Release Notes for Carrier Module FPGA Image Release 1.8

Release Notes for Carrier Module FPGA Image Release 1.8

April 14, 2000

Catalyst 8540 MSR carrier module FPGA image name fi-c8540-scam.A.1-8

Text Part Number: OL-0178-03 Rev. A0

This document describes the features and caveats for the Cisco field-programmable gate array (FPGA) functional image, fi-c8540-scam.A.1-8, for the carrier modules used with the Catalyst 8540 MSR.

This version of carrier module FPGA image fixes a potential problem with inverse multiplexing over ATM (IMA) port adapters. Previously the IMA port adapter may have failed or become unreliable. This FPGA image fixes caveat CSCdp39313 listed in the "Caveats" section later in this release note.

Contents

This release note includes the following sections:

Introduction

The Catalyst 8540 MSR provides switched ATM connections to individual workstations, servers, LAN segments, or other ATM switches and routers using fiber-optic, unshielded twisted-pair (UTP), and coaxial cable.

Carrier modules allow you to install up to two half-width port adapters in the Catalyst 8540 MSR. Carrier modules used in the Catalyst 8510 MSR, Catalyst 5500, and LightStream 1010 are not interchangeable with carrier modules used in the Catalyst 8540 MSR. Full-width interface modules supported by the Catalyst 8540 MSR do not require installation via a carrier module.

Determining Your Carrier Module FPGA Image Release

This section describes the process you use to determine the existing FPGA functional image version installed on your carrier module.

To display the functional image version in a carrier module, use the following command in privileged EXEC mode:

Command
Purpose

show functional-image-info {slot number | subslot slot/subslot}

Displays the functional image information.

Example

The following example shows the FPGA functional image information for the carrier module in slot 0:

Switch# show functional-image-info slot 0
 
Details for super cam Image on slot: 0
 
Functional Version of the FPGA Image: 1.8

Note   In the previous show function-image-info command the functional version appeared as 1.8 corresponding to the 1-8 string in the file name "fi-c8540-scam.A.1-8."

Updating to a New Release

For detailed FPGA image upgrade instructions, see the "Maintaining Functional Images" section in the "Managing Configuration Files, System Images, and Functional Images" chapter of the ATM Switch Router Software Configuration Guide.

Caveats

This section lists the caveats and corrected caveats for each release. Use the table to determine wether a particular caveat applies to your FPGA functional image release, or wether a particular caveat was corrected in your FPGA or firmware image release. In the table, "Y" indicates a corrected caveat, "N" indicates an open caveat, and "-" indicates the corrected caveat has been carried over from the previous release. These caveats are described in detail in the next section "Caveat Symptoms and Workarounds."

Table 1 lists the known caveats and corrected caveats for this carrier module FPGA image.

Caveat Symptoms and Workarounds

This section describes the closed caveats for this carrier module FPGA functional image.

This carrier module FPGA image fixes the following known DDTSs:

  Symptom: The IMA port adapter might fail or become unreliable.
  Workaround: Upgrade carrier module FPGA image to fi-c8540-scam.A.1-8.
  Symptom: Following a processor card switchover, a number of interfaces are not recognized.
  Workaround: Upgrade carrier module FPGA image to fi-c8540-scam.A.1-7 or later.

  Workaround: Upgrade carrier module FPGA image to fi-c8540-scam.A.1-5 or later.
  Symptom: CBR traffic guarantees are lost when there is an oversubscription of the port.
  Workaround: Upgrade carrier module FPGA image to fi-c8540-scam.A.1-5 or later.
