Checking the Configuration

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.

Note For complete command descriptions and examples for all of the supported platforms, refer to the documentation resources listed in the “Related Documentation” section on page vi.

Cisco 7200 Series, Cisco 7100 Series, and Cisco uBR7200 Series show Commands

With the show interfaces type slot/port command, use arguments such as the interface type (fastethernet, and so forth) and the port number (slot/port) to display information about a specific interface only. The following example of the show interfaces fastethernet command shows information specific to the Fast Ethernet interface on the first PA-FE in slot 4:

Router# show interfaces fastethernet 4/0

FastEthernet4/0 is administratively down, line protocol is down Hardware is DEC21140, address is 10.0.0.0 (bia 0000)

Note For the Cisco 7206VXR and Cisco 7206 router shelves, the show interfaces command requires a shelf number in the format show interfaces type shelf number/port adapter slot/interface.

Use the show version command to display the configuration of the system hardware (the number of each port adapter type installed), the software version, the names and sources of configuration files, and the boot images. Following is an example of the show version command:

Router# show version

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

Cisco Systems PA-FE-TX and PA-FE-FX are essential components in the realm of network switching and connectivity. These Peripheral Adapter modules are designed for use in Cisco 7000 series routers, catering to the needs of high-performance networking and offering robust features.

The PA-FE-TX module is equipped with fast Ethernet ports that provide high-speed network connectivity through twisted-pair cabling. This module supports 10/100 Mbps data rates, making it ideal for connecting end-user devices to the network while ensuring compatibility with existing infrastructure. Its auto-sensing capability facilitates smooth integration into varying network environments, allowing for seamless communication and data transfer.

On the other hand, the PA-FE-FX module is tailored for fiber optic connections, enabling high-speed data transmission over longer distances. This module supports multimode and single-mode fiber options, catering to diverse connectivity requirements. The PA-FE-FX is essential for organizations that require extended reach and minimal signal degradation, making it suitable for large campuses, data centers, and urban networking.

Both modules leverage Cisco's advanced technologies, including Quality of Service (QoS) capabilities and enhanced security features. These protocols ensure efficient bandwidth management and prioritize critical applications, improving overall network performance. Additionally, they support features such as VLAN (Virtual Local Area Network) tagging, enabling network segmentation and improved traffic management.

The physical design of these modules adheres to Cisco's standards, ensuring easy installation and hot-swappable capabilities. This means network administrators can replace or upgrade the modules without taking the entire system offline, providing greater flexibility and reducing downtime.

In summary, Cisco's PA-FE-TX and PA-FE-FX modules are integral components for organizations seeking to enhance their networking infrastructure. With their support for both copper and fiber optic connections, they provide versatile options for connecting devices, extending network reach, and improving data transfer speeds. Their compatibility with advanced networking technologies further emphasizes Cisco's commitment to delivering high-quality, reliable networking solutions for businesses of all sizes.
