This chapter describes downloading software and firmware from Cisco StrataView Plus (SV+) to an IPX,BPX,IGX, or AXIS node. While there is a brief description of the AXIS procedure, the focus of this chapter is on downloading switch software and firmware images.
You initiate the switch software/firmware download in one of the following manners:
1. From Cisco SV+.
2. From the Switch CLI (Command Line Interface).
3. From any workstation supporting the TFTP (Trivial File Transfer Protocol).
The first method is the easiest and recommended method. This method is described in this chapter. The second and third methods are described in Appendix C "Downloading Software and Firmware From Switch CLI or by TFTP".
The TFTP protocol is used to download Software and Firmware images from the Cisco SV+ workstation to WAN switches.
As the TFTP protocol is used to download images, you need not have a Cisco SV+ workstation to download the images. You are able to load images using any machine that can run a TFTP client/server process.
Switch and Cisco SV+ TFTP download functionality has been implemented for use only on the HP OpenView User Interface. In release 8.4, the Cisco SV+ Network Topology window does not support TFTP download. The Cisco SV+ Network Topology window does continue to support download to switch releases prior to 8.4. See section "Using TFTP to Load Firmware From Sun Workstations Not Running StrataView Plus" in Appendix C for detailed information.
Switch download images can be ordered or downloaded directly to your system when you have a Cisco Connection Online account. The web page for CCO software and firmware download is:
http://www.cisco.com/kobayashi/sw-center/wan/wan-planner.shtml
Figure 11-1 shows the WEB Page for WAN Switching.
Before downloading software and firmware to a switch, use the Switch CLI (Command Line Interface) to execute the following commands.
Step 1 Access the Switch CLI by attaching a dumb terminal to the switch or telnet to the switch.
When you select the switch node from the Cisco SV+ Network Topology window and then select the Node menu's Node Admin option, the Cisco SV+ software telnets to the switch. A new terminal window is displayed for your use.
Step 2 Enable the switch to allow downloading. From the Switch CLI, execute the following command:
cnffunc
Figure 11-2 shows sample output of the cnffunc command.
Step 3 Use the Index column's value for the Download From Remote StrataView entry in the following command:
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 Cisco SV+ workstation, provided the latter is connected to another switch in the same network.
Step 4 Invoke the following command when a redundant processor card is not installed.
cnfnodeparm
Figure 11-3 shows sample output from the cnfnodeparm command. When a redundant processor card (BCC, NTC,PCC) is not installed, you should reset the parameter indicating the presence of a redundant processor. In the command output, look for the number corresponding to the CC Redundancy Configured entry (15 in the sample output).
Step 5 Invoke the following command:
cnfnodeparm <number> N
When you have a redundant processor card and the value for the parameter CC Redundancy Cnfged is Y (yes), you are requesting a simultaneous Image download into both processors (active and redundant).

Step 6 You must set a sufficient hop count on the switch, to allow downloading. The switch to be downloaded may be several hops away from the StrataView Plus Gateway node. Set the hop count parameter on the switch, greater than or equal to the number of hops the switch is from the StrataView Plus Gateway node. Invoke the following command:
cnfdlparm
Figure 11-4 shows sample output from this command.
Step 7 From the output of the previous command, use the hop count number (8) displayed for the Request Hop Limit entry, to set the value of the hop count at the switch:
cnfdlparm <hop_count_ number>
Step 8 In addition to the hop count, you must set values for three other parameters using the cnfdlparm command. Set the values of the Rmt Blk Freq, Lcl Blk Freq, and Image Req Freq parameters to 50.
Step 9 Configure the switch to receive software/firmware images from the Cisco SV+ workstation by invoking the conftwswinit command:
conftwswinit <IP_addr_SV+_workstation>
A step-by-step approach to downloading switch software to another switch from a Cisco SV+ workstation is described in the following sections.
Before initiating the download operation, you must load the software/firmware revisions in the Cisco SV+ workstation's /usr/users/svplus/images/ipxbpx directory.
The procedure for downloading switch software to another switch is as follows:
Step 1 Click on the Topology button in the Cisco SV+ Desktop window.
The Network Topology window is displayed.
Step 2 Click on the node icon in the Network Topology window, upon which you want to download the switch software/firmware, then select the Software Mgmt menu's SW/FW Images option.
The Image Downloader window, shown in Figure 11-5, is displayed. This window displays a list of the IPX, BPX, or IGX software that is loaded on the Cisco SV+ workstation (in the /usr/users/svplus/images/ipxbpx directory) for the type of node selected.
Step 3 In the Image Download window, select the image to download, and then start the image download by clicking on the Download button.
Step 4 Invoke the dsprevs command on the switch CLI from the telnet window. Sample output from this command is shown in Figure 11-6. When the download is complete, the dsprevs command shows the switch is ready.
When you are finished downloading software, you must invoke the runrev command in order to start the downloaded software. When you downloaded firmware, you must invoke the burnfwrev command in order to burn the firmware onto the card. For details about the runrev and burnfwrev commands, refer to the Switch software manuals.
To display the AXIS Image Download window, it helps to understand the basic Network Topology operations. See the description of 8.4 to 8.4 software download in previous sections for information.
To download images to AXIS, follow these steps:
Step 1 Copy your AXIS firmware and software images to the /usr/users/svplus/images/axis directory.
Step 2 Click on the Topology button in the Cisco SV+ Desktop window.
The Network Topology window is displayed.
Step 3 Click on the node icon in the Network Topology window, upon which you want to download the switch software/firmware, then select the Software Mgmt menu's SW/FW Images option.
The Image Downloader window, shown in Figure 11-5, is displayed. This window displays a list of the IPX, BPX, or IGX software that is loaded on the Cisco SV+ workstation (in the /usr/users/svplus/images/ipxbpx directory) for the type of node selected.
Step 4 Select the image you wish to download.
Step 5 Select Download.
Once the download is complete, you must reset the AXIS switch. Follow these steps to perform the AXIS download procedure:
Step 6 Log into the AXIS shelf and issue the resetsys command.
Step 7 After the download completes, reset the AXIS shelf by issuing a resetsys command from the active control card. Upon completion of the resetsys command, the AXIS node switches over to the new software.
The following naming convention is used for software images:
<switchtype>_<A>_<B> [<C>_<D>].sw
where <switchtype> can be one of ipx, bpx, or igx. <A>, <B>, <C>, and <D> can be a string containing any combination of numerals and characters. <A>_<B> <C>_<D> indicates a version number of a given software image file. <C> and <D> are optional. The .sw extension indicates the file is a software image.
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.
