Cisco 12000 Series Routers

Field Notice: Cisco 12000 Requires More Than 20MB Flash Memory With IOS Images 12.0(31)S and Later


November 08, 2004


Products Affected

  • 12.0(31)S

Problem Description

The Cisco 12000 Series Giga-Bit Route Processor (GRP-B) was shipped with a default 20MB flash card used as non-volatile memory to store IOS images and configuration files.

This route processor is no longer being manufactured and was replaced by PRP-1 and PRP-2 that ship with larger default flash card sizes.

With the newly added features into IOS releases, the 20MB card can no longer contain the image starting IOS 12.0(31)S, thus a larger flash memory is needed.

Background

Features and Benefits

The large capacity Flash disk card supports larger or multiple configuration files and Cisco IOS Software images. Cisco IOS Software memory requirements are available on Cisco.com on the Software Center (registered customers only) page.

Software Requirements

The 64MB card is supported on the 12000 family of routers starting IOS 12.0(17)S/ST.

For more details on Cisco IOS Software releases that support the 64-MB use the Hardware-Software Compatibility Matrix.

Problem Symptoms

Customers with Cisco 12000 GRP route processors must upgrade their flash memory to 64MB or larger if they want to upgrade the IOS to release 12.0(31)S and later.

Workaround/Solution

Customers who already have GRP-B or any other RP card with 20M cards and wish to run IOS 12.0(31)S and later must purchase 64M or larger flash card upgrades.

Note:?The Performance Route Processors (PRP-1, PRP-2) are currently shipped with the 64M Flash Disk as default. It is recommended to verify that the customer is not using the 20M flash on PRP-1.
