reference guides include the task IDs required for each command. If you suspect user group assignment is

Information About Implementing Physical and Virtual Terminals
To implement physical and virtual terminals, you need to understand the concepts in this section.
Line Templates
The following line templates are available in the Cisco IOS XR software.
• Default line template—The default line template that applies to a physical and virtual terminal lines.
• Console line template—The line template that applies to the console line.
• User-defined line templates—User-defined line templates that can be applied to a range of virtual terminal
lines.
Line Template Configuration Mode
Changes to line template attributes are made in line template configuration mode. To enter line template
configuration mode, issue the line command from Global Configuration mode, specifying the template to
be modified. These line templates can be configured with the line command:
• console—console template
• default—default template
• template—user-defined template
After you specify a template with the line command, the router enters line template configuration mode
where you can set the terminal attributes for the specified line. This example shows how to specify the attributes
for the console:
RP/0/RSP0/CPU0:router(config)# line console
RP/0/RSP0/CPU0:router(config-line)#
From line template configuration mode, use the online help feature ( ? ) to view all available options. Some
useful options include:
• absolute-timeout—Specifies a timeout value for line disconnection.
• escape-character—Changes the line escape character.
• exec-timeout—Specifies the EXEC timeout.
• length—Sets the number of lines displayed on the screen.
