Recovering the Password

Recovering the Password for the Appliance

This section describes the two ways to recover the password for appliances. It contains the following topics:

•Using the GRUB Menu, page E-8

•Using ROMMON, page E-8

Using the GRUB Menu

Note You must have a terminal server or direct serial connection to the appliance to use the GRUB menu to recover the password.

For the IPS 4270-20, IPS 4345, IPS 4360, IPS 4510, and IPS 4520 appliances, the password recovery is found in the GRUB menu, which appears during bootup. When the GRUB menu appears, press any key to pause the boot process. To recover the password on appliances, follow these steps:

Step 1 Reboot the appliance to see the GRUB menu.

GNU GRUB version 0.94 (632K lower / 523264K upper memory)

Step 2 Press any key to pause the boot process.

Step 3 Choose 2: Cisco IPS Clear Password (cisco). The password is reset to cisco. Log in to the CLI with username cisco and password cisco. You can then change the password.

Using ROMMON

For the IPS 4345, IPS 4360, IPS 4510, and IPS 4520, you can use the ROMMON to recover the password. To access the ROMMON CLI, reboot the sensor from a terminal server or direct connection and interrupt the boot process. To recover the password using the ROMMON CLI, follow these steps:

Step 1 Reboot the appliance.

Step 2 To interrupt the boot process, press ESC or Control-R(direct connection). The boot code either pauses for 10 the following:
