To continue to meet the increasing needs for performance while maintaining exceptional value and flexibility, the Cisco® 7200 Series introduces its newest processor-the NPE-G1 (Figure 1). The Cisco 7200 Series Network Processing Engine NPE-G1 (NPE-G1) addresses the demand for performance and flexibility by doubling its processing capacity and enabling unprecedented LAN performance. Benefits of the NPE-G1 include the following (see Table 1 for details):
• Provides performance of up to 1 million packets per second (PPS) in Cisco Express Forwarding switching (an increase of up to 250 percent over the Cisco 7200 Series NPE-400)
• Offers three Gigabit Ethernet/Fast Ethernet ports that do not take up bandwidth points
• Doubles the amount of available DRAM (to 1 GB)
• Eliminates the requirement for an input/output (I/O) controller
• Eliminates I/O controller LAN interface bandwidth points
• Provides modular processors and the ability to upgrade
• Offers improved price performance

Table 1. Features and Benefits Overview
Performance of up to 1 million PPS in Cisco Express Forwarding switching
Dramatically increases the performance of the Cisco 7200 Series
3 fixed 10/100/1000-Mbps ports (RJ-45 or gigabit interface converter [GBIC]) directly on the processor
Maximizes LAN connectivity and performance without taking up bandwidth points or midplane capacity
256 MB (default), 512 MB, and 1 GB of DRAM are available
Doubles the amount of DRAM available on the Cisco 7200 Series, which offers the following benefits:
• Supports more routing tables
• Supports more Multiprotocol Label Switching (MPLS) virtual routing and forwarding instances (VRFs)
• Supports more sessions for broadband aggregation
• Enables higher scalability on features such as NetFlow, Network Address Translation (NAT), access control lists (ACLs), and more
Incorporates the functionality (flash memory and auxiliary and console ports) of the I/O controller
Reduces costs (Note: an I/O controller can still be used)
Supports a third peripheral component interconnect (PCI) bus to the I/O controller slot
Frees the current I/O controller ports from bandwidth limitations, allowing 2 PCI buses to be dedicated to the port adapter slots
Enables maximum investment protection through the ability to upgrade processors
Supports Cisco IOS® Software
Supports a wide range of IP network services including quality of service, MPLS, broadband aggregation, security, multiservice, compression, and IPSec Triple Data Encryption Standard (3DES) encryption
PRODUCT SPECIFICATIONS: COMPONENTS
Gigabit Ethernet ports: Three 10/100/1000 ports are available on the NPE-G1 (Figure 2). Either copper or fiber is available.
Figure 2. Cisco 7200 Series NPE-G1 Ports
• Gigabit Ethernet port features: all three ports support the IEEE 802.1Q standard.
• NPE-G1 supports three types of GBICS: SX, LX/LH, and ZX for varying fiber length requirements.
• Console and auxiliary ports: Because the NPE-G1 has a console port and an auxiliary port, and handles the other functionality of the I/O controller, the need for an I/O controller is eliminated. However, an I/O controller can still be used. If an I/O controller is detected in the I/O controller slot, I/O controller functionality defaults to the I/O controller (with the exception of Non-volatile Random Access Memory [NVRAM] and boot flash). The console and auxiliary ports of the NPE-G1 are then disabled.
• SDRAM: 256 MB (default), 512 MB, and 1 GB. There are two DRAM memory slots, so 256 MB of memory consists of two 128 MB memory SODIMMs, 512 MB consists of two 256 MB memory SODIMMs, and 1 GB consists of two 512 MB memory SODIMMs. It is necessary to have the same size SODIMM in each memory bank on an NPE-G1. The type of DRAM memory being used on the NPE-G1 is double data-rate (DDR) memory. DDR memory provides high-performance memory access rates.
• Compact flash: 64 MB (default), 128 MB, and 256 MB. The compact flash used on the NPE-G1 is the same compact flash used with the Cisco 7400 and 7300 series Internet routers.
• 512 KB NVRAM or 512 KB.
• 512 KB Layer 2 cache.
• 16 MB packet memory on 256 MB SDRAM and 32 MB packet memory on 512 MB and 1 GB SDRAM.
• ECC support (SDRAM and Layer 2 cache).
700 MHz Broadcom BCM1250 processor.
