For more information about this release, see the section Features of 4.2.0 on page 7.

Before You Start

Prior to installing your new software, read these release notes in their entirety. Carefully read the section System Issues and Known Problems on page 9

Updating Your System Software

A new LANplex 2500/2016 comes with Revision 4.2.0 software installed in flash memory. If you are updating software on an existing LANplex 2500/2016 software use the following procedure to update your system software.

You can install a new software version from any host running ftp. The LANplex software is distributed for both UNIX and DOS platforms. The following media typemedia types are used to distribute software releases (the files are compressed on the media):

UNIX tar format 31/2 inch double-sided, high-density 1.44 MB diskette

DOS format 31/2 inch double-sided, high-density 1.44 MB diskette

To update your system software, you must:

Copy the software from the diskette to your UNIX-based or DOS-based computers hard disk.

Load the system software from your computers hard disk to flash memory.

Copying Software to a Hard Disk

You can copy software to either a UNIX-based or DOS-based hard disk.

Copying to UNIX

To copy software to a UNIX hard disk, follow the instructions below:

If the directory /usr/lp2000 does not exist on your computer, create the directory before proceeding. If your /usr directory is full, you can use a different directory. In this case, substitute the actual directory used for /usr in this and subsequent examples.

Insert the diskette containing the LANplex software file into a disk drive (these instructions assume drive fd0).

Copy the LANplex software file to the lp2000 subdirectory of your computer using the following commands:

cd /usr/lp2000

tar xvf /dev/fd0

Decompress the file using the following command:

uncompress lp2000.Z

Copying to DOS

To copy software to a DOS hard disk, follow the instructions below:

If the directory lp2000 does not exist on your computer, create the directory before proceeding.

Insert the diskette containing the LANplex software file into a disk drive (these instructions assume drive B:).

Copy the LANplex software file to the lp2000 directory of your computer using the following commands:

cd lp2000

copy b:lp2000.exe

The files lp2000.exe are self-extracting archives. They decompress and create the loadable lanplex files.

Decompress the file using the following command:

lp2000

This creates a file called lp2000, which you can then load into flash memory.

Updating Your Diagnostic Software

In order to support the new 10BASE-5 (AUI) option module, the diagnostics software must be updated to Revision 2.06. The diagnostics software runs internal tests on the system and option modules on system power up.

It is not necessary to update the diagnostics software to Revision 2.06 for the 10BASE-2 (BNC) option module. However, 3Com recommends that you update the diagnostics software to the latest version.

You can install a new diagnostic software version from any host running ftp. The LANplex diagnostic software is distributed for both UNIX and DOS platforms. The following media typemedia types are used to distribute software releases (the files are compressed on the media):

UNIX tar format 31/2 inch double-sided, high-density 1.44 MB diskette

DOS format 31/2 inch double-sided, high-density 1.44 MB diskette

To update your diagnostic software, you must:

Copy the diagnostic software from the diskette to your UNIX-based or DOS-based computers hard disk.

Load the diagnostic software from your computers hard disk to flash memory.

Copying Software to a Hard Disk

You can copy diagnostic software to either a UNIX-based or DOS-based hard disk.

Copying to UNIX

To copy diagnostic software to a UNIX hard disk, follow the instructions below:

Insert the diskette containing the LANplex diagnostic software file into a disk drive (these instructions assume drive fd0).

Copy the LANplex diagnostic software file to the lp2000 subdirectory of your computer using the following commands:

cd /usr/lp2000

tar xvf /dev/fd0

Decompress the file using the following command:

uncompress LPX2000s.Z

Copying to DOS

To copy software to a DOS hard disk, follow the instructions below:

Insert the diskette containing the LANplex diagnostic software file into a disk drive (these instructions assume drive B:).

Copy the LANplex diagnostic software file to the lp2000 directory of your computer using the following commands:

cd lp2000

copy b:LPX2000S.EXE

The file LPX2000S.EXE is a self-extracting archive. It decompresses and creates the loadable LPX2000S file.

Decompress the file using the following command:

LPX2000S

This creates a file called LPX2000S, which you can then load into flash memory.

New Functionality

The following functionality is added at this release:

IP Routing (LANplex 2500 Only)

At this release, IP routing is implemented in the LANplex system software. IP routing in the LANplex system is composed of the following elements:

IP implemented as described in RFC 791 (Internet Protocol Specification), RFC 1009 (Requirements for Internet Gateways), and RFC 1042 (A Standard for the Transmission of IP Datagrams over IEEE 802 Networks).

ICMP implemented as described in RFC 792 (Internet Control Message Protocol Specification).

RIP implemented as described in RFC 1058 (Routing Information Protocol).

LANplex IP routing:

Provides for high-segmentation routing where multiple ports on the same module can be connected to the same subnet.

Introduces a hierarchical model of bridging/routing where IP frames sent between hosts on segments connected to the same subnet are bridged and IP frames sent between hosts on segments connected to different subnets are routed.

For information about how IP routing is implemented in the LANplex 2500 and how to configure IP routing using the LANplex Administration Console, see the LANplex 2500 Operation Guide and the LANplex 2500 Administration Console User Guide.

Support for the AUI and BNC Option Modules

The LANplex software supports the new 10BASE-5 (AUI) and 10BASE-2 (BNC) option modules. The AUI module supports four (4) female 15-pin, D subminiature, Attachment Unit Interface (AUI) connectors while the BNC module supports 8 BNC connectors. For more information on the AUI and BNC option modules, see the Ethernet 10BASE-5 Module Installation Guide and the Ethernet 10BASE-2 Module Installation Guide.

Known Problems

There are no known problems identified at this release.

System Issues

The following system issues relevant to this release:

When setting Express Switching mode, you cannot select an Ethernet port as the backbone port.

When attaching a modem to the modem port, ensure that the modems terminal speed is set to the same speed as that of the LANplex system.

SNMP MIB Files

SNMP MIB files are shipped with the LANplex system software as ASN.1 files. Copies of ASN.1 files are provided for each of the supported compilers described at the end of this section.

Supported Versions

The SNMP MIB file names and the currently supported version of each MIB are listed below:

bridge.mib Bridge MIB, RFC 1493

ethernet.mib Ethernet MIB, RFC 1398

fddiSmt7.mib FDDI SMT 7.3 MIB, RFC 1512

lp.mib LANplex Systems MIB, version 1.0.1

lpOpFddi.mib LANplex Optional FDDI MIB, version 1.1.5, based on SMT 7.3

mib2.mib MIB-II, RFC 1213

Compiler Support

ASN.1 MIB files are provided for each of the MIB compilers listed below. Any warnings or exceptions related to a particular compiler are listed with that compiler.

SMIC (version 1.0.9)

MOSY (version 7.1)

For the MIB file lpOpFddi.mib, the MOSY compiler reports warnings for counter names that do not end in s. This has no effect on the output produced by the MOSY compiler.

HP Openview (version 3.1)

mib2schema (with SunNet Manager version 2.0)

The MIB file fddiSmt7.mib produces the following warning messages when compiled using mib2schema:

Translating....

fddimibMACSMTIndex
fddimibMACIndex
Translation Complete.
Schema file in fddiSmt7.mib.schema
Oid file in fddiSmt7.mib.oid

However, these warning messages have no effect on the ability of SNM to use the schema file generated with versions of SNM greater than or equal to 2.0.
