Chapter 1 Cisco 7200 VXR Product Overview

Field-Replaceable Units

Note

Note

The port adapters installed in the Cisco 7200 VXR routers support OIR. For an explanation of OIR, see the “Online Insertion and Removal” section on page 1-57 .

All port adapters and service adapters connect to two Peripheral Component Interconnect (PCI) buses on the router midplane. The PCI buses provide a path to packet I/O memory and the system (route/switch) processor. The Fast Ethernet port on the I/O controller connects to a third PCI bus for packet routing and switching. The port or service adapters either provide such services as compression or encryption, or they provide network interfaces to connect the router to external networks.

Detailed instructions for removing, replacing, and configuring the port adapter types supported on the Cisco 7200 VXR routers are contained in the configuration note for the port adapter. For example, if you plan to replace a 4-port Ethernet port adapter in your Cisco 7200 VXR router, refer to the configuration note PA-4E Ethernet 10BaseT Port Adapter Installation and Configuration. The configuration note is available on the Documentation DVD and on Cisco.com.

Caution To ensure adequate airflow across the router’s port adapters, a port adapter or a blank port adapter must be installed in each port adapter slot.

The Port Adapter Jacket Card is used in a Cisco 7200 VXR router only with an NPE-G1 or NPE-G2 installed and with no I/O controller. The NPE-G1 has I/O controller functionality, so no I/O controller is needed. The Port Adapter Jacket Card installs in the I/O controller slot, and provides for an additional port adapter slot. The Port Adapter Jacket Card works from a third PCI bus, which provides additional bandwidth and virtually unlimited bandwidth points to the single port adapter slot. For more information, see the Port Adapter Jacket Card Installation Guide.

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
