NSE-100 Memory Information Chapter 1 NSE-100 Overview • Main memory for Parallel eXpress Forwarding (PXF)-Stores the tables for PXF routing and other PXF features. On the NSE-100, IP traffic, with a few exceptions, is always forwarded using PXF. • Packet memory-Used for packet buffering by the router's network interfaces. • Flash memory-Stores the boot helper image software. The boot helper image allows you to boot the router when the CompactFlash Disk does not contain a valid system image. It also allows you to boot the router from a network server. • CompactFlash Disk (disk0:)-Stores the Cisco IOS software image and any other data that is stored in Flash memory. On the NSE-100, the router CLI refers to the CompactFlash Disk slot on the NSE-100 faceplate as disk0:. • CompactFlash Disk (bootdisk:)-Stores the boot helper image software. The boot helper image allows you to boot from the router when the CompactFlash Disk in disk0: does not contain a valid system image. It also allows you to boot the router from a network server. • Boot one time programmable (OTP) read-only memory (ROM)-Performs power-on diagnostics and initialization; initiates system bootup based on virtual configuration register. Contains the ROM monitor boot image, which permits you to boot the Cisco IOS image from either bootflash or a CompactFlash Disk. The boot OTP ROM cannot be upgraded; ROM can be upgraded using upgradeable boot ROM, also called the "golden ROM" for Cisco 7304 routers in some Cisco documentation. • Upgradeable boot ROM-The upgradeable boot ROM performs the same functions as the boot OTP ROM, but is upgradeable. If the boot code is upgraded, the upgraded boot code is stored in upgradeable boot ROM. Note Boot ROM is upgraded using the Cisco IOS software. Boot ROM cannot be upgraded by physically changing a component on the NSE-100 board. • Nonvolatile random-access memory (NVRAM)-Stores the system configuration, environmental monitoring logs, and the virtual configuration register.

NSE-100 Overview

NSE-100 Memory Information

•

Main memory for Parallel eXpress Forwarding (PXF)—Stores the tables for PXF routing and other

PXF features. On the NSE-100, IP traffic, with a few exceptions, is always forwarded using PXF.

•

Packet memory—Used for packet buffering by the router’s network interfaces.

•

Flash memory—Stores the boot helper image software. The boot helper image allows you to boot

the router when the CompactFlash Disk does not contain a valid system image. It also allows you to

boot the router from a network server.

•

CompactFlash Disk (disk0:)—Stores the Cisco IOS software image and any other data that is stored

in Flash memory. On the NSE-100, the router CLI refers to the CompactFlash Disk slot on the

NSE-100 faceplate as disk0:.

•

CompactFlash Disk (bootdisk:)—Stores the boot helper image software. The boot helper image

allows you to boot from the router when the CompactFlash Disk in disk0: does not contain a valid

system image. It also allows you to boot the router from a network server.

•

Boot one time programmable (OTP) read-only memory (ROM)—Performs power-on diagnostics

and initialization; initiates system bootup based on virtual configuration register. Contains the ROM

monitor boot image, which permits you to boot the Cisco IOS image from either bootflash or a

CompactFlash Disk. The boot OTP ROM cannot be upgraded; ROM can be upgraded using

upgradeable boot ROM, also called the “golden ROM” for Cisco 7304 routers in some Cisco

documentation.

•

Upgradeable boot ROM—The upgradeable boot ROM performs the same functions as the boot OTP

ROM, but is upgradeable. If the boot code is upgraded, the upgraded boot code is stored in

upgradeable boot ROM.

Note

Boot ROM is upgraded using the Cisco IOS software. Boot ROM cannot be upgraded by

physically changing a component on the NSE-100 board.

•

Nonvolatile random-access memory (NVRAM)—Stores the system configuration, environmental

monitoring logs, and the virtual configuration register.
