Cara Recovery Password Catalyst 2950

with one comment

Coba-coba cisco catalyst 2950 eh malah gak tahu passwordnya apa, dah ditanyain kemana-mana pada gak tahu juga passwordnya apa, akhirnya ya udah aku disuruh password recovery aja ni switch. Berikut caranya :

Matikan catalyst dengan cabut kabel powernya dan sambungkan kembali, jika sudah menyala segera tekan tombol mode di sebelah kiri bawah hingga lampu LED syst menyala kekuning-kuningan.

Langsung saja kita ke terminal console kita disini saya menggunakan aplikasi minicom karena saya menggunakan OS Linux. Jika tampilan sudah seperti ini segera ikuti step-step berikutnya :

Welcome to minicom 2.3
OPTIONS: I18n
Compiled on Oct 24 2008, 06:37:44.
Port /dev/ttyUSB2

Press CTRL-A Z for help on special keys

switch: AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
Unknown cmd: AT
switch:

Pertama ketikkan flash_init

switch: flash_init
Initializing Flash…
flashfs[0]: 16 files, 2 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 7741440
flashfs[0]: Bytes used: 4166144
flashfs[0]: Bytes available: 3575296
flashfs[0]: flashfs fsck took 7 seconds.
…done initializing flash.
Boot Sector Filesystem (bs:) installed, fsid: 3
Parameter Block Filesystem (pb:) installed, fsid: 4

Lalu jika sudah ketikkan load_helper

switch: load_helper

Lalu lihat dimana direktori atau lokasi file config.text berada dengan perintah dir flash: pastikan diakhiri dengan karakter semicolon “:”

switch: dir flash:
Directory of flash:/
2    -rwx  2490607   <date>               c2950-i6q4l2-mz.121-9.EA1.bin
3    -rwx  269       <date>               env_vars
4    -rwx  1378      <date>               config.text
5    -rwx  108       <date>               info
6    -rwx  736       <date>               vlan.dat
7    drwx  640       <date>               html
18   -rwx  108       <date>               info.ver
3575296 bytes available (4166144 bytes used)

Rename file config.text

switch: rename flash:config.text flash:config.text.lama

Lalu kita boot saja jika sudah di rename file config nya

switch: boot
Loading “flash:c2950-i6q4l2-mz.121-9.EA1.bin”…#############################################################################################################
