Protecting Configuration Parameters

The following parameter protection commands prevent display or modification of configuration parameters:

Once protected, a parameter can be unprotected only by removing protection and rebooting the terminal.

You can protect parameters in a remote configuration file or through a TELNET connection.

You can use protection commands to protect certain parameters while allowing users to change others. You can protect individual parameters, entire groups, or all parameters.

All protected parameters are commented; that is, a pound sign (#) is inserted in front of their names. If you try to display a parameter that is protected from display, its value as shown as "<GET-PROTECTED>." If you try to change a parameter that is protected from modification, an error message is displayed.

Using the protect Command

The protect command prevents both display and modification of parameter values. The protect command has three forms:

protect parameter Protects one or more specific parameters from display and modification
protect group Protects one or more groups of parameters
protect all Protects all parameters

For example, the following command protects all parameters in the serial group, ensuring that serial port configuration is not changed: 


protect serial

Using the get-protect Command

The get-protect command prevents display of parameter values. Parameters protected with this command can be modified, but not displayed. The get-protect command has three forms:

get-protect parameter Protects one or more specific parameters from display
get-protect group Protects one or more groups of parameters
get-protect all Protects all parameters

Using the set-protect Command

The set-protect command prevents modification of parameter values. Parameters protected with this command can be displayed, but not modified. The set-protect command has three forms:

set-protect parameter Protects one or more specific parameters from modification
set-protect group Protects one or more groups of parameters
set-protect all Protects all parameters

Removing Parameter Protection

Once a parameter is protected, no one can modify (or display) it without resetting the terminal or editing the configuration file. The method for disabling parameter protection depends on whether the protect command was written to a configuration file:
