Introduction

The Cisco Nexus 9000 Series NX-OS 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 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.

When choosing an EPLD version for upgrade, ensure you have already installed the corresponding NXOS software version first. It is generally not supported to upgrade to a newer EPLD image built for a future version of NXOS while running on an older NXOS version, unless explicitly supported as per the specific EPLD Release Notes. NXOS and EPLD images are labeled for their related version to avoid any unsupported upgrades.

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, then consider postponing the upgrade until a better time.

Note: The EPLD upgrade operation is a disruptive operation. 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.

Note: EPLD version is backward compatible. The NXOS software can be downgraded for the switch and the EPLD version does not have to be downgraded to match the older NXOS version.

Switch Requirements

·       The Cisco Nexus 9000 Series switch must be running the Cisco NX-OS operating system.

·       You must be able to access the switch through a console, SSH, or Telnet (required for setting up a switch running in NX-OS mode).

·       You must have administrator privileges to work with the Cisco Nexus 9000 Series switch.

EPLD Upgrades Available for NX-OS Mode Releases 9.3(14)

Each EPLD image that you can download from Software Download page, is a bundle of EPLD upgrades pacjkaged into a single EPLD image file. To see the recent updated EPLD versions for the Cisco Nexus 9200, 9300, 9300-EX, 9300-FX, and 9500 platforms, see these tables.

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.

Note: The 9.3(14) release of EPLD, addresses the Secure Boot Hardware Tampering vulnerability for the Nexus 3K and Nexus 9000 Series switches. Please refer to Security Advisory.

 

Please review the advisory for affected hardware product identification (PIDs). See table for more details on how to apply the patch. The 9.3(14) release EPLD requires a specific sequence of upgrade.

Vulnerable Products addressed in Security Advisory (cisco-sa-20190513-secureboot)

Nexus 9000 Series Switches

 

Note: N3K-C36180YC-R and N3K-C3636C-R, CPU FPGA will have the fix, so look for CPU FPGA instead of IO.

Cisco Secure Boot Hardware Tampering Vulnerability - Remediation Steps

This section details updating your EPLD version for affected switches listed in: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot

Nexus 9000 Modular chassis with dual supervisor

 

IMPORTANT NOTE:
It is required to update both Golden and Primary regions of FPGA to address this particular vulnerability. It is by design that we don't allow updating both primary and golden at the same time (to avoid programming errors, that may cause switch to not boot, so only one region is allowed to be programmed per reload).

 

Please do not attempt to upgrade Golden region of FPGA once it is on a fixed version.

 

1.     Copy the EPLD image to bootflash (e.g., used n9000-epld.9.3.14.img).

2.     If you have dual supervisor, determine which is the standby Supervisor by doing 'show module' and start upgrading it first. On the N9K, only supervisors need upgrade for this vulnerability. LC/FM/SC cards are not affected.

3.     Assuming standby supervisor is slot 28, update the Primary FPGA region of standby supervisor.

 

    install epld bootflash:n9000-epld.9.3.14.img module 28

 

Expected result: Switch will update primary EPLD of standby supervisor and will reload the standby supervisor module automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening. Once standby is booted, it will again come up as standby supervisor.  A 'show version module 28 epld' will continue to show old version.

 

switch# show mod | grep SUP

27   0    Supervisor Module                     N9K-SUP-A             active *

28   0    Supervisor Module                     N9K-SUP-A             ha-standby

27   9.3(0.416)               1.0    SUP1

28   9.3(0.416)               0.3011 SUP2

 

switch# show version module 28 epld

EPLD Device                     Version

---------------------------------------

IO FPGA                          0x27 

 

This is expected, as the switch would have booted from Golden FPGA which is still not updated. You can verify this from syslog which would say:

 

%CARDCLIENT-5-MOD_BOOT_GOLDEN: Module 28 IOFPGA booted from Golden

 

4.     Update the Golden (also called backup) FPGA region of the standby supervisor.

 

install epld bootflash:n9000-epld.9.3.14.img module 28 golden

 

Module 28 : IO FPGA [Programming ] : 100.00% (64 of 64 total sectors)

Module 28 EPLD upgrade is successful.

Module        Type  Upgrade-Result

------  ------------------  --------------

    28         SUP         Success 

 

Expected result: Switch will update the golden EPLD of standby supervisor and will reload the standby supervisor module automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening. Once standby is booted, it will again come up as ha-standby supervisor.

Once this is done, when you check 'show version module 28 epld' you will see FPGA version that is >= to the fixed version for the standby supervisor.  Your switch has the fixed version for standby supervisor. 

 

switch# show version module 28 epld

 

 

EPLD Device                     Version

---------------------------------------

IO FPGA                          0x30

 

Repeat Step 3 and  4, for the active supervisor. At the end of Step 3, supervisor in slot 27 will reload and will become standby supervisor. The active supervisor will be Supervisor in slot 28. 


(considering SUP 27 is active to begin with, for the above activity, such as Steps 3 and 4, commands would have 27 in place of 28.) 

 

Log below shows what happens when EPLD upgrade happens for active supervisor.

 

Module 27 : IO FPGA [Programming] : 100.00% (64 of 64 sectors)

Module 27 EPLD upgrade is successful.

Module        Type  Upgrade-Result

------  ------------------  --------------

    27         SUP         Success

 

 

EPLDs upgraded. Performing switchover.

 

Once the supervisor in Slot 27 becomes ha-standby, complete step 4 for Slot 27. It will again boot and become ha-standby.  Both the supervisors now have the vulnerability fixed version of FPGA.

 

At the end of the upgrades, switch should boot with primary for both SUPs, logs below

 

switch# show logging log | grep -i fpga | grep -i 27

2019 Jul 10 07:55:04 switch %CARDCLIENT-5-MOD_BOOT_PRIMARY: Module 27 IOFPGA booted from Primary

switch# show logging log | grep -i fpga | grep -i 28

2019 Jul 10 07:58:01 switch %CARDCLIENT-5-MOD_BOOT_PRIMARY: Module 28 IOFPGA booted from Primary

 

Nexus 9000 Modular chassis with single supervisor

 

IMPORTANT NOTE:
It is required to update both Golden and Primary regions of FPGA to address this particular vulnerability. It is by design that we don't allow updating both primary and golden at the same time (to avoid programming errors, that may cause switch to not boot, so only one region is allowed to be programmed per reload).

 

Please do not attempt to upgrade Golden region of FPGA once it is on a fixed version.

 

1.     Copy the EPLD image to bootflash (e.g., used n9000-epld.9.3.14.img).

2.     Assuming the supervisor is in Slot 27. Update the Primary FPGA region.

 

install epld bootflash:n9000-epld.9.3.14.img module 27

 

Expected result: Switch will update  primary EPLD of the supervisor and will reload the switch automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening. Once the supervisor is booted, the 'show version module 27 epld' will continue to show old version

 

Switch#show version module 27 epld

-------------------------------------------------------------------

Name                     InstanceNum           Version        Date

-------------------------------------------------------------------

IO FPGA                          0              0x27       20160111

BIOS version                     v08.35(08/31/2018) 

Alternate BIOS version           v08.32(10/18/2016)

 

 

This is expected, as the switch would have booted from Golden FPGA which is still not updated. You can verify this from syslog which would say:

 

%CARDCLIENT-5-MOD_BOOT_GOLDEN: Module 27 IOFPGA booted from Golden

 

3.     Since in this case there is only one supervisor, update the Golden (also called backup) FPGA region.

 

install epld bootflash:n9000-epld.9.3.14.img module 27 golden

 

Module 27 : IO FPGA [Programming ] : 100.00% (64 of 64 total sectors)

Module 27 EPLD upgrade is successful.

Module        Type  Upgrade-Result

------  ------------------  --------------

    27         SUP         Success

 

 

Expected result: Switch will update  the golden EPLD of the supervisor and will reload the switch automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening.

Once this is done, when you check ‘show version module 27 epld' you will see FPGA version that is >= to the fixed version for the supervisor. Your supervisor has the vulnerability fixed version of FPGA.

 

SWITCH# show version module 27 epld

BIOS version                     v08.35(08/31/2018) 

Alternate BIOS version           v08.32(10/18/2016) 

 

At the end of the upgrades, switch should boot with primary for the SUP, log below

 

switch# show logging log | grep -i fpga | grep -i 27

2019 Jul 10 07:55:04 switch %CARDCLIENT-5-MOD_BOOT_PRIMARY: Module 27 IOFPGA booted from Primary

 

IMPORTANT NOTE:

If you attempt to upgrade the Golden region of the FPGA once it is on the fixed version, the system will not automatically allow you to upgrade the Golden region of SUP, and will provide this prompt:

 

switch# install epld bootflash:n9000-epld.9.2.5.img module all golden

Module 28 (EPLD ver 0x30) Golden upgrade not supported                     

The above modules require upgrade.                                         

Since both System Controller modules need an upgrade,a chassis reload will happen at the end of the upgrade.

IMPORTANT NOTE:
It is required to update both Golden and Primary regions of FPGA to address this particular vulnerability. It is by design that we don't allow updating both primary and golden at the same time (to avoid programming errors, that may cause switch to not boot, so only one region is allowed to be programmed per reload).

 

Please do not attempt to upgrade Golden region of FPGA once it is on a fixed version.

 

1.     Copy the EPLD image to bootflash (e.g., used n9000-epld.9.3.14.img).

2.     Update the Primary FPGA region.

 

    install epld bootflash:n9000-epld.9.3.14.img module 1

 

 

Expected result: Switch will update EPLD and will reload automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening. Switch would boot up with golden FPGA, ‘show version module 1 epld’ would show the old FPGA version for IO, due to this. This is expected.

BIOS version                     v01.14(06/15/2019) 

Alternate BIOS version           v01.12(07/25/2018)

 

 

You can verify this from syslog which would say:

 

%CARDCLIENT-5-MOD_BOOT_GOLDEN: Module 1 IOFPGA booted from Golden

%CARDCLIENT-2-FPGA_BOOT_GOLDEN: IOFPGA booted from Golden

 

3.     Update the Golden (also called backup) FPGA region.

 

    install epld bootflash:n9000-epld.9.3.14.img module 1 golden

 

Expected result: Switch will update EPLD and will reload automatically. Please don't interrupt, power cycle, or reload when EPLD update is happening.

 

Once this is done, when you check 'show version module 1 epld' you will see FPGA version that is >= to the fixed version.

Determining Whether to Upgrade EPLD Images

If the current EPLD image number for a card is greater than or matches the version expected for your current NXOS software version, you can skip the upgrade.

To determine the EPLD upgrades needed for a Cisco Nexus 9000 Series switch running 9.3(14) software, use the show install impact epld bootflash:<filename> command on that switch, where the filename given is the n9000-epld.9.3.14.img file. First, copy this file to the bootflash to proceed. In this example, the MIFPGA and IOFPGA EPLD images do not need to be upgraded.

Note:   The CLI content in this document is only an example. Your CLI will reflect your hardware.

switch# show install all impact epld n9000-epld.9.3.14.img
Retrieving EPLD versions.... Please wait.

Downloading the EPLD Images

Before you can prepare the EPLD images for installation, download them to the FTP or management server.

1.     From a browser, go to https://software.cisco.com/download/navigator.html.

The browser displays the Cisco website.

2.     Choose Switches.

A list of switch types displays on the right.

3.     Select Data Center Switches.

The right side lists the Data Center Switch product series.

4.     Select Cisco Nexus 9000.

The right side lists the switches in the series that you selected.

5.     Select the switch that you are updating EPLD images for.

The Downloads page opens and lists what you can download for the switch that you selected.

6.     Select NX-OS EPLD Updates.

The Download Software page lists the available EPLD images for the switch.

7.     If you see a new EPLD image for the NX-OS software installed on the switch, click the Download button.

CAUTION: When you are trying to upgrade EPLD, it is recommended to use the same version of EPLD as that of installed software. However, if the installed version of EPLD is already later than the software you are installing, NX-OS software does not allow for the downgrading of the EPLD. Newer EPLD is compatible with older NX-OS software.

8.     Click the link for the file.

The Downloads page displays a Download button and lists information for the file.

9.     Click Download.

The Supporting Documents page opens to display the rules for downloading the software.

10.   Read the rules and click Agree.

A File Download dialog box opens to ask if you want to open or save the images file.

11.   Click Save.

The Save As dialog box appears.

12.   Indicate where to save the file and click Save.

The file saves to the location that you specified.

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. Also be sure that you have an EPLD image file.

Caution: When you are trying to upgrade EPLD, we recommend using the same version of EPLD as that of installed software. However, if the installed version of EPLD is already later than the software you are installing, it is not required to downgrade the EPLD.

■      You can execute an upgrade from the active supervisor module only. This upgrade is for one or all of these:

—     You can upgrade a module individually.

—     You can upgrade all modules sequentially.

—     You can update the images for online modules only.

■      On a Cisco Nexus 9500 platform 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 9500 platform 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 reapply the upgrade to the module that was being upgraded during the interruption.

■      The upgrade process disrupts traffic on the targeted module.

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

1.     Copy the EPLD image file to bootflash.

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.

3.     If you do not need to upgrade the BIOS, set the boot variable using the boot nxos bootflash:n9000-dk9.9.3.14.bin command.

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

5.     If you need to upgrade the BIOS, enter the install all nxos bootflash:n9000-dk9.9.3.14.bin command.

6.     Enter the install epld bootflash:n9000-epld.9.3.14.img module all command.

The switch automatically reboots.

Upgrading the EPLD Images

Caution: When you are trying to upgrade EPLD, we recommended using the same version of EPLD as that of installed software. However, if the installed version of EPLD is already later than the software you are installing, it is not required to downgrade the EPLD.

Verifying the EPLD Upgrades

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

■      To verify updates for a module on a modular switch (Cisco Nexus 9500 platform switches), indicate the chassis slot number for slot-number.
switch# show version module 22 epld

■      To verify updates for a top-of-rack switch (Cisco Nexus 9200, 9300, and 9300-EX platforms), 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.

Limitations

When EPLDs are upgraded, apply these guidelines and observations:

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

■      If there are two supervisors that are installed in the switch (Cisco Nexus 9504, 9508, and 9516 switches only), you can either upgrade only the standby or upgrade all modules (including both supervisor modules) by using these 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 that are installed in the switch, your upgrading or downgrading of EPLD images is disruptive.
