Cisco Recovering Password
Lupa password router Cisco ? Sehingga tidak bisa
login telnet atau SSH, atau ingat password telnet dan SSH tapi lupa passwprd enable
Apabila lupa password dan tidak bisa login, maka
solusinya adalah recovery password agar
file konfigurasi tidak hilang. Ikuti langkah-langkahnya sbb:
1. Matika Router terlebih dahulu
2. Lakukan akses console ke router menggunakan putty
3. Nyalakan router kembali dan tekan tombol CTRL + PAUSE BREAK di keyboad laptop/pc sehingga akan menginterupsi router saat loading dan muncul rommom mode, sampe ada tulisan rommon >1
4. Ketikkan command confreg 0x2142
5. Ketik command reset
6. Ketika no saat setup mode router muncul
7. Kemudian load dan masuk ke starup-config kedalam memory RAM
(running-config)
R-1>#enable
R-1#copy
start run
8. Misalkan password enable lupa, Berarti hanya command bagian enable saja
ubah
R-1#configure
teriminal
R-1(config)#enable
secret cisco
Kembalikan configuration-register sesuai dengan defaultnya yaitu 0x2102 yang artinya router akan membaca NVRAM saat boting, lalu simpan.
R-1(config)#config-register
0x2102
Untuk memilih ios yg baru sebagai ios yang akan jalan dirouter, masuk ke global mode dan ketik perintah dibawah ini.
R-1(config)# boot system flash c1841-adventerprisek9-mz.151-4.M1.bin
R-1(config)#do
copy run start
Verfikasi configuration-register, dan seharusnya akan mumcul dengan mengetik
R-1(config)# version
Configuration register is 0x2102 (will be 0x2102 at next reload)”
dan seharusnya akan mumcul Configuration register is 0x2102
Success...!!!
