CompactFlash Disks, Flash Disks, and PC Cards

The Cisco 7206VXR supports up to two installed Flash Disks or two PC Cards, also called Flash memory cards. The NPE-G1 supports one CompactFlash Disk, as does the NPE-G2.

Note To avoid potential problems when you install spare Flash Disks or PC Cards in your Cisco 7206VXR, we recommend that you reformat all your Flash Disks or PC Cards on a Cisco 7206VXR that is running the Cisco IOS release recommended for your system (see Table 1-31, Table 1-32, and Table 1-33) during your regularly scheduled service times. The online document Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller explains how to reformat a PC Card.

With Flash memory (Flash Disks, PC Cards, and the Flash SIMM on the I/O controller, or the CompactFlash Disk on the NPE-G1) you can remotely load and store multiple system and boot helper images. You can download a new image over the network, and then add the new image to Flash memory or replace existing files. You can also transfer images between Flash Disks or PC Cards and the onboard Flash memory SIMM. You can then boot the router either manually or automatically from any of the stored images. Flash memory can also function as a TFTP server to allow other routers to boot remotely from stored images or copy them into their own Flash memory.

Note For procedures that explain the use of the Flash Disk or CompactFlash Disk, refer to the online Using the Flash Disk document.

For procedures that explain how to replace the main, Flash, and ROM monitor memory, refer to the Memory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller document. This document is available on the Documentation DVD and on Cisco.com.

For NPE-G2 and NPE-G1 pre-installation information, which requires copying the running configuration from the I/O controller to a Flash Disk or TFTP server before inserting the NPE-G1 into the Cisco 7200 VXR router, see the Network Processing Engine or Network Services Engine Installation and Configuration document at http://www.cisco.com/en/US/products/hw/routers/ps341/products_installation_guide_book09186a008 0551c34.html.

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.
