1 Switch Configuration

2 Console Cable  Console connections can be made between PCs and routers or switches. Certain conditions must be met for the console session from the PC to work:  the speed on both sides of the connection must be the same,  the data bits must be 7 for both or 8 for both,  the parity must be the same,  the stop bits must be 1 or 2 (but they do not have to be the same), and  the flow control can be anything for either side.

3 SWITCH COMMAND LINE INTERFACE (CLI) Switch>? Exec commands: Access-enable membina masukan Senarai Access sementara Clear Fungsi penetapan semula ‘reset’ Connect Buka sambungan terminal Disable Tamatkan arahan Disconnect Putuskan sambungan internet Enable Mulakan arahan **Command-line Interface (CLI) untuk Cisco switch adalah serupa dengan CLI untuk Cisco Router.

4 Mod Arahan Switch ArahanPenerangan Show versionMemberikan versi maklumat untuk perisian (software) dan perkakasan (hardware). Melihat dengan tepat modul dan perisian yang digunakan Show running-configMemaparkan konfigurasi fail semasa switch Show interfaceMemaparkan status pengurusan dan operasi switching port,packet in/out, and kesilapan (errors). Show interface statusMemaparkan mod operasi daripada port Show controllers ethernet-controller Memberikan frame yang dibuang, menunda frames, penjajaran errors, perlanggaran Show postMemberitahu sama ada switch melalui Power-On Self Test (POST)

5  Arahan enable digunakan untuk menukar dari mod Pengguna EXEC kepada mod Privileged EXEC.  Mod Privileged EXEC dikenalpasti daripada prompt, dimana berakhir dengan pound-sign character (#).

6 ADMINISTRATOR SETTING Kita boleh mengubah konfigurasi administrative bagi switch seperti berikut:  Hostname  Banners  Password  Interface description

7 Hostname  A hostname - label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, or Usenet

8 Banner Banner – satu cara untuk memaparkan maklumat switch. Banners terbahagi kepada beberapa jenis: i.exec process creation ii.Incoming terminal line iii.Login iv.Message of the day

9 Password  Password – untuk tujuan keselamatan. Terdiri daripada 5 kategori. Console Auxiliary Telnet (VTY) Enable password Enable secret

10 Interface Description  Arahan untuk kenalpasti circuit numbers. Contoh: Atlanta(config)#int e0 Atlanta(config-if)#description Sales Lan

11  Contoh paparan dalam arahan show running- config dan show interface command Atlanta#sh run [cut] interface Ethernet0 description Sales Lan ip address no ip directed-broadcast

12  Atlanta#sh int e0 Ethernet0 is up, line protocol is up Hardware is Lance, address is be8.25db (bia0010.7be8.25db) Description: Sales Lan [output cut]

13 PENETAPAN SEMULA KONFIGURASI SWITCH DAN RELOAD Catalyst 2950 Switch#delete flash : vlan.dat Delete filename (vlan.dat)? Delete flash : vlan.dat? (confirm) Switch#erase startup-config Switch #reload Catalyst 1900 Switch#delete nvram

14 Langkah-langkah untuk memastikan konfigurasi baru untuk ganti konfigurasi sedia ada.  Keluarkan informasi VLAN yang sedia ada dengan delete fail pangkalan data (data base) vlan.dat daripada direktori flash  Padamkan fail konfigurasi sokongan (back up) startup-config  Reload switch

15 Frame Relay Technology  Frame Relay adalah Packet-switched Technology  Dikelasifikasikan sebagai non-broadcast multi access (NBMA) network  FR mempunyai technology akar dipanggil X.25.  Lebih komplek daripada lease-line network.  Selalunya akan digambarkan sebagai ‘awan’ di dalam network.
