Introduction

The Cisco Multi-Processor WAN Application Module (MWAM) is a Cisco IOS application module that you can install into the Catalyst 6500 series switch. The module allows you to run multiple instances of Cisco Mobile Wireless applications, such as the Cisco Packet Data Serving Node (PDSN), or the Cisco Mobile Wireless Home Agent (HA). Other applications will be added in future releases.

Each MWAM card contains three processor complexes (PCs), with two CPUs each, that are used to run IOS. Each CPU can be used to run an independent IOS image. The interfaces used by these IOS instances are gigabit ethernet 802.1Q trunk ports, which carry VLAN encapsulated traffic to and from the network through the Catalyst 6500 switch fabric. Each processor complex (housing two IOS instances) shares one gigabit ethernet interface.

Currently, an MWAM card running either PDSN or HA can run up to five instances of IOS simultaneously. Each MWAM card is dedicated to run one function only, PDSN or HA. The Catalyst 6500 chassis can house up to six MWAM cards.

The implementation of the MWAM running the Cisco PDSN or Mobile Wireless Home Agent requires the following components:

•Cisco Multi-Processor WAN Application Module

•Cisco IOS Release 12.2(9)ZA on the Catalyst 6500 Series Supervisor 2/MSFC2

•Cisco 6509 Catalyst Switch

•A IPSec VPN Acceleration Services Module for IPSec services (required only for IPSec)

•Cisco IOS Release 12.2(8)ZB that contains either the PDSN or Mobile Wireless Home Agent applications

---

Note If you plan to deploy IPSec services, be aware that the IPSec VPN Acceleration Services Module requires 512-MB DRAM on the MSFC2

---

System Configuration Requirements

The MWAM requires the following system configuration:

•Cisco IOS 12.2(9)ZA Supervisor image be installed on the Supervisor Engine 2.

Refer to the Release Notes for Cisco IOS Release 12.2(9)ZA on the Catalyst 6500 Series and Cisco 7600 Series Supervisor Engine and MSFC for specific information about the Supervisor Engine 2.

Refer to the Cisco Multi-Processor WAN Application Module Installation and Configuration Notes for specific information about configuring the MWAM.

Memory Requirements

The Catalyst 6500 series MWAM memory is not configurable.

Supported Hardware

Before you can use the Catalyst 6500 series MWAM Module, you must have a Supervisor Engine 2 with an MSFC 2, and any module with ports to connect server and client networks.

---

Note Release 12.2(9)ZA does not support OSMs or the FlexWAN module because of open caveats CSCdx94072, CSCdx83584, CSCdx57576, CSCdx60406, CSCdx69921, and CSCdx63685.

Determining the Software Version

To determine the version of Cisco IOS software copied on the RPM-PR, access the CLI of the RPM-PR and enter the show version command:

router# show version

     Cisco Internetwork Operating System Software 

     IOS (tm) MWAM Software (MWAM-JS-M), Version 12.2(9)ZA, EARLY DEPLOYMENT RELEASE 

     SOFTWARE (fc1)

Loading and Maintaining Images

The Supervisor II must have a Cisco IOS running on the Supervisor Engine 2 and MSFC that supports the MWAM. The Catalyst Operating System image is not supported. For more information on the Supervisor II for the MWAM, refer to the following publication:

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/relnotes/122_8ZA.htm

The application software bundle is copied to the Processor Complex compact flash for use by the MWAM. This process involves booting the MWAM card from the MP partition, using the standard IOS copy command to store the image in the compact flash card, and then resetting the MWAM to load the new image. All IOS images on the MWAM card will be the same.

Loading the IOS Image to MWAM

The image download process automatically loads an IOS image onto the three Processor complexes on the MWAM. Complexes 1 and 2 will run two instances of the same IOS image, and Complex 0 will run one instance of the same IOS image.

Upgrading the Image

---

Note The total time to upgrade the image can be as much as 30 minutes.

---

To upgrade an Application image, you will need a compact flash card that has the MP partition from the current image (or later), and a recent supervisor image. To locate the images, please go to the Software Center at Cisco.com (http://www.cisco.com/public/sw-center/).

To perform the upgrade perform the following tasks:

	Command	Purpose
Step 1	Router# hw module mod reset cf:1	Boots the maintenance partition (MP) on the module.
Step 2	Router# show module	Verify that the MP has booted.
Step 3	Router# copy tftp:absolute-path/filename pclc#slot-fs:	Downloads the application image to the MWAM through the supervisor engine console. Note The upgrade file uses a special format that makes this process slow.
Step 4	Router# hw module mod reset cf:4	Reboot the MWAM card back to partition cf:4 and you have an upgraded image.

This example show how to upgrade the MWAM image:

Router# hw module 4 reset cf:1

Router# show module

Router# copy tftp:absolute-path/filename pclc#4-fs:

Upgrade has started

Do not reset the card till upgrade is complete

Upgrade is complete

You can reset the blade

---

Caution In order to know when it is safe to reboot the MWAM card, Cisco recommends that you globally configure the logging console command on the supervisor so that you can see all of the output detail of the upgrade procedure.

---

Upgrading a Spare MWAM Card

---

Note Spare MWAM cards boot directly to the MP, rather than the AP. You first need to acquire a software license for the application, and then install the software on the MWAM.

---

The procedure to upgrade a spare MWAM card is the same as the regular card. The only difference is that instead of manually rebooting to cf:1 (the MP), you will start from there and download and reboot to cf:3.

Upgrading to a New Software Release

For information about copying Cisco IOS images to MWAM memory, see the Cisco Multi-Processor WAN Application Module Installation and Configuration Notes.

For general information about upgrading to a new Cisco IOS software release, refer to Software Installation and Upgrade Procedures located at the following URL:
