Introduction

The Cisco Nexus 9000 Series ACI-mode switches 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 an I/O module 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 ACI In Service Software Upgrade (ISSU) process, which upgrades the system and kickstart images 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 them from http:/​/​www.cisco.com.

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/kickstart ISSU upgrade is a nondisruptive upgrade.


Note

Do not perform an EPLD upgrade during an ISSU system/kickstart upgrade.

Switch Requirements

Determining Whether to Upgrade EPLD Images

You can use the show install impact epld bootflash: command to determine whether the EPLDs can be upgraded for all the modules or for specific modules on a switch. This command indicates the current EPLD images, new EPLD images, and whether the upgrades would be disruptive to switch operations.

The following example shows the results of using the show install impact epld bootflash: command on a Cisco Nexus 93xxx switch. In this case, the MI FPGA and IO FPGA EPLD images can be upgraded for the switch supervisor (slot 1) and the MI FPGA2 EPLD image can be upgraded for the supervisor in the uplink module (slot 2). Both upgrades are disruptive.

What to Do Next

You are ready to prepare the EPLD images for Installation (see Upgrading the EPLD Images).

Installation Guidelines

You can upgrade EPLDs using CLI commands on the Cisco Nexus 9000 Series switch. Follow these guidelines when you upgrade EPLDs:

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

  • You can execute an upgrade from the active supervisor module only. This upgrade is for one or all of the modules as follows:

    • You can upgrade a module individually.

    • You can upgrade all modules sequentially.

    • You can upgrade all modules in parallel.

  • You can update the images for one or all modules whether the switch is online or offline as follows:

    • If the modules are online, only the EPLD images with version numbers that differ from the new EPLD images are upgraded.

    • If the modules are offline, all of the EPLD images are upgraded.

  • On a Cisco Nexus 95xx switch that has two supervisor modules, upgrade the EPLDs for the standby supervisor and then switch the active supervisor to the standby mode to upgrade its EPLDs (the supervisor switchover is not disruptive to traffic on Cisco Nexus 95xx switches). On a switch that has only one supervisor module, you can upgrade the active supervisor, but this will disrupt its operations during the upgrade.

  • If you interrupt an upgrade, you must upgrade the module that is being upgraded again.

  • The upgrade process disrupts traffic on the targeted module.

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

Upgrading the EPLD Images

If you have a Cisco Nexus 9000 Series switch that is running Cisco NX-OS Release 6.1(2)I1(3) build or later build, follow the special upgrade steps presented here.

Procedure
Step 1   Copy the n9000-dk9.7.0.3.I1.2.bin and n9000-epld.7.0.3.I1.2.img images 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 boot flash:n9000-dk9.7.0.3.I1.2.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.I1.2.bin command.
Step 6   Enter the install epld bootflash:n9000-epld.7.0.3.I1.2.img module all command to upgrade the EPLD. The chassis will reboot automatically.

Verifying the EPLD Upgrades

You can verify the EPLD upgrades for each slot in a modular switch by using the command the show version module slot_numberepld command.

Displaying the Status of EPLD Upgrades

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

Limitations

When EPLDs are upgraded, the following guidelines and observations apply:

  • If a module is not online, you cannot upgrade its EPLD images.

  • If there are two supervisors installed in the switch (Cisco Nexus 9504, 9508, and 9516 only), you can either upgrade only the standby supervisor from the active supervisor or upgrade all modules (including both supervisor modules) by using the following commands:

    • install epld bootflash: image module standby_supervisor_slot_number (upgrades only the standby supervisor module)


      Note

      After you use this command, you can switchover the active and standby supervisor modules and then upgrade the other supervisor.

    • install epld bootflash: image module all (upgrades all of the modules)

  • If there is only one supervisor installed in the switch, your upgrading or downgrading of EPLD images is disruptive.
