Upgrading Routers from Version 5 to Version 10.0

Router Upgrade Prerequisites

Do not begin this router software upgrade process until you verify that the router meets the prerequisites described in this chapter for

• Minimum hardware

• Contiguous free space on a Flash volume

• Boot PROM version

Note:

If you need help meeting the prerequisites of the Version 10.0 router software upgrade procedure as described in this section, contact the Bay Networks Technical Response Center in your area.

Minimum Hardware Requirements

Before you upgrade an AFN, ALN, FN, LN, or CN router to Router Software Version 10.0, perform the following steps to ensure that the router meets all minimum hardware conﬁguration and revision level requirements:

Ensure that the VME router you want to upgrade contains a Flash memory controller and a Flash card.

1-2

To determine whether your VME router contains a Flash memory controller, look at Slot 1 in the router module. The Flash memory controller resides in this slot.

Version 10.0 router software runs on Flash media only.

Note:

The PCMCIA/Floppy switch on a SYSCON-II Flash controller should

be in the Floppy position, with the router running Version 5.

Complete any planned (optional) upgrade from 2-MB Flash to 4-MB

software.

Flash support on a router.

This procedure includes a Boot PROM upgrade for a Flash controller module.

Determine whether any other new router hardware requires software or PROM upgrades to work properly.

Contiguous Free Space on a Flash Volume

You must determine the amount of free space that you need on the Flash card to accommodate the customized Version 10.0 router software image and conﬁguration ﬁles. The amount of contiguous free space available on the target Flash volume must be greater than the combined size of the customized Version

10.0 router software image and associated ﬁles (such as appropriate, a Version 10.0 PROM image).

After you ﬁrst boot the Flash card that contains the default determine the amount of contiguous free space available in a selected volume

Boot PROM Version

Starting with Version 8.10 of the router software, Bay Networks implemented a new naming convention for router software image ﬁles in AN™, AFN (with Flash), ASN™, and BN for FN, ALN, LN, and CN routers remains

The new naming convention provides the following beneﬁts:

• Simpliﬁes how you manage router software image ﬁles on your Site Manager

workstation, beginning with Version 8.10.

• Reduces the complexity of performing future upgrades in a network

containing different routers.

Upgrading Routers from Version 5 to Version 10.0

Upgrade the Boot PROM in the router when you want to implement the new naming convention and an y new features that depend on the newest version of the Boot PROM program.

Note:

Bay Networks strongly recommends that you upgrade the Boot and Diagnostic PROMs in an AFN (Flash) router before upgrading the router’s software image to Version 10.0. The Version 10.0 software requires a Version

• You know how to back up the Version 5 router software and ﬁles.

• You have a working knowledge of the operating system and the windowing

software on the UNIX workstation or PC you will use to run Site Manager software.

• You have a 4-MB Flash card on which to store the Version 10.0 router

software image and associated ﬁles. A 2-MB Flash card will no longer accommodate the Version 10.0 router software image and associated ﬁles.

1-6

• You have considered minimum hardware revisions (for example, a link

module with hot-swap capability may require a hardware revision for Version

10.0).

• You have considered your memory requirements carefully. Based on the

number of protocols installed on your router, you may require additional memory to run these protocols.

If you have questions regarding memory requirements, contact the Bay Networks Technical Response Center in your area.

• You have read these Bay Networks publications:

Verifying X.25 Certiﬁability

If the router you want to upgrade does not currently support any X.25 conﬁgurations, go to “Reviewing Interoperability Issues.”

If you need to upgrade a Version 5 router supporting X.25 to a Version 10.0 router supporting X.25, read this section.

Due to possible differences between older and newer link modules supporting connections to your X.25 network, you must verify that a Version 5 router you want to upgrade to Version 10.0 can meet X.25 certiﬁcation requirements. If you have not done so before receiving this upgrade kit, you may need to replace some link modules so that the router passes X.25 certiﬁcation.

Refer to Appendix B for information on the hardware you need to ensure that the routers you are upgrading meet X.25 certiﬁcation requirements upon completion of the upgrade.

Reviewing Interoperability Issues

Before you upgrade from Version 5 to Version 10.0, review the following interoperability issues between Version 5 and Version 10.0 routers:

Preparing to Upgrade

• Point-to-point connections over a synchronous line

• PPP software

• AppleTalk OUI values for routing over SMDS or Frame Relay

Note: You do not need to remove features unsupported in Version 10.0 from a

Version 5 conﬁguration ﬁle.

Refer to Appendix B for more detailed information about these issues, then go to Chapter 2 or 3 to begin the router upgrade process.

Chapter 2

Starting the Upgrade:

Copying Files to Your Personal Computer

This chapter describes how to install or copy the following ﬁles to a personal computer (PC):

• Site Manager Version 4.0 ﬁles

• Router Software Version 10.0 ﬁles

• Version 5 router ﬁles For instructions on how to copy these ﬁles to a UNIX Site Manager workstation,

go to Chapter 3.

Task 1: Installing the Site Manager Software

Follow the instructions provided in Quick-Starting Routers and BNX Platforms to install your Version 4.0 Site Manager software and Distinct 3.31 TCP/IP software on a PC.

Site Manager on the PC uses a Windows Socket-compatible TCP/IP stack to communicate across the IP network. Before you can upgrade Site Manager 4.0 on your PC, you must ﬁrst upgrade the TCP/IP stack on that PC. Site Manager ships with the Distinct TCP/IP for Microsoft Windows software, Version 3.31, a Distinct Corporation application. Distinct TCP/IP provides an interface between Site Manager and the TCP/IP network. Earlier versions of Distinct TCP/IP will not work with Site Manager 4.0 for the PC.

If you use another Windows Socket-compatible TCP/IP stack to support Site Manager, refer to the user documentation supplied by the manufacturer of the TCP/IP stack for installation instructions.

2-1

Upgrading Routers from Version 5 to Version 10.0

Task 2: Installing the Router Software

Follow the instructions provided in Modifying Software Images for Routers to install Version 10.0 router software on a Site Manager PC.

Task 3: Backing Up Version 5 Files from Router to PC

Bay Networks recommends that you back up to your PC the software image and conﬁg ﬁles currently stored on the router. It is important to maintain backup

copies of these ﬁles to ensure that you can restore router operation in case you encounter malfunctions during the upgrade process.

You back up Version 5 ﬁles to your Site Manager PC via diskette or via the IP network. (In Chapter 4, you use the backup copy of your Version 5 router conﬁguration ﬁle as the source for the conversion utility convert.exe.) Choose the ﬁle backup or transfer method most appropriate for your requirements.

Transferring Files via Diskette

You can physically transport the router diskette with Version 5 conﬁguration ﬁles to your Site Manager PC, then copy the ﬁles to the local hard drive. Perform the following steps:

2-2

1. Enter the following Network Control Language (NCL) command at the

operator’s console of the router you want to upgrade:

remove

Remove the diskette from the diskette drive of the router.

3. Insert the router diskette into the diskette drive of the PC.

4. Copy all ﬁles from the router diskette to the desir ed directory on y our PC

Starting the Upgrade: Copying Files to Your Personal Computer

When you ﬁnish transferring ﬁles from the router to your PC, go to Chapter 4.

Transferring Files via the Network

You can transfer (back up) Version 5 ﬁles from the router to your Site Manager PC via your IP network using a TFTP-capable application program running on your PC. When you use the TFTP-capable program, be sure to

• Use the IP address of your router as the host address for the TFTP operation.

• Copy all the ﬁles (including those within directories) from the router diskette volume to the desired directory on your PC hard drive using binary-mode GET ﬁle operations.

For example, transfer the ﬁles to the \wf\v580.bkp directory, where v580 is the version of your router software.

For instructions on how to perform a TFTP binary-mode GET ﬁle operation from your Site Manager PC, refer to the user documentation supplied by the manufacturer of your TFTP-capable software.

Table 2-1 lists the Version 5 ﬁles you must transfer (back up) from the router’s default ﬁle system volume to your PC.
