Chapter 4 Configuring the PA-POS-2OC3
Configuring the Interfaces
To configure the new interfaces, proceed to the
“Configuring the Interfaces” section on page 4-2
Configuring the Interfaces
After you verify that the new PA-POS-2OC3 is installed correctly (the ENABLED LED goes on), use
the privileged-level
configure
command to configure the new interfaces. Have the following information
available:
•
IP addresses, if you plan to configure the interface for IP routing
•
MTU size
•
Framing mode
•
Transmit clock source
•
Loopback modes (if testing is required)
If you installed a new PA-POS-2OC3 or if you want to change the configuration of an existing interface,
you must enter configuration mode to configure the new interfaces. If you replaced a
PA-POS-2OC3 that
was previously configured, the system recognizes the new interfaces and brings each of them up in their
existing configurations.
For a summary of the configuration options available and instructions for configuring the interfaces on
a PA-POS-2OC3, refer to the appropriate configuration publications listed in the
Documentation” section on page iv
.
You execute configuration commands from the privileged level of the EXEC command interpreter, which
usually requires password access. (See the
“Using the EXEC Command Interpreter” section on page 4-1
for an explanation of the privileged level of the EXEC.) Contact your system administrator, if necessary,
to obtain password access.
On power up, the OC-3 interface on a new PA-POS-2OC3 is shut down. To enable the interfaces, you
must enter the
no shutdown
command in configuration mode. (See
Configuration” section on page 4-3
.) When the OC-3 interface is enabled (taken out of shutdown) with
no additional arguments, the default interface configuration file parameters look like those in
.
