PASSWORD RECOVERY PROCEDURE ON a 2900 SERIE SWITCH

ZABRANJENO JE OVU TEMU KOPIRATI NA DRUGE FORUME BEZ DOZVOLE ( www.ic.ims.hr )

Pristup isključivo preko Console konekcije

Host1 C:\# ping 192.168.1.2
To regain access to the switch, you need to do password recovery. Start by connecting to do console port with a PC.
When all hardware is ready, turn OFF power to the switch.
Turn the power BACK ON, while holding down the mode button. Release the MODE button when the LED over port 1 goes out.
( Uključite ponovno switch ali držeći tipku MODE pritisnutu. Kada se LED dioda na portu 1 ugasi onda pustite MODE tipku ).

Host1 C:\# NEXT.
Host1 C:\#flash_init ( naredba za početak procedure vraćanja passworda )
Host1 C:\#load_helper ( učitavanje pomoći )
Host1 C:\#dir flash: ( očitavanje sastava direktorija Flash )
Switch#rename flash:config.text flash:config.old ( preimenovanje datoteke config.text u config.old
Switch#boot ( rebootanje switcha )
……………….nakon restarta switcha pojavljuje se puno ############################### i naziv BIN datoteke.
Pred kraj podizanja switcha pojavljuje se pitanje:
Continue with configuration dialog? [yes/no] N ( upišite N za NO )

Switch#rename flash:config.old flash:config.text ( preimenovanje datoteke config.old u config.text

Switch#enable ( ulaz u EXEC mode )

Switch#copy flash:config.text system:running-config ( kopiranje config.text u trenutno pokrenutu konfiguraciju running-config )

Destination file name [running-config]? running-config ili ENTER ( destinacijski file )

Switch#configure terminal ( ulaz u global configuration mode )

Switch(config)#no enable secret ( brisanje lozinke koja je bila upisana kao SECRET )

Switch(config)#enable password cisco ( postavljanje nove lozinke cisco)
Switch(config)#enable secret class ( postavljanje nove lozinke console line)


Switch(config)#line console 0 ( ulaz u config mode za console konektiranje PC-to_switch )
Switch(config-line)#password cisco ( postavljanje passworda cisco )
Switch(config-line)#exit
Switch(config)#line vty 0 15 ( ulaz u config mode za TELNET konektiranje )
Switch(config-line)#password cisco ( postavljanje passworda cisco )
Switch(config-line)#exit
Switch(config)#exit
Switch#copy running-config startup-config ( spremanje trenutno pokrenute konfiguracije u NVRAM )
