About Passwords

Modem Support

The auxiliary port of the Cisco ONS 15530 provides modem connection support. The following settings on the modem are required:

•Enable auto answer mode.

•Suppress result codes.

•Ensure auxiliary port terminal characteristics, such as speed, stop bits, and parity, match those of the modem.

You can configure your modem by setting the DIP switches on the modem itself or by setting them through terminal equipment connected to the modem. Refer to the user manual provided with your modem for the correct configuration information.

For further details on configuring ports and modems for management access, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Dial Services Configuration Guide: Terminal Services.

About Passwords

You can configure both an enable password and an enable secret password. For maximum security, the enable password should be different from the enable secret password.

Enable Password

The enable password is a nonencrypted password that controls access to various commands and configuration modes. It contains from 1 to 25 uppercase and lowercase alphanumeric characters. Give the enable password only to users permitted to make configuration changes to the Cisco ONS 15530.

Enable Secret Password

The enable secret password is a secure, encrypted password. On systems running Cisco IOS, you must type in the enable secret password before you can access global configuration mode.You must type in the enable secret password to access boot ROM software.

Caution If you specify an encryption-type and then enter a clear text password, you will not be able to reenter enable mode. You cannot recover a lost password that has been encrypted by any method.

An enable secret password contains from 1 to 25 uppercase and lowercase alphanumeric characters. The first character cannot be a number. Spaces are valid password characters. Leading spaces are ignored; trailing spaces are recognized.

You will configure passwords in the next section, Configuring IP Access on the NME Interface.
