Restrictions

• Prerequisite steps to upgrade the Dell EMC Networking OS from earlier version to 9.14.2.0 or later:
  1. Uninstall the older version of the Open Automation (OA) package
  2.  Upgrade the Dell EMC Networking OS to 9.14.2.0 or later version
  3. Install the following OA packages from the respective upgraded version:
     a. SmartScripts
     b. Puppet
     c. Open management infrastructure (OMI)
     d. SNMP MIB

Prerequisite steps to downgrade the Dell EMC Networking OS from 9.14.2.0 or later to the earlier version:

1. Uninstall the OA package of 9.14.2.0 or later version
2. Downgrade the Dell EMC Networking OS to an earlier version
3. Install the respective OA package from an earlier version

For more information about installing, uninstalling and upgrading the Dell EMC Networking OS and OA package, refer the respective Dell EMC System Release Notes.

• If you downgrade the Dell EMC Networking OS version from 9.14.2.11 to 9.11.0.0 or any older versions, the system displays the following error message even though there is no functional impact:

Before downgrading, save the current configuration and then remove the CDB files (confd_cdb.tar.gz.version and confd_cdb.tar.gz). To remove the files, use the following steps

• While deploying the system in the normal-reload mode in BMP configuration, use the ip ssh server enable command at the beginning of the startup configuration if the write memory command is used at the end of the configuration.
• REST API does not support AAA authentication.
• The following features are not available in the Dell EMC Networking OS from version 9.7(0.0):
  • PIM ECMP
  • Static IGMP join (ip igmp static-group)
  • IGMP querier timeout configuration (ip igmp querier-timeout)
  • IGMP group join limit (ip igmp group join-limit)
• Half-Duplex mode is not supported.
• When FRRP is enabled in a VLT domain, no flavor of Spanning tree should concurrently be enabled on the nodes of that specific VLT domain. In essence FRRP and xSTP should not co-exist in a VLT environment.

Changes to Default Behavior and CLI Syntax

• From 9.14(2.4P1) onwards, a new nand chip ships on the S3100 series switch. This chip supports the new UBoot version 5.2.1.10.

Documentation Corrections

This section describes the errors identified in the current release of the Dell EMC Networking OS.

• The router bgp command allows you to configure only one L3 interface with an IPv4 address. The Configuration guide does not mention this limitation and will be corrected in the next release of the guide.

Known S3100 Series 9.14(2.11) Software Issues

The following caveats are open in Dell Networking OS version 9.14(2.11): None.

Upgrade Instructions

The following upgrades are available for the Dell EMC Networking operating system (OS) on S3100 series switches:

1. Upgrade the Dell EMC Networking OS image on S3100 series switches.
2. Upgrade the UBoot from Dell EMC Networking OS.
3. Upgrade the CPLD image.
4. Upgrade the PoE controller.

Upgrading the Operating Software Image

Upgrade the OS image on S3100 series switches by following the procedure in this section.

NOTE: The configurations shown here are examples only and are not intended to duplicate any real system or network.

NOTE: If you installed the Open Automation (OA) package on the S3100 series switch, Dell EMC Networking strongly recommends uninstalling the OA package before you upgrade the Dell EMC Networking OS image. Then reinstall a compatible OA package. In this way, the system installs enhancements and uninstalls incompatible OA packages after the Dell EMC Networking OS upgrade.

NOTE: Dell EMC Networking strongly recommends using the Management Interface to upgrade the new image in both BMP mode and the Upgrade System CLI. Using front-end ports takes more time (approximately 25 minutes) to download and install new image due to the large file size.

NOTE: If you are using bare metal provisioning (BMP), see the Bare Metal Provisioning chapter in the Open Automation Guide

1. Save the running configuration on the switch.
   EXEC Privilege mode

2. Back up your startup configuration to a secure location (for example, an FTP server as shown here). EXEC Privilege mode
   copy startup-config destination
   

3. Upgrade the Dell EMC Networking OS on a S3100 series switch. EXEC Privilege mode
   upgrade system {flash: | ftp: | nfsmount: | scp: | stack-unit: | tftp:| usbflash:} fileurl [A: | B:] Where {flash: | ftp: | scp: | tftp:| usbflash:} file-url specifies the file transfer method and location of the software image file used to upgrade the S3100 series, and is in one of the following formats:

   • flash:// directory-path/filename — Copy from flash file system.
   • ftp:// user-id:password@host-ip/file-path — Copy from remote (IPv4 or IPv6) file system.
   • nfsmount:// mount-point/filepath — Copy from NFS mount file system.
   • scp://user-id:password@host-ip/file-path — Copy from remote (IPv4 or IPv6) file system.
   • stack-unit: — Synchronize image to the specified stack unit.
   • tftp:// host-ip/file-path — Copy from remote (IPv4 or IPv6) file system.
   • usbflash:// directory-path/filename — Copy from USB flash file system
     NOTE: Dell EMC Networking recommends using FTP to copy the new image with the upgrade system command due to the large file size.
     

4. In case of a stack setup, upgrade the Dell EMC Networking OS for the stacked units. EXEC Privilege mode upgrade system stack-unit [1–12 | all] [A: | B:] If A: is specified in the command, the Dell EMC Networking OS version present in Management unit’s A: partition will be pushed to the stack units. If B: is specified in the command, the Management unit’s B: will be pushed to the stack units. Upgrade of stack units can be done on individual units by specifying the unit id [1–12] or on all units by using  all in the command.
   

5. Verify the Dell EMC Networking OS has been upgraded correctly in the upgraded flash partition EXEC Privilege mode
   show boot system stack-unit [1-12 | all] The Dell EMC Networking OS versions present in A: and B: can be viewed for individual units by specifying the stack unit id [1–12] in the command or for all the stack units by specifying all in the command.
   

6. Change the primary boot parameter to the upgraded partition (A: or B:). CONFIGURATION mode
   boot system stack-unit {1-12 | all} {default | primary | secondary} {flash ://file-name | ftp://file-url | system: {A: | B:} | tftp://file-url }
   

7. Save the upgrade configuration so that it is retained after a reload.
   EXEC Privilege mode
   write memory
   

8. Reload the switch so that the Dell EMC Networking OS image is retrieved from flash. EXEC Privilege mode reload
   

9. Verify that the switch is upgraded to the latest Dell EMC Networking OS version. EXEC Privilege mode
   show version
   
   

10. Check if all the stack units are online after reload. EXEC Privilege mode show system brief
    

Upgrade the UBoot from Dell EMC Networking OS

To upgrade the UBoot from Dell EMC Networking OS, perform the following steps:

1. Upgrade the S3100 Series Boot Flash (UBoot) image. EXEC Privilege mode upgrade boot bootflash-image stack-unit [ | all] [booted | flash: | ftp: | scp: | tftp: | usbflash:] Dell EMC Networking OS version 9.14(2.11) requires S3100 Series Boot Flash (UBoot) image version 5.2.1.10. The booted option is used to upgrade the Boot Flash (UBoot) image to the image version packed with the loaded Dell EMC Networking OS image. The Boot Flash (UBoot) image version packed with the loaded Dell EMC Networking OS can be found using the show os-version command in EXEC Privilege mode. To upgrade the Boot Flash image of all stack-units, the option all can be used.
   

2. Reload the unit. EXEC Privilege mode reload
3. Verify the UBoot image. EXEC Privilege mode show system stack-unit <i
   

Upgrading the CPLD

The S3100 series with the Dell EMC Networking OS Version 9.14(2.11) requires System CPLD revision 24.

NOTE: If your CPLD revisions are higher than the ones shown here, DO NOT make any changes. If you have questions regarding the CPLD revision, contact technical support:

Verify that a CPLD upgrade is required

Use the following command to identify the CPLD version:

Use the following command to view CPLD version that is associated with the Dell EMC Networking OS image:

Upgrading the CPLD Image

NOTE: The upgrade fpga-image stack-unit 1 booted command is hidden when using the FPGA Upgrade feature in the CLI. However, it is a supported command and is accepted when entered as documented

NOTE: Ensure that the uBoot version is 5.2.1.8 or above. You can verify this version using show system stack-unit 1 command.

To upgrade the CPLD image on S3100 Series, follow these steps:

1. Upgrade the CPLD image. EXEC Privilege mode
   upgrade fpga-image stack-unit booted
   

2. The system reboots automatically and waits for the DellEMC prompt. The CPLD version can be verified using show revision command output. EXEC Privilege mode show revision

NOTE: Do not power off the system while FPGA upgrade is in progress. For any queries, contact technical support
NOTE: When you upgrade the standby and member units of CPLD, the following message displays in the management unit. The unit automatically reboots once the upgrade is complete and joins the stack with the upgraded CPLD.

Upgrading the PoE Controller

Upgrade the PoE controller image on a stack unit of the S3100 series switch.

1. Upgrade the PoE controller image on a specified stack unit. EXEC Privilege mode upgrade poe-controller stack-unit unit-number
