Он помоему после пяти раз блокирует телнет-сессию, а пароль там скинуть проще паренной репы, даже конфиг целый останеться...

Step−by−Step Procedure To recover your password, follow the steps below: Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal settings: 9600 baud rate ¨ No parity ¨ 8 data bits ¨ 1 stop bit ¨ No flow control ¨ For additional information on cabling and connecting a terminal to the console port or the AUX port, refer to the following documents: Cabling Guide for Console and AUX Ports on Cisco Routers ¨ Connecting a Terminal to Catalyst 2948G−L3, 4908G−L3, and 4840G Series Switches ¨ Catalyst 8510CSR, and 8540CSR Switches Console Port Pinouts ¨ 1. If you still have access to the router, type show version and record the setting of the configuration register; it is usually 0x2102 or 0x102. Click here to see the output of a show version command. 2. If you don't have access to the router (because of a lost login or TACACS password), you can safely consider that your configuration register is set to 0x2102. 3. Using the power switch, turn off the router and then turn it back on. 4.
