Chapter 4 Configuring the PA-2FE

Configuring the Interfaces

Configuring the Interfaces

After you verify that the new PA-2FE is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

•Protocols you plan to route on each new interface

•IP addresses, if you plan to configure the interfaces for IP routing

•Bridging protocols you plan to use

If you installed a new PA-2FE 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-2FE that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

You can configure each of the interfaces on a PA-2FE at:

•100 Mbps, half duplex, for a maximum aggregate bandwidth of 200 Mbps per pair. Half-duplex operation is the default.

•200 Mbps, full duplex, for a maximum aggregate bandwidth of 400 Mbps per pair.

You can also configure one PA-2FE interface at 100 Mbps, half duplex, and the second PA-2FE interface at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 300 Mbps per pair.

For a summary of the configuration options available and instructions for configuring interfaces on a PA-2FE, refer to the appropriate configuration publications listed in the “Related Documentation” section on page viii.

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the “Using the EXEC Command Interpreter” section on page 4-1for an explanation of the privileged level of the EXEC.)

This section contains the following subsections:

•Performing a Basic Interface Configuration, page 4-7

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured 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 4-1for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration commands, as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

PA-2FE-FX, PA-2FE-TX specifications

Cisco Systems PA-2FE-TX and PA-2FE-FX are high-performance Ethernet interface modules designed to enhance the capabilities of Cisco 2600 and 3600 series routers. They provide businesses with flexible and reliable networking solutions that meet the increasing demand for bandwidth and connectivity.

One of the main features of the PA-2FE-TX module is its ability to support two 10/100 Mbps Fast Ethernet interfaces. This allows organizations to connect multiple devices while improving network performance. The PA-2FE-FX module, on the other hand, is designed for optical fiber connections. It features two Fast Ethernet interfaces that utilize an SC connector for easier cable management in fiber optic environments. This capability facilitates long-distance data transmission, making it suitable for backbone connections or inter-building links.

Both modules incorporate advanced technologies to ensure efficient data handling. They support Cisco's Auto-Negotiation feature, enabling devices to automatically select the optimal speed and duplex settings, thus simplifying deployment and reducing configuration errors. This functionality is vital in environments with varied device capabilities, allowing seamless communication across the network.

The PA-2FE-TX and PA-2FE-FX modules utilize Quality of Service (QoS) capabilities to prioritize traffic, ensuring that critical applications receive the necessary bandwidth. This is particularly beneficial for VoIP services, video conferencing, and other latency-sensitive applications. Additionally, the modules offer support for VLANs, allowing organizations to segment their networks effectively and enhance security by isolating sensitive data traffic.

Another important characteristic of these modules is their hot-swappable nature, enabling users to replace them without powering down the router, thus minimizing downtime. This feature is critical for businesses that require high availability and reliability from their networking equipment.

In summary, the Cisco Systems PA-2FE-TX and PA-2FE-FX interface modules stand out for their versatility, enabling businesses to implement customized networking solutions tailored to specific needs. With support for both copper and fiber connections, advanced QoS features, and seamless integration into existing Cisco routers, these modules reinforce Cisco’s commitment to providing innovative, robust network solutions that cater to the demands of modern enterprise environments.
