Chapter 5 Configuring the Channelized Mode
Using the EXEC Command Interpreter
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the
EXEC
(also called enable mode)
.
You must enter the privileged level of the EXEC command interpreter with
the
enable
command before you can use the
configure
command to configure a new interface or change
the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).
At the console terminal, use the following procedure to enter the privileged level:
Step 1
At the user-level EXEC prompt, enter the
enable
command. The EXEC prompts you for a
privileged-level password as follows:
Router>
enable
Password:
Step 2
Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
Router#
Replacing an Existing Port Adapter
Before you remove or replace a port adapter, use the
shutdown
command to disable the port adapter to
prevent anomalies when you remove and reinstall the port adapter. When you shut down an interface, it
is designated
administratively down
in the
show
command displays.
Follow these steps to shut down an interface:
Step 1
Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the
“Using
the EXEC Command Interpreter” section on page 5-7
for instructions.)
Step 2
At the privileged-level prompt, enter configuration mode and specify that the console terminal is the
source of the configuration subcommands, as follows:
Router#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Step 3
Shut down the T3 controller on the PA-MC-T3-EC with the
shutdown
controller command.
This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with
the
no shutdown
controller command.
The example that follows is for a port adapter in slot 1 of a Cisco 7200 VXR router:
Router(config)#
controller T3 1/0
Router(config-controller)#
shutdown
Router(config)#
controller T3 1/1
Router(config-controller)#
shutdown
Note
Both T3 ports of the PA-MC-T3-EC should be shut down before removing the port adapter.
