Cisco Systems PA-POS-1OC3 Manual De Usuario

To configure the new interfaces, proceed to the 

.

After you verify that the new PA-POS-1OC3 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-1OC3 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-1OC3 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-1OC3, refer to the appropriate configuration publications listed in the 

. 

You execute configuration commands from the privileged level of the EXEC command interpreter, which 
usually requires password access. (See the 

 

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-1OC3 is shut down. To enable the interfaces, you 
must enter the no shutdown command in configuration mode. (See 

.) 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 

1.

These default parameters apply to the PA-POS-1OC3 in all supported platforms.
