Supported Software

The following software is supported with this platform:

Software	Minimum Release Requirement
Dell EMC Networking OS	9.14(2.11)
ONIE	3.27.1.10–0

For information on non-Dell OS versions, see the Release Notes for the Hardware Platform S4048T–ON.

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:

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:

CDB boot error: C.cdb file format

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:

DellEMC#write memory
DellEMC#delete flash://confd_cdb.tar.gz.version
DellEMC#delete flash://confd_cdb.tar.gz
DellEMC#reload

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.
You can use non-Dell qualified cables, adapters, and optics in a S4048T-ON switch, but Dell EMC Networking does not guarantee their performance as the S4048T-ON does not support non-Dell qualified 40G transceivers. If you insert a non-Dell qualified 40G transceiver into a S4048T-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.

DellEMC# show inventory media
Slot Port Type Media Serial Number F10Qualified
——————————————————————–
1 49 UNKNOWN UNKNOWN USC1D6J No**
1 50 QSFP 40GBASE-LR4 UQ90C7B No**
1 51 QSFP 40GBASE-SR4 7503835V009Y Yes
1 52 QSFP 40GBASE-CR4 10190002 No
1 53 QSFP 40GBASE-SR4 FE2429470007 Yes
1 54 Media not present or accessible
** Interface is down(error disabled) as transceiver is not F10Qualified

DellEMC# show interfaces fortyGigE 1/49
fortyGigE 1/49 is up, line protocol is down( error-disabled[Transceiver Unsupported] )
…

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)
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 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
REST API does not support AAA authentication.
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.
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

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.
