Rele ase 10.1(1) became available.

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 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.

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(4) through 10.1(1)

Each EPLD image that you can download from Software Download page, is a bundle of EPLD upgrades. To see the recent updated EPLD versions for the Cisco Nexus 9200, 9300, 9300-EX, 9300-FX, and 9500 platforms, see the following 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 10.1(1) 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 HW-PIDs (see below table) for more details on how to apply the patch. The 10.1(1)) release epld requires a specific sequence of upgrade.

Cisco Secure Boot Hardware Tampering Vulnerability - Remediation Steps

The following 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:

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, hence 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.10.1.1.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.10.1.1.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.9.3.1.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 hence now will be-come 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, and 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:

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, hence 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.10.1.1.img).

2.     Assuming the supervisor is in Slot27. Update the Primary FPGA region.

install epld bootflash:n9000-epld.10.1.1.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.10.1.1.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

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

Name                     InstanceNum           Version        Date

IO FPGA                          0              0x30       20190625

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 al-low you to upgrade the Golden region of SUP, and will provide the following prompt:

 

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

Module 27 (EPLD ver 0x29) Golden upgrade not supported                     

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.

Nexus 9000 and Nexus 3000 TOR:

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, hence 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.10.1.1.img).

2.     Update the Primary FPGA region.

install epld bootflash:n9000-epld.10.1.1.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.

show version module 1 epld

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.10.1.1.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.

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

After uprade is complete, switch should boot up with primary, shown logs below

show logging log | grep -i fpga

2019 Jul  9 19:46:11 Deervalley4 %CARDCLIENT-2-FPGA_BOOT_PRIMARY: IOFPGA booted from Primary

2019 Jul  9 19:46:11 Deervalley4 %CARDCLIENT-2-FPGA_BOOT_PRIMARY: MIFPGA booted from Primary

2019 Jul  9 19:46:11 Deervalley4 %CARDCLIENT-5-MOD_BOOT_PRIMARY: Module 1 IOFPGA booted from Primary

2019 Jul  9 19:46:11 Deervalley4 %CARDCLIENT-5-MOD_BOOT_PRIMARY: Module 1 MIFPGA booted from Primary

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

Determining Whether to Upgrade EPLD Images

EPLD image number, you can skip the upgrade.

      To determine the EPLD upgrades needed for a Cisco Nexus 9000 Series switch, use the show install impact epld bootflash: command on that switch and indicate the n9000-epld.10.1.1 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.10.1.1.img

Retrieving EPLD versions.... Please wait.

Images will be upgraded according to following table:

Module  Type   EPLD              Running-Version   New-Version  Upg-Required

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

     1    LC  MI FPGA                   0x0f        0x0f             No

     1    LC  IO FPGA                   0x0d        0x0d             No

     1    LC  DB FPGA                   0x0e        0x0e             No

    21    FM  IO FPGA                   0x07        0x07             No

    27   SUP  IO FPGA                   0x15        0x15             No

    28   SUP  IO FPGA                   0x15        0x15             No

    29    SC  IO FPGA                   0x20        0x20             No

    30    SC  IO FPGA                   0x20        0x20             No

Compatibility check:

Module        Type         Upgradable        Impact   Reason

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

     1             LC           Yes       disruptive   Module Upgradable

    21            SUP           Yes       disruptive   Module Upgradable

    27            SUP           Yes       disruptive   Module Upgradable

    28            SUP           Yes       disruptive   Module Upgradable

    29             SC           Yes       disruptive   Module Upgradable

    30             SC           Yes       disruptive   Module Upgradable

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 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 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 that are installed in the switch, your upgrading or downgrading of EPLD images is disruptive.
