1. 1. Save the current configuration.

DellEMC#write memory

1. 1. Delete the CDB files (confd_cdb.tar.gz.version and confd_cdb.tar.gz).

DellEMC#delete flash://confd_cdb.tar.gz.version
DellEMC#delete flash://confd_cdb.tar.gz

1. 1. Reload the system.

DellEMC#reload

VXLAN Scenario

In a VXLAN scenario, hybrid port is not supported.

Deploying System in Normal-Reload Mode with BMP Configuration

If you are deploying the system in the normal-reload mode with BMP configuration, use the following command at the beginning ofthe startup configuration if the write memory command is used at the end of the configuration:

ip ssh server enable

REST API Authentication

REST API does not support AAA authentication.

Non-Dell Qualified Cables and Optics

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 40Gtransceivers. If you insert a non-Dell qualified 40G transceiver
into a S4048-ON 40GbE port, the switch places the interface in an error- disabled (operationally down) state and generates a syslogmessage.

To verify the error-disabled status of an interface, enter any of the following show commands:

New Dell Networking OS Version 9.14(1.12) Features
The following features have been added to the S4048-ON with Dell Networking OS version 9.14(1.12):
None.

Restrictions

• If you downgrade the Dell Networking OS version from 9.14(1.12) to 9.11(0.0) or any older version, 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.

• 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 40G transceivers. If you insert a non-Dell qualified 40G transceiver into a S4048-ON 40GbE 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.

• 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)

• 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
Following default behavior and CLI syntax changes occurred during the Dell Networking OS release:

• To enhance security, the default RSA key size has been changed to 2048 bits from 1024 bits from 9.14.1.10 onwards.
