Chapter 1 Overview

Identifying Interface Addresses

Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-19, Figure 1-20, Figure 1-21, and Figure 1-22.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-4.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The PA-2FE is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a dual-port PA-2FE is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface addresses would be 3/1/0 and 3/1/1.

Note Although the processor slots in the seven-slot Cisco 7507 and the thirteen-slot Cisco 7513 chassis are vertically oriented and those in the five-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series routers use the same method for slot and port numbering.

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.
