Console port - Serial console cable –Aux port – Modem –Telnet – via connected network – 5 concurrent sessions vty0-4 Setiap akses memiliki password yang terpisah

5

6 Console port -RS232 serial port seperti Com 1 dan 2 pada PC -Memiliki RJ45 konektor tapi menggunakan kabel yang berbeda – rollover cable

7 CLI MODES CLI modes User exec mode (user mode) Perintah yang Non critical dan tidak ada konfigurasi Privileged exec mode (privileged mode)

8

9 Help Commands Help commands - help -Command ? -command parm?

10

11 Command edits Command Edit  Lihat Table 7-4  Turning terminal editing on/off

12 SHOW Commands Show command Memunculkan system variables dan settings

13 Debug Command Debug commands: Monitor proses dan log stats dan pesan (sys log messages) Ketika difungsikan akan berakibat secara drastis pada kinerja router dan kinerja jaringan Matikan dengan perintah : debug all / no debug all

14 Configuration Mode Configuration modes Masuk user mode Kemudian masuk privileged mode Kemudian masuk config mode Some commands use sub commands Melihat proses konfigurasi dengan perintah show running-config

16 Router Memory RAM; biasa disebut DRAM, RAM digunakan router untuk working storage, file konfigurasi yang sedang berjalan disimpan disini. ROM; menyimpan bootable IOS image, ROM berisi code yang digunakan untuk boot router sampai router tahu dimana mendapatkan full IOS image

17 Router Memory Flash memory; jenisnya EEPROM atau PCMCIA card, fungsinya untuk menyimpan secara penuh IOS image dan tempat default dari router untuk boot, tempat ini juga bisa menyimpan file konfigurasi NVRAM; menyimpan stratup config file

18 Router Interfaces Merujuk kepadsa setiap port atau slot Router yang lebih besar menggunakan slot/port i.e. 2/3 slot 2 port 3

19 Start up configuration Start up -Startup configuration file for the IOS -Disebut startup-config -Disimpan di NVRAM Copying: -Copy command Copy dari atau NVRAM (stratup-config), RAM (running-config ) atau TFTP -Fig 7-5 -Fig 7-6 has old style commands

20 Configuration Interactive configuration facility Starts on bootup or by using the command “setup” Walk through example 7-5

21 IOS Upgrade Upgrading the IOS What we have been dealing with is simply a config file? The router has a complete operating system (IOS) in flash memory Flash is like an electronic re-writable disk drive Sometimes the operating system needs to be upgraded (new features)

22 Downloading IOS Downloading the IOS Fig 7-8 Download the file from the Cisco web site Put on a PC with a TFTP server Example 7-6 Use the copy tftp flash command (at router CLI) to download into router

23 Download steps -Preliminary download Information -5 points Page 196

24 IOS Name IOS name (p197) -First part is hardware platform- c2600 -Followed by the feature set- js -File format- 1 (relocatable and not compressed) -Version number: 12.13 -A “Z” at the end means file is zipped c2600-js-1_121-3. bin

25 Show flash  Verify Show flash  Limited IOS in ROM  Limited backup IOS in ROM in case IOS in flash is missing or corrupt  This mode is called rxboot mode  Can TFTP to a TFTP server (on the same subnet only)  ROMMON  Another limited IOS in ROM for debugging and password recovery

26 Boot system commands 1Boot system command oOptions Table 7-6

27 CISCO LAN Switches  Switches  We use 2950 with 24 10/100 Mbps ports  Interface numbering slot/port  Inbuilt ports are slot 0 i.e. 0/1, 0/2  LEDs on front panel – Table 8-2 - POST

28 CISCO LAN Switches  Switch IOS  Older Catalyst switches had different interface  New Cisco switches have the same CLI as the routers  Access methods are the same as the routers  Fig 8-2 Interactive switch configuration
