Downloading Software and Firmware
Introduction
This chapter provides information for downloading software and firmware, describes where to obtain it, and details the required preparations and procedures for downloading software and firmware from the CWM workstation to a Cisco WAN switch.
The Image Downloader is a Java-based application and feature of Release 11 of CWM. The Image Downloader allows you to download software and firmware images, and to monitor the download process, as described at the end of this chapter.
The TFTP/FTP protocol is used to download software and firmware images from the CWM workstation to WAN switches.

Where to Get Switch Images for Downloading
Cisco Connection Online (CCO) provides a web page, WAN Switching Upgrade Planner, that provides information about the latest Cisco software product. If you have a Cisco Connection Online account, you can order or download software directly to your system. The URL for CCO software and firmware is:
//www.cisco.com/kobayashi/sw-center/wan/wan-planner.shtml
The WAN Switching Upgrade Planner web page provides links to the following:

Preparing the IPX/BPX Switch to Download Software or Firmware
Before downloading software and firmware to a switch, use the Switch CLI (Command Line Interface) to execute the following commands. This is required regardless of how the software image transfer will be initiated.
Note
Step 1
When you select the switch node from the CWM Network Topology window and then select the Node menu's Node Admin option, the CWM software telnets to the switch. A new terminal window is displayed for your use.
Step 2
cnffunc
Step 3
cnffunc <index> e
In the example, <index> would be set to 6. The "e" parameter specifies to enable the function. Once this command is executed, the switch allows downloading from a CWM workstation, provided the latter is connected to another switch in the same network.
Step 4
cnfnodeparm
shows sample output from the cnfnodeparm command. When a redundant processor card (BCC, NPM, or NPC) is not installed, you should set the parameter indicating the presence of a redundant processor to No. In the command output, look for the number corresponding to the CC Redundancy Cnfged entry.
Step 5
cnfnodeparm <number> N
When you have a redundant processor card and the value for the parameter CC Redundancy Cnfged is Yes, you are requesting an image download into both processors (active and redundant).

Step 6
cnffwswinit <IP_addr_CWM_workstation>

Downloading Switch Software or Firmware from the CWM Workstation to a Switch
To download images to an MGX, complete the following steps:
Step 1
Step 2
Step 3
The Image DownLoader window is displayed. This window displays a list of the software that is loaded on the CWM workstation (in the /usr/users/svplus/images/ directory) for the type of node selected.Choose the image you wish to download, then select Download.
When the download has completed, please telnet to the switch and use the switch CLI to verify and invoke the images.
Note
Image Filename Conventions
The following naming conventions are used for software images:
IGX and BPX Conventions
IGX and BPX software images have the following format (where Release is 9.2.0):
IGX and BPX firmware images have the following format:
MGX Conventions
The following naming convention is used for software images:
<cardtype>_<A>_<B> [<C>_<D>].fw
where <cardtype> is a name of the card. <A>, <B>, <C>, and <D> can be a string containing any combination of numerals and characters. <A>_<B> <C>_<D> indicates the firmware version number of a given image file. <C> and <D> are optional. The .fw extension indicates the file is a firmware image.
Monitoring a Download Session on BPX and IGX Nodes
The commands dsprev (software) and dspfwrevs (firmware) display existing software (or firmware) revisions on a routing network, as well as the revisions currently being downloaded. When these commands are issued at a feeder, revisions on that feeder alone appear on the screen.
You can use the dsprev or dspfwrevs commands to see when downloading of the software or firmware is complete.
Image Downloader
The Image Downloader is a feature of Release 11 of CWM that allows you to download software and firmware images. Select Tools from the CWM Network Topology's tool bar and then select SW/FW Images from the drop down menu to launch the Image Downloader application.
The Image Downloader GUI contains two tab views: In-Progress and Image Download. The In-Progress tab view, shown in Figure 12-1, contains information about the on going image download processes.

The Download feature is used to transfer the configuration data file from CWM workstation to the switch; the Restore feature is used to transfer the configuration data file to the switch and to restore all of the configurations that are based on this data.
