Parser View

With CLI view, we can restrict which access each network administrator have based on role. Superviews allow a network administrator to easily assign all users within configured CLI views to a superview instead of having to assign multiple CLI views to a group of users. 


Here is the basic configuration of the Parser View.


R2 <----> R3    
192.168.1.1   <---->  192.168.1.2


Task: 

• Allowing telnet access with the username OPERATOR and password CISCO to be able to configure the HTTP feature in the router only.
• Configure Username ADMIN and password CISCO to have access to every feature in the router.

Change parser view configuration

To be able to change the configuration of the parser view, you need to enter the view root. In this example, to enter the view root, we have to telnet with login as ADMIN and "enable view".

R2#telnet 192.168.1.2

Trying 192.168.1.2 ... Open

User Access Verification

Username: ADMIN

Password:

R3#en view

Password:

R3#

On R3, you will have the syslog message:

*Mar  3 22:24:04.582: %PARSER-6-VIEW_SWITCH: successfully set to view 'root'.

Now, you can change the configuration of the parser view.

R3#

R3#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

R3(config)#parser view HTTP ?
