Using the EXEC Command Interpreter

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC. You must enter the privileged level of the EXEC command interpreter (also called enable mode) with the enable command before you can use the configure command to configure a new interface or to change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket

(>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#

If you installed a new PA-FE or if you want to change the configuration of an existing interface, you must enter configuration mode using the configuration command. If you replaced an interface that was previously configured, the system recognizes the new interface and brings it up in its existing configuration.

Identifying Chassis Slot, Port Adapter Slot, and PA-FE Interface Port Numbers

The following section describes how to identify the chassis slot, port adapter slot, and PA-FE interface port numbers for Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series universal broadband routers, and the VIP2.

Cisco 7200 Series and Cisco uBR7200 Series Ports

Physical port addresses specify the actual physical location of each interface port on the router. On Cisco 7200 series routers and Cisco uBR7200 series universal broadband routers, this address is composed of two parts in the format port adapter slot number/interface port number, as follows:

•The first number identifies the slot in which the PA-FE is installed.

•The second number identifies the interface port on the PA-FE, which is always numbered as interface 0.

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.
