Introduction

The Cisco Nexus 7000 Series switches, which include the Cisco Nexus 70xx and 77xx 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 NX-OS 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.

The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on

age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on standards documentation, or language that is used by a referenced third-party product.

Deciding When to Upgrade EPLDs

You do not always need to upgrade EPLD images but the following circumstances do require that you upgrade these images:

- If you are enabling software features that require EPLDs.

- If you are using M2 Series 100-Gbps Ethernet I/O modules that remain powered down after booting up the switch.

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 non disruptive upgrade.

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

Table 2 provides high-level guidelines to help network administrators determine whether an EPLD upgrade is necessary when upgrading the Cisco NX-OS Release 5.0(1) or later releases. If you are upgrading an earlier release, see one of the following earlier versions of the FPGA/EPLD release notes:

- Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 4.0

- Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes, Release 4.1

Table 2 Conditions For Upgrading EPLD Images

Condition

Modules Recommended for Upgrades 1

Upgrading Supervisor 2 E from any Cisco Nexus N77xx device to Cisco Nexus N7702 device for Release 7.2(0)D1(1).

Upgrade the EPLD to (1.004) 20.0.

Upgrading the Cisco NX-OS operating system from Release 4.x to Release 5.0 or later releases.

Update all supervisor, I/O, and fabric modules with the latest EPLD images.

1.We recommend (not mandatory) that you upgrade the EPLD images for the supervisor, I/O, and fabric modules.

Switch Requirements

The Cisco Nexus 7000 Series switch must be running the Cisco NX-OS operating system and include the following hardware:

- Supervisor modules—one or two, each with at least 140 MB of available bootflash or slot0 memory

- I/O modules—at least one

- Fabric modules—at least three (Cisco Nexus 7009, 7010, 7018, 7706, 7710, and 7718 only)

- Fan trays

– For the Cisco Nexus 7004, one fan tray

– For the Cisco Nexus 7009 chassis, one fan tray

– For the Cisco Nexus 7010 chassis, two system fan trays and two fabric fan trays

– For the Cisco Nexus 7018 chassis, two fan trays

– For the Cisco Nexus 7702 chassis, one fan tray

– For the Cisco Nexus 7706, 7710, and 7718 chassis, three fan trays

You must be able to access the switch through a console, SSH, or Telnet.

You must have administrator privileges to work with the Cisco Nexus 7000 Series switch.

EPLDs Available for Releases 8.x

Each EPLD image that you can download from https://www.cisco.com is a bundle of EPLD upgrades. To see the updated EPLD versions for each release, see the tables provided below (Table 3 to Table 6).

Note Tables 3 to 6 shows EPLD image numbers in X.00y format but the show commands might display these numbers in an older X.y format (without leading zeros) for earlier EPLD images.

Cisco NX-OS Release 8.4(3) includes the following Erasable Programmable Logic Device (EPLD) images:

- n7000-s2-epld.8.4.3.img

- n7700-s2-epld.8.4.3.img

- n7700-s3-epld.8.4.3.img

Cisco NX-OS Release 8.4(2) includes the following Erasable Programmable Logic Device (EPLD) images:

- n7000-s2-epld.8.4.2.img

- n7700-s2-epld.8.4.2.img

- n7700-s3-epld.8.4.2.img

Cisco NX-OS Release 8.4(1) includes the following EPLD images:

- n7000-s2-epld.8.4.1.img

- n7700-s2-epld.8.4.1.img

- n7700-s3-epld.8.4.1.img

Cisco NX-OS Release 8.3(2) includes the following EPLD images:

- n7700-s2-epld.8.3.2.img

- n7700-s3-epld.8.3.2.img

Cisco NX-OS Release 8.3(1) includes the following EPLD images:

- n7700-s2-epld.8.3.1.img

- n7700-s3-epld.8.3.1.img

Note - There are no updates in Nexus 7000 Sup2 EPLD images. Hence n7000-s2-epld.8.3.1.img is not posted to https://www.cisco.com.

- If you decide to upgrade EPLD anyway, or it is determined necessary in your environment, then the following guidelines should be followed.

- EPLD upgrade is not a part of ISSU. When you upgrade from one version to another version, FPGA is not upgraded automatically. You need to trigger EPLD upgrade manually after you upgrade (ISSU) to the target NX-OS release version.

- For Cisco NX-OS Release 6.2(10) and later releases it is recommended to perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).

- For releases prior to Cisco NX-OS Release 6.2(10), you need to first upgrade to Cisco NX-OS Release 6.2(10) or later releases and perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).

- The above guidelines and limitations do not apply to the Nexus 7700 series switches, and their EPLD can be upgraded through the standard process if needed.

Please see CSCvk35999 for more details.

Note To list the EPLDs running on your switch, use the show version module module_number epld command. If any of the versions that you list are older than what is listed in Table 5, we recommend that you update the EPLDs.

Displaying EPLD Images and Versions

The show commands in Table 10 list all EPLD versions available in a module. If any higher versions are available, it is recommended to upgrade to the latest available version.

As shown in Table 10, you can use various show commands to determine whether the EPLDs can be upgraded for all the modules or for specific modules on a switch. These commands indicate the current EPLD images, new EPLD images, and whether the upgrades would be disruptive to switch operations.

Table 10 Displaying the EPLD Upgrade Status for the Switch and its Modules

Installation/Upgrade Guidelines

You can upgrade EPLDs using CLI commands on the Cisco Nexus 7000 Series switch. By default, EPLD images are not downgraded when you downgrade the NX-OS software release because each EPLD image works with older releases of the software.

Note By default, you cannot downgrade EPLD images when you downgrade the NX-OS software release because the EPLD images work with down level versions of the software. For this reason, we do not recommend downgrading EPLD images.

The allow-downgrade option is not supported and it is not available as a command in Cisco NX-OS Release 8.0(1).

Follow these guidelines when you upgrade or downgrade EPLDs:

– 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 one of the following EPLD image files:

Cisco NX-OS Release 8.3(1):

– n7700-s2-epld.8.3.1.img

– n7700-s3-epld.8.3.1.img

Note For EPLDs available for Cisco NX-OS Release 8.3(1), see EPLDs Available for Release 8.x section.

- There are no updates in Nexus 7000 Sup2 EPLD images. Hence n7000-s2-epld.8.3.1.img is not posted to https://www.cisco.com.

- If you decide to upgrade EPLD anyway, or it is determined necessary in your environment, then the following guidelines should be followed.

- For Cisco NX-OS Release 6.2(10) and later releases it is recommended to perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).

- For releases prior to Cisco NX-OS Release 6.2(10), you need to first upgrade to Cisco NX-OS Release 6.2(10) or later releases and perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).

- The above guidelines and limitations do not apply to the Nexus 7700 series switches, and their EPLD can be upgraded through the standard process if needed.

Please see CSCvk35999 for more details.

Cisco NX-OS Release 8.2(1):

– n7000-s2-epld.8.2.1.img

– n7700-s2-epld.8.2.1.img

Cisco NX-OS Release 8.1(1):

– n7000-s2-epld.8.1.1.img

– n7700-s2-epld.8.1.1.img

Cisco NX-OS Release 8.0(1):

– n7000-s2-epld.8.0.1.img

– n7700-s2-epld.8.0.1.img

- 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 on line, 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.

- The install all epld <epld_image> parallel command is used to upgrade all EPLDs at the same time.

- On a system 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 7000 Series 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.

Preparing the EPLD Images for Installation

Before you can update the EPLD images for each of your switch modules, you must determine the Cisco NX-OS version that your switch is using, make sure that there is space for the new EPLD images, and download the images.

To prepare the EPLD images for installation, follow these steps:

Step 1 Log in to the switch through the console port, an SSH session, or a Telnet session.

Step 2 Verify that the switch is using the expected version of the Cisco NX-OS operating system. The kickstart and system lines indicate the Cisco NX-OS version. This step determines the versions of EPLD images that you must download.

switch# show version

_ BIOS: version 8.1.1

_ kickstart: version 8.1(1)

_ system: version 8.1(1)

_ system compile time: 03/1/2017 12:00:00 [03/03/2017 12:33:26]

...

switch#

Step 3 Verify that you have 140 MB of free space on the active or standby supervisor memory devices for the EPLD images that you will be downloading by using the dir bootflash: or dir slot0: commands.

By default, these commands display the used and free memory for the active supervisor. If your switch has an additional supervisor (a standby supervisor), use the show module command to find the module number for the other supervisor, use the attach module command to attach to the module number, and then use the dir bootflash: or dir slot0: command to determine the amount of used and free memory. See Example 2 to determine the amount of available bootflash memory, and see Example 3 to determine the amount of available slot0 memory.

Step 4 If there is not at least 140 MB of memory free for the EPLD files, delete some unneeded files, such as earlier images, so there is enough free memory.

switch# delete bootflash:n7000-s2-kickstart.7.2.0.bin

Step 5 Copy the EPLD image file from the FTP or management server to the bootflash or slot0 memory in the active supervisor module. The following example shows how to copy from the FTP server to the bootflash memory:

switch# copy ftp://10.1.7.2/ n7000-s2-epld.8.1.1.img

bootflash:n7000-s2-epld.8.1.1.img

Step 6 Copy the EPLD image to the standby supervisor.

switch# copy bootflash: n7000-s2-epld.8.1.1.img

bootflash://sup-standby/ n7000-s2-epld.8.1.1.img

You are ready to upgrade the EPLD images (see the “Manual Upgrading of EPLD Images” section).

Manual Upgrading of EPLD Images

You can manually upgrade the EPLD images for either all of the modules installed in your switch or specific modules installed in your switch. When you request an upgrade, the Cisco NX-OS software lists the current and new versions for each EPLD image with the following results:

- If a module is installed and online, the software lists the installed and new versions for each EPLD. Where there is a difference in versions, the software indicates an upgrade or downgrade to occur when you confirm the process.

- If a module is installed and offline, the software cannot list its current EPLD versions so all EPLDs will be updated when you confirm the upgrade.

- If a module is not installed, the software displays an error message and does not upgrade the EPLDs.

If you need to know which modules can be updated and which upgrades are disruptive to switch operations, see the “Displaying EPLD Images and Versions” section.

To upgrade the EPLD images for a Cisco Nexus 7000 Series switch, you use one of the install commands listed in Table 11. These commands enable you to upgrade the EPLD images for all of the modules on the switch, multiple modules of one or two types, or single modules. When specifying a slot_number, use one number. When specifying slot_numbers, you can specify all for all slots, multiple slots separated by commas (x,y,z) or a range of slot numbers (x-y).

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 non disruptive upgrade.

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

Note For details on EPLD upgrade for M1 modules in releases prior to Cisco NX-OS Release 8.0(1), refer to Cisco Nexus 7000 Series FPGA/EPLD Upgrade Release Notes 7.x.

Table 11 EPLD Upgrade Commands

install all epld epld_image parallel module {all | slot_numbers}

One fan module

install fan-module slot_number epld epld_image

One fabric module

install xbar-module slot_number epld epld_image

When you upgrade both supervisor modules in a switch, Cisco NX-OS upgrades the EPLD images for the standby supervisor module and then upgrades the active supervisor module. This action enables the upgrade of supervisor modules to be nondisruptive to switch operations.

Note When upgrading EPLD images for Supervisor 2 or Supervisor 2E modules in a dual-supervisor switch, the standby supervisor will reset twice towards the end of that upgrade but the upgrade continues to completion and the console displays the upgrade status.

When you upgrade supervisor module in a single-supervisor switch, the operation is disruptive to switch operations if the switch is active.

To start the installation of all new EPLD images for all modules in a switch, use the install all epld command as shown in Example 4 (switches with Supervisor 2 or Supervisor 2E modules).

Note When upgrading EPLD images for F3 Series I/O modules, you must upgrade them in parallel by including the parallel keyword with the install command. For example, if you are updating the images for the F3 Series I/O module in slot 2, you use the following command:

switch# install all epld epld_image parallel module 2

Note EPLD and software images for a chassis with Supervisor 2 and Supervisor 2E have “s2” in the image name.

Example 4 Installing EPLD Images in Parallel for Switches with Supervisor 2 or Supervisor 2E Modules

switch# install all epld bootflash:n7000-s2-epld.8.1.1.img parallel

To confirm the EPLD upgrades, see the Verifying the EPLD Upgrades and Downgrades section.

Automatic Upgrading of EPLD Images

You can enable, disable, and verify automatic upgrading of EPLD images for I/O modules installed in the Cisco Nexus 7000 series switches. Also, if the upgrade is canceled because it exceeds a maximum number of programmed attempts, you can reset the process to enable the upgrades.

Note You can set automatic upgrading of EPLD images for only I/O modules, not for other modules such as the supervisor modules, fabric modules, or fan trays.

This section includes the following topics:

- Enabling or Disabling Automatic Upgrades of EPLD Images

- Verifying Automatic Upgrades of EPLD Images

- Resetting Automatic Upgrades of EPLD Images

Enabling or Disabling Automatic Upgrades of EPLD Images

You can enable or disable automatic upgrades of EPLD images for I/O modules. When enabled, the switch checks the EPLD image versions on newly installed or powered up I/O modules to see if they are older than the images that were installed on the switch. If the images on the I/O modules are older, the switch automatically upgrades the images to the newer versions.

SUMMARY STEPS

1. configure terminal

2. system auto-upgrade epld

3. show running-config | inc epld

Note Alternatively, to prevent automatic upgrades of EPLD images for I/O modules, use the no system auto-upgrade epld command.

Limitations

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

- If you interrupt an upgrade, you must upgrade the module again.

- You can execute an upgrade or downgrade only from the active supervisor module. On switches with two supervisors, upgrade the standby supervisor and then switch the standby supervisor to active to place the previously active supervisor module in standby mode. Upgrade the EPLDs on the standby supervisor. On switches that have only one supervisor, you must upgrade or downgrade the EPLDs on the active supervisor, which will interfere with data traffic during the upgrade.
