New Dell EMC Networking OS Version 9.14(2.9) 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 9.14.2.0 version or later of the OA packages : 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 9.14.2.0 or later version of the OA package

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 9.14.2.9 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.

● REST API does not support AAA authentication.

● You can use non-Dell qualified cables, adapters, and optics in a S4048-ON switch, but Dell EMC 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.

Dell# show inventory media Slot Port Type Media Serial Number DellQualified

------------------------------------------------------------------- 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 DellQualified

Dell# 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:

○ 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.
