New Dell EMC Networking OS Version 9.14(2.11) Features

The following features are integrated into the Dell EMC Networking 9.14.2 branch through this release: None.

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:

4. Uninstall the OA package of 9.14.2.0 or later version

5. Downgrade the Dell EMC Networking OS to an earlier version

6. 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.

• After you upgrade Dell EMC Networking OS to 9.14(2.11) from an earlier version and update the BIOS using the booted option, the system does not allow you to downgrade the BIOS to an earlier version. To run an earlier BIOS version, use FTP, TFTP, or SCP option from the current OS version.
  

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:

• The following features are not available in Dell EMC Networking OS:
  • Protocol-independent multicast (PIM) equal cost multi path (ECMP)
  • Static Internet group management protocol (IGMP) join (ip igmp static-group)
  • IGMP querier timeout configuration (ip igmp querier-timeout)
  • IGMP group join limit (ip igmp group join-limit)
• When 1024 or more VNI profiles are configured, the system takes more time to load. Dell EMC recommends to restrict the VNI profiles to be less than 1000.
• If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 address command does not display the autoconfig option. You can configure the autoconfig command on individual interfaces.
• If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 nd command displays the
• following options but they do not take effect if you use them:
  • dns-server
  • hop-limit
  • managed-config-flag
  • max-ra-interval
  • mtu
  • other-config-flag
  • prefix
  • ra-guard
  • ra-lifetime
  • reachable-time
  • retrans-timer
  • suppress-ra
• 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.
• On the device, the 48 SFP28 ports are split into 12 port groups; each group constituting four continuous SFP28 ports. Within a port group, all four ports can run at 25G/10G/1G speed. The port group speed is determined by the first optic inserted in any one of the four ports. For example, if you insert an SFP+ in port 1/1, the port group speed is set to 1G/10G. If you insert a 25G optic in port 1/2, the system displays an error message and does not enable the 25G optic. The port group speed resets to the default speed of 25G when you remove the SFP+ from port 1/1.

Changes to Default Behavior and CLI Syntax

The following behavior and CLI changes are applicable to the S4048T–ON switch with Dell EMC Networking OS version 9.14(2.11):
None.

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.
