Secure Sensitive Data Configuration Files 19 • Configuration commands with encrypted sensitive data, that are encrypted with the key generated from the local passphrase, are configured into the Running Configuration. Otherwise, the configuration command is in error, and is not incorporated into the Running Configuration file. Backup and Mirror Configuration File A device periodically generates its Mirror Configuration file from the Startup Configuration file if auto mirror configuration service is enabled. A device always generates a Mirror Configuration file with encrypted sensitive data. Therefore, the File SSD Indicator in a Mirror Configuration file always indicates that the file contains encrypted sensitive data. By default, auto mirror configuration service is enabled. To configure auto mirror configuration to be enabled or disabled, click Administration > File Management > Configuration File Properties. A user can display, copy, and upload the complete mirror and backup configuration files, subject to SSD read permission, the current read mode in the session, and the file SSD indicator in the source file as follows: • If there is no file SSD indicator in a mirror or backup configuration file, all users are allowed to access the file. • A user with Both read permission can access all mirror and backup configuration files. However, if the current read mode of the session is different than the file SSD indicator, the user is presented with a prompt indicating that this action is not allowed. • A user with Plaintext Only permission can access mirror and backup configuration files if their file SSD Indicator shows Exclude or Plaintext Only sensitive data. • A user with Encrypted Only permission can access mirror and backup configuration files with their file SSD Indicator showing Exclude or Encrypted sensitive data. • A user with Exclude permission cannot access mirror and backup configuration files with their file SSD indicator showing either encrypted or plaintext sensitive data. The user should not manually change the file SSD indicator that conflicts with the sensitive data, if any, in the file. Otherwise, plaintext sensitive data may be unexpectedly exposed.

Secure Sensitive Data

Configuration Files

Cisco Small Business 200 Series Smart Switch Administration Guide

265

•

Configuration commands with encrypted sensitive data, that are encrypted

with the key generated from the local passphrase, are configured into the

Running Configuration. Otherwise, the configuration command is in error,

and is not incorporated into the Running Configuration file.

Backup and Mirror Configuration File

A device periodically generates its Mirror Configuration file from the Startup

Configuration file if auto mirror configuration service is enabled. A device always

generates a Mirror Configuration file with encrypted sensitive data. Therefore, the

File SSD Indicator in a Mirror Configuration file always indicates that the file

contains encrypted sensitive data.

By default, auto mirror configuration service is enabled. To configure auto mirror

configuration to be enabled or disabled, click

Administration > File Management >

Configuration File Properties

A user can display, copy, and upload the complete mirror and backup

configuration files, subject to SSD read permission, the current read mode in the

session, and the file SSD indicator in the source file as follows:

•

If there is no file SSD indicator in a mirror or backup configuration file, all

users are allowed to access the file.

•

A user with Both read permission can access all mirror and backup

configuration files. However, if the current read mode of the session is

different than the file SSD indicator, the user is presented with a prompt

indicating that this action is not allowed.

•

A user with Plaintext Only permission can access mirror and backup

configuration files if their file SSD Indicator shows Exclude or Plaintext Only

sensitive data.

•

A user with Encrypted Only permission can access mirror and backup

configuration files with their file SSD Indicator showing Exclude or

Encrypted sensitive data.

•

A user with Exclude permission cannot access mirror and backup

configuration files with their file SSD indicator showing either encrypted or

plaintext sensitive data.

The user should not manually change the file SSD indicator that conflicts with the

sensitive data, if any, in the file. Otherwise, plaintext sensitive data may be

unexpectedly exposed.
