Introduction

The Cisco Nexus 7000 Series 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 does not provide upgrade EPLD images very frequently, and you do not have to upgrade your EPLD images unless they fix the functions for the hardware that you are using in your Cisco Nexus 7000 Series switch. 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.

Deciding When to Upgrade EPLDs

You do not always need to upgrade EPLD images; however, 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.


Table 2 provides high-level guidelines to help network administrators determine whether an EPLD upgrade is necessary. The Cisco Defect and Enhancement Tracking System (CDETS) listed in this table can be found in the following earlier versions of FPGA/EPLD release notes:

You are ready to prepare the EPLD images for Installation (see the "Preparing the EPLD Images for Installation" section).

EPLD Images Needed for vPCs

The virtual port channel (vPC) feature is available beginning with Cisco NX-OS Release 4.1(3). When you enable vPC on the chassis, you must have EPLD image 186.3 (or later image) on the 32-port 10-Gigabit Ethernet types of I/O modules (N7K-M132XP-12 and N7K-M132XP-12L).


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.


Most of the N7K-M132XP-12 modules in the chassis already meet this minimum EPLD requirement, but if you are working with an N7K-M132XP-12 module that was shipped before June 2008, you might need to upgrade the EPLD version.

To determine the EPLD version for all N7K-M132XP-12 modules, enter the show version module module_id epld. If the line FE Bridge(x) version displays a version earlier than 186.006, you should schedule an EPLD upgrade to a version that is compatible with the target Cisco NX-OS release. For example, if you want to run Cisco NX-OS Release 5.2(1), you should choose Release 5.2(1) EPLDs.

The following example shows Release 186.008 on the FE Bridge line, which is a correct EPLD version:

Nexus-7k(config)# show version module 7 epld 
 
EPLD Device                       Version

Linksec Engine(5)                  2.007 
Linksec Engine(6)                  2.007 
Linksec Engine(7)                  2.007 
Linksec Engine(8)                  2.007 

EPLD Images Needed for LISP

The Locator/ID Separator Protocol ( LISP) feature is available beginning with Cisco NX-OS Release 5.2(1). When you enable LISP on the chassis, you must have EPLD image 186.008 (or later image) on the 32-port 10-Gigabit Ethernet types of I/O modules (N7K-M132XP-12 and N7K-M132XP-12L).


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.


If you are working with an N7K-M132XP-12 module that was shipped before July 2011, you might need to upgrade the EPLD version.

To determine the EPLD version for all N7K-M132XP-12 and N7K-M132XP-12L modules, enter the show version module module_id epld. If the line FE Bridge(x) version displays a version earlier than 186.008, you should schedule an EPLD upgrade to a version that is compatible with the target Cisco NX-OS release. For example, if you want to run Cisco NX-OS Release 5.2(1), you should choose Release 5.2(1) EPLDs.

The following example shows Release 186.8 on the FE Bridge line, which is the correct EPLD version:

Nexus-7k(config)# show version module 7 epld 
 
EPLD Device                       Version

Installation Guidelines

You can upgrade (or downgrade) EPLDs using CLI commands on the Cisco Nexus 7000 Series switch. 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.

You can execute an upgrade from the active supervisor module only. All the modules, including the active supervisor module, can be updated individually.

You can individually update each module whether it is online or offline as follows:

If you upgrade EPLD images on an online module, only the EPLD images with version numbers that differ from the new EPLD images are upgraded.

If you upgrade EPLD images on an offline module, all of the EPLD images are upgraded.

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
...
Software
  BIOS:      version 3.22.0
  kickstart: version 5.2(1) [gdb]
  system:    version 5.2(1) [gdb]
  BIOS compile time:       02/20/10
  kickstart image file is: bootflash:/n7000-s1-kickstart.5.2.1.bin
  kickstart compile time:  12/25/2020 12:00:00 [06/01/2011 04:24:07]
  system image file is:    bootflash:/n7000-s1-dk9.5.2.1.bin
  system compile time:     4/17/2011 3:00:00 [06/01/2011 05:06:22]
 
   

Step 3 Verify that you have 120 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 1-1 to determine the amount of available bootflash memory, and see Example 1-2 to determine the amount of available slot0 memory.

Step 4 If there is not at least 120 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-s1-kickstart.5.2.0.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-s1-epld.5.2.1.img bootflash:n7000-s1-epld.5.2.1.img
 
   

Step 6 Copy the EPLD image to the standby supervisor.

switch# copy bootflash:n7000-s1-epld.5.2.1.img bootflash://sup-standby/n7000-s1-epld.5.2+
.1.img
 
   

You are ready to upgrade the EPLD images (see the "Upgrading the EPLD Images" section).

Upgrading the EPLD Images

You can 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 "Determining Whether to Upgrade EPLD Images" section.

To upgrade the EPLD images for a Cisco Nexus 7000 Series switch, you use one of the install commands listed in Table 5. 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).

Table 5 EPLD Upgrade Commands  

Modules Upgraded
Command

All installed modules with one module upgraded at a time

install all epld epld_image

All installed modules with the I/O modules upgraded in parallel

install all epld epld_image parallel

One or more I/O and supervisor modules with the I/O modules upgraded in parallel

install all epld epld_image parallel module {all | slot_numbers}

One or more I/O and supervisor modules with the I/O modules upgraded in parallel and one or more fan-tray modules

install all epld epld_image parallel module {all | slot_numbers} fan-module {all | slot_numbers}

One or more I/O and supervisor modules with the I/O modules upgraded in parallel and one or more fabric (xbar) modules

install all epld epld_image parallel module {all | slot_numbers} xbar-module {all | slot_numbers}

One or more fan-tray modules and one or more fabric (xbar) modules

install all epld epld_image parallel fan-module {all | slot_numbers} xbar-module {all | slot_numbers}

One I/O or supervisor module

install module slot_number epld epld_image

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.

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

This example shows how to start the installation of all new EPLD images for all modules in a switch:

switch# install all epld bootflash:n7000-s1-epld.5.2.1.img parallel

This example shows how to start the installation of all new EPLD images for all of the I/O and supervisor modules and the fan-tray module in fan-tray slot 1.

switch# install all epld bootflash:n7000-s1-epld.5.2.1.img parallel module all fan-module 1

For Release 4.0(2) or earlier releases, if you updated the power management EPLD image, you must reset the power for the module so that EPLD can take effect (this is not required for release 4.0(3) or later). You can reset the power in one of the following two ways:

To reset the power for the module, physically remove the module and reinstall it.


Note A module reload or just pressing the ejector buttons on the module is not sufficient for this reset requirement.


To reset the entire switch, power cycle the switch.


Caution Resetting the power disrupts any data traffic going through the affected modules. If you power cycle the entire switch, all data traffic going through the switch at the time of the power cycling is disrupted. This is not necessary for Release 4.0(3) or later releases.


Note For Release 4.0(3) and later releases, the switch automatically loads the new power management EPLD after an upgrade, so it is no longer necessary to reset the power for the module or switch.


To confirm the EPLD upgrades, see the "Verifying the EPLD Upgrades" section.

Verifying the EPLD Upgrades

You can verify the EPLD upgrades for each slot in the switch by using the commands listed in table.

Table 1-6

Command
Modules Verified

show version module slot_number epld

I/O and supervisor modules

show version fan slot_number epld

Fan-tray modules

show version xbar slot_number epld

This example shows how to verify the EPLD images for the Cisco Nexus 7018 supervisor module in slot 9:

switch# show version module 9 epld 

This example shows how to verify the EPLD images for the fan-tray module in fan-tray module slot 2:

switch# show version fan 2 epld 

This example shows how to verify the EPLD images for the fabric module in fabric module slot 4:

switch# show version xbar 4 epld 

Displaying the Available EPLD Versions

To view the available EPLD versions, use the show version epld url command as shown in Example 1-3.

Limitations

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

You cannot upgrade the Local Bus CPLD and CMP CPLD while you are upgrading a supervisor module in the 4.0(1) release only.

You must upgrade each installed module individually. If the module is online, Cisco NX-OS upgrades only the EPLD images that have different current and new versions. If the module is offline, all EPLDs are upgraded, even if their version numbers are the same.

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.

Release 4.1(2) does not provide EPLD upgrades for the Cisco Nexus 7018 fan controller.
