Introduction

The Cisco Nexus 3000 Series NX-OS mode switches that run Cisco Nexus 9000 Series NX-OS software contain several programmable logical devices (PLDs) that provide hardware functionalities in all modules. Cisco provides electronic programmable logic device (EPLD) image upgrades to enhance hardware functionality or to resolve known issues. PLDs include electronic programmable logic devices (EPLDs), field programmable gate arrays (FPGAs), and complex programmable logic devices (CPLDs), but they do not include ASICs. In this document, the term EPLD is used for FPGA and CPLDs.

The advantage of having EPLDs for some module functions is that when you need to upgrade those functions, you just upgrade their software images instead of replacing their hardware.

NOTE: EPLD image upgrades for a line card disrupt the traffic going through the module because the module must power down briefly during the upgrade. The system performs EPLD upgrades on one module at a time, so at any one time the upgrade disrupts only the traffic going through one module.

Cisco provides the latest EPLD images with each release. Typically, these images are the same as provided in earlier releases but occasionally some of these images are updated. These EPLD image updates are not mandatory unless otherwise specified. The EPLD image upgrades are independent from the Cisco In Service Software Upgrade (ISSU) process, which upgrades the system image with no impact on the network environment.

When Cisco makes an EPLD image upgrade available, these release notes announce their availability, and you can download the EPLD images from https://software.cisco.com/download/navigator.html.

Deciding When to Upgrade EPLDs

When new EPLD images are available, the upgrades are always recommended if your network environment allows for a maintenance period in which some level of traffic disruption is acceptable. If such a disruption is not acceptable at this time, then you might consider postponing the upgrade until a better time.

NOTE: The EPLD upgrade operation is a disruptive operation. You should execute this operation only at a programmed maintenance time. The system ISSU upgrade is a nondisruptive upgrade.

NOTE: Do not perform an EPLD upgrade during an ISSU system upgrade.

Switch Requirements

The Cisco Nexus 3000 Series switch must be running the Cisco NX-OS operating.

You must have administrator privileges to work with the Cisco Nexus 3000 Series switch.

EPLD Upgrades Available for NX-OS Mode Releases 7.0(3)I5(1) through 7.0(3)I7(1)

Each EPLD image that you can download from https://software.cisco.com/download/navigator.html is a bundle of EPLD upgrades. To see the recent updated EPLD versions for the Cisco Nexus 3000 Series switches running Cisco Nexus 9000 NX-OS software, see the following table.

NOTE: All updates to an image are shown in boldface. If more than one release is shown for a column, the boldface applies to the first release listed for the column.

Determining Whether to Upgrade EPLD Images

To determine which devices need upgraded EPLDs, use the show install impact epld bootflash: command for a device and indicate the latest EPLD image file (n9000-epld.7.0.3.I7.1.img). The output for this command indicates the current EPLD images, new EPLD images, and whether the upgrades would be disruptive to switch operations. If the currently installed EPLD version number is greater than the new EPLD image number, you can skip the upgrade.

·         To determine the EPLD upgrades needed for a Cisco Nexus 3000 Series switch, use the show install impact epld bootflash: command on that switch and indicate the n9000-epld.7.0.3.I7.1 image. In the following example, the MIFPGA and IOFPGA EPLD images do not need to be upgraded.

switch# show install all impact epld n9000-epld.7.0.3.I7.1.img

What to Do Next

You are ready to prepare the EPLD images for Installation.

Installation Guidelines

To upgrade the EPLD images using CLI commands, follow these guidelines:

·         Before you upgrade any EPLD images, be sure that you have updated the Cisco NX-OS operating system to the level required for the images and be sure that you have an EPLD image file.

CAUTION: Do not install EPLD images for a release later than the installed release (the EPLD image number must be the same as the number for the installed software release or it must be an earlier release number). The Cisco Nexus 3000 and 9000 Series switches support only the images for the current or earlier releases.

·         If you interrupt an upgrade, you must reapply the upgrade to the switch that was being upgraded during the interruption.

·         The upgrade process disrupts traffic on the targeted switch.

·         Do not insert or remove any modules while an EPLD upgrade is in progress.

Step 1

·         Copy the EPLD image file to bootflash.

Step 2

·         To determine if you need to upgrade the BIOS for the image, use the show install all impact command and see the Upgrade Required (Upg-Required) field for the BIOS row in the command output.

Step 3

·         If you do not need to upgrade the BIOS, set the boot variable using the boot nxos bootflash:n9000-dk9.7.0.3.I7.1.bin command.

Step 4

·         Enter the copy running-config startup-config command to set the startup boot variables to the NX-OS image.

Step 5

·         If you need to upgrade the BIOS, enter the install all nxos bootflash:n9000-dk9.7.0.3.I7.1.bin command.

Step 6

Enter the install epld bootflash:n9000-epld.7.0.3.I7.1.img module all command.

·         The switch automatically reboots.

Upgrading the EPLD Images

CAUTION: Do not install EPLD images for a release later than the installed release. The Cisco Nexus 3000 Series switches support only the images for the current or earlier releases.

Procedure

Verifying the EPLD Upgrades

To verify the EPLD upgrades for a switch or its modules, use the show version module slot-number epld command as follows:

·         To verify updates for a top-of-rack switch, use 1 for slot-number.

switch# show version module 1 epld

Displaying the Status of EPLD Upgrades

To display the status of EPLD upgrades on the switch, use the show install epld status command.
