Role-Based CLI Access
The Role-Based CLI Access feature allows the network administrator to define “views,” which are
a set of operational commands and configuration capabilities that provide selective or partial
access to Cisco IOS EXEC and configuration (Config) mode commands. Views restrict user
access to Cisco IOS command-line interface (CLI) and configuration information; that is, a view
can define what commands are accepted and what configuration information is visible. Thus,
network administrators can exercise better control over access to Cisco networking devices.
Configuring a CLI View
Prerequisites

Before you create a view, you must perform the following tasks:
•Enable AAA via the aaa new-model command. (For more information on enabling AAA, see the
chapter
“Configuring Authentication” in the Cisco IOS Security Configuration Guide, Release 12.3.
•Ensure that your system is in root view—not privilege level 15.
SUMMARY STEPS
1. enable view
2. configure terminal
3. parser view view-name

command]
6. exit
7. exit
