The form conventions are described in the table shown under the section "Conventions" on page v of this guide. • Syntax Description - A table where each row describes the optional or required arguments, and their use, that can be issued with the command. • Default - If the command sets a configuration value or administrative state of the switch then any default settings (i.e. without issuing the command) of the configuration is shown here. • Command Mode - The mode in which the command can be issued.

The most important limitation of this account is that there is no way of changing the access right level. • Advanced User- Privilege Level 2. This user account level is very similar to a basic user except that an advanced user can enter privileged EXEC mode. • Power User- Privilege Level 12. This user account level is used to grant system configuration rights for users who need to change or monitor system configuration, except for security related information such as user accounts and SNMP account settings, etc. • Administrator- Privilege Level 15. This administrator user account level can monitor all system information and change any of the system configuration settings expressed in this configuration guide.
