Configuring an Unchannelized T3 Link
If you installed a new PA-MC-T3-EC or if you want to change the configuration of an existing
PA-MC-T3-EC link, you must enter the privileged level of the EXEC command interpreter and then use
the
configure
command. If you replace a PA-MC-T3-EC that was previously configured, the system
recognizes the new PA-MC-T3-EC link and brings it up in its existing configuration.
After you verify that the new PA-MC-T3-EC is installed correctly (the ENABLED LED goes on), use
the privileged-level
configure
command to configure the new interface. Be prepared with the
information you need, such as the following:
•
Protocols you plan to route on each new interface
•
IP addresses, if you plan to configure the interfaces for IP routing
The
configure
command requires privileged-level access to the EXEC command interpreter, which
usually requires a password. Contact your system administrator if necessary to obtain EXEC-level
access.
