These commands are used to control system logs, passwords, user name, browser configuration options, and display or configure a variety of other system information.
After initially logging onto the system, you should set Privileged Exec password. Remember to record it in a safe place. Use this command to control access to the Privileged Exec level from the Normal Exec level. Use the no form to remove the password.
Syntax
enable password [level level] {0 | 7} password
no enable password [level level]
- level level - Level 15 for Privileged Exec.
- {0 | 7} - 0 means plain password, 7 means encrypted password.
- password - password for this privilege level.
(Maximum length: 8 characters, and is case sensitive)

- flash - Event history stored in flash memory (i.e., permanent memory).
- ram - Event history stored in temporary RAM (i.e., memory flushed on power reset).
- level - One of the level arguments listed in Table 1. Messages sent include the selected level up through level 0.
Level Argument Level Description Syslog Definition emergencies 0 System unusable LOG_EMERG alerts 1 Immediate action needed LOG_ALERT critical 2 Critical conditions LOG_CRIT errors 3 Error conditions LOG_ERR warnings 4 Warning conditions LOG_WARNING notifications 5 Normal but significant condition LOG_NOTICE informational 6 Informational messages only LOG_INFO debugging 7 Debugging messages LOG_DEBUG
