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
● 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

| Connectivity |
Gigabit Ethernet ports: Three 10/100/1000 ports are available on the NPE-G1. Either copper or fiber is available. 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. |
| Processor and Memory | |
| Processor | 700 MHz Broadcom BCM1250 processor. |
| Memory (SDRAM) |
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. |
| Memory (Flash/Cache) |
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). |
