DuraMAR 2150 – User’s Manual
Configuration Mode
The Configuration Mode is used to configure the system. This mode provides two sub-modes of operation:
Global or Specific, depending on what part of the system the user is configuring. Specific mode allows
access to the configuration area of one of the system components, hardware or software, while Global mode
allows access to global configuration parameters affecting the whole system.
To enter the Configuration Mode from User Mode issue the command:
configure. When entering
Configuration Mode you will find yourself in Global configuration mode.
The system prompt changes to indicate that now you are in Global configuration mode as shown below:
HSDPA-rt(config)#
Commands entered in Configuration Mode update the running configuration immediately, as soon as the
command is entered. However, these changes are not saved in the start-up configuration file until you issue
the
copy running User mode command to save the configuration.
Entering a string identifying a specific system component while in Configuration Mode makes the user enter
the Specific configuration mode. Commands available in this mode are specific for the component you are
configuring.
As an example, to configure the Ethernet interface (
eth0), you will issue the command interface eth0.
Entering this command moves you to the specific configuration mode of the selected component and the
prompt changes accordingly as shown in the following example below:
HSDPA-rt(config)# interface eth0
HSDPA-rt(config-if-eth0)#
While in Specific configuration modes such as in the example above, the commands available are only
related to the specific component as shown below:
HSDPA-rt(config-if-eth0)# ?
description Interface description
IP IP Protocol config commands
enable Enable the selected interface
mobile Enable mobile subsystem on this interface
mtu Change the mtu size for this interface
nat Enable NAT services on this interface
exit Exit from interface configuration mode
To exit from Specific configuration mode thus returning to Global configuration mode use the exit
command. To end the configuration session issue the
exit command from Global configuration mode.
Using the no-form of commands
Almost every configuration command has a no-form that is used to reset or disable the specific configuration
parameter/value.
For example the following commands:
HSDPA-rt(config-if-eth0)# enable
HSDPA-rt(config-if-eth0)# no enable
will first enable (or activate) and then disable (or deactivate) the Ethernet interface.
