Chapter 6 NPE-G2 Overview

NPE-G2 Memory Information and Specifications

SDRAM—synchronous dynamic random-access memory.

SDRAM-fixed—SDRAM of a fixed size or quantity; can be replaced, but not upgraded.

SFP module—small form-factor pluggable module.

Unified cache—Instruction cache and data cache are combined. For example, a processor may have primary cache with separate instruction and data cache memory, but unified secondary cache.

USB—universal serial bus.

NPE-G2 Memory Information and Specifications

To determine the memory configuration of your NPE-G2, use the show version command.

The following example shows an NPE-G2 installed in a Cisco 7206VXR router.

PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points. Current configuration on bus mb1 has a total of 780 bandwidth points. The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half bandwidth points" consideration, when full bandwidth point counting results in oversubscription, under the condition that only one of the two ports is used. With this adjustment, current configuration on bus mb1 has a total of 480 bandwidth points.

This configuration is within the PCI bus capacity and is supported under the above condition.

PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points. Current configuration on bus mb2 has a total of 1000 bandwidth points. The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half bandwidth points" consideration, when full bandwidth point counting results in oversubscription, under the condition that only one of the two ports is used. With this adjustment, current configuration on bus mb2 has a total of 800 bandwidth points.

This configuration has oversubscripted the PCI bus and is not a supported configuration.

Please refer to the following document "Cisco 7200 Series Port Adaptor Hardware Configuration Guidelines" on Cisco.com <http://www.cisco.com> for c7200 bandwidth points oversubscription and usage guidelines.

WARNING: PCI bus mb2 Exceeds 600 bandwidth points
