New Dell Networking OS Version 9.14(2.14) Features

The following features are integrated into the Dell Networking 9.14.2 branch through this release: Non

Restrictions

• You can use non-Dell qualified cables, adapters, and optics in a S4048-ON switch, but Dell Networking does not guarantee their performance as the S4048-ON does not support non-Dell qualified transceivers of 25G and above. If you insert
  a non-Dell qualified transceiver of 25G and above into a SFP28, QSFP+, or QSFP28 port, the switch places the
  interface in an error-disabled (operationally down) state and generates a syslog message, such as: %S4048LC0640:8 %IFAGT-2-TRANSCEIVER_UNSUPPORTED_ERROR: Transceiver in slot 1 port 49 unrecognized, putting interface in operational-down state.
  To verify the error-disabled status of an interface, enter any of the following show commands.

• Prerequisite steps to upgrade the Dell Networking OS from earlier version to 9.14.2.0 or later:

  • Uninstall the older version of the Open Automation (OA) package

  • Upgrade the Dell Networking OS to 9.14.2.0 or later version

  • Install the 9.14.2.0 version or later of the OA packages :

  • SmartScripts

  • Puppet

  • Open management infrastructure (OMI)

  • SNMP MIB
    Prerequisite steps to downgrade the Dell Networking OS from 9.14.2.0 or later to the earlier version:

  • Uninstall the 9.14.2.0 or later version of the OA package

  • Downgrade the Dell Networking OS to an earlier version

  • Install the respective OA package from an earlier version
    For more information about installing, uninstalling and upgrading the Dell Networking OS and OA package, refer the respective Dell System Release Notes.

• If you downgrade the Dell Networking OS version from 9.14.2.14 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:

• In a VXLAN scenario, hybrid port is not supported.

• 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 Networking OS:

  • 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)

• You can use the negotiation auto command to turn auto-negotiation on or off only on fiber interfaces operating at 1G speed.

• If you use a 1 G SFP, disable autonegotiation on both peer ends. If you do not disable autonegotiation, the link does not come up.

• 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.

• Do not configure the vxlan-instance command on the port, which is configured with the portmode hybrid command. Do not configure the vxlan-instance enabled port as a member of VLAN, which does not have VXLAN-VNI configuration.

Changes to Default Behavior and CLI Syntax

The following behavior and CLI changes are applicable to the S4048–ON switch with Dell Networking OS version 9.14(2.14): None

Documentation Corrections
This section describes the errors identified in the current release of the Dell 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.
