Date	Description


2021-02	9.14.2.9P1 - Added Fixed Issues for the release.

2020–12	Initial release.

Requirements

The following requirements apply to the Z9100-ON system.

Hardware Requirements

The following lists the Dell EMC Z9100-ON system hardware requirements:

●10/25/40/50/100 GbE switch

●Thirty two fixed quad form-factor pluggable (QSFP28) optical ports

●One each 10/100/100BaseT Ethernet management port, micro universal serial bus (MicroUSB-B) 2.0 console port, USB type A port, and RS-232/RJ45 serial console port

●Two small form-factor pluggable plus (SFP+) 1000M/10G ports

●Two AC or DC power supplies units (PSUs) and five fan subsystem with airflow from the I/O side to the power supply unit (PSU) side or from the PSU side to the I/O side

The following lists the individual Dell Z9100-ON system hardware components that are available to order:

●Fan with airflow from I/O side to PSU side

●Fan with airflow from PSU side to I/O side

●AC or DC power supply with airflow from I/O side to PSU side

●AC or DC power supply with airflow from PSU side to I/O side

NOTE: Fan modules and power supplies are field replaceable units.

NOTE: All fans and PSUs must have the same airflow direction. If you mix the airflow direction, the switch detects the discrepancy, issues an alarm, and may auto-shutdown to avoid heat damage to components. You must correct the mixed airflow direction.

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, see the respective Dell EMC System Release Notes.

●After you upgrade Dell EMC Networking Networking OS to 9.14(2.9) 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(2.9) 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.

●File system partition:

○The ONIE installer, of OS versions 9.11(0.0P4), 9.11(0.1P1), 9.11(0.2), and later, changes the file system partition scheme to facilitate the installation of certain third-party networking operating systems.

○If you have installed Dell EMC Networking OS using the ONIE install option, you cannot downgrade from Dell EMC Networking OS 9.14(2.9) to versions earlier than 9.11(0.0P4), 9.11(0.1P1), or 9.11(0.2), using the upgrade system command, due to file system partition compatibility issues.

NOTE: The above restriction is not applicable if you have upgraded Dell EMC Networking OS using the upgrade system command, instead of the ONIE install option.

●To downgrade Dell EMC Networking OS version 9.14(2.9) to versions earlier than 9.11(0.0P4), 9.11(0.1P1), or 9.11(0.2), follow these steps:

1.From the ONIE menu, use the ONIE uninstall option to uninstall Dell EMC Networking OS 9.14(2.9).

2.Use the ONIE install option to install the older version of Dell EMC Networking OS.

●The systems shipped with OS 9.11(2.3) and above might contain one of the following chipsets:

○BCM56960_B1 chipset with part number 0HW2V or 353W9.

○BCM56960_B0 chipset with part number GTG6M or 2CMPM.

You can check the part number using the show inventory command.

●In a system using BCM56960_B1 chipset, you cannot downgrade from Dell EMC Networking OS 9.11(2.3) to OS versions earlier than 9.10(0.2), due to NPU compatibility issues.

NOTE: The above restriction is not applicable for systems using BCM56960_B0 chipset.

●You cannot use the established keyword in an ACL rule, along with the other control flags.

●While using the established keyword in an ACL rule, all the other TCP control flags are masked, to avoid redundant TCP control flags configuration in a single rule. When you use any TCP control flag in an ACL rule, established is masked and other control flags are available.

●The following features are not available in Dell EMC Networking OS versions 9.14(2.0):

○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.

●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.

2.	Upgrade the GRUB or Bootflash - using the upgrade boot bootflash-image stack-unit 1 booted command.
3.	Upgrade the CPLD - using the upgrade fpga-image system cpld stack-unit 1 booted command.
4.	Upgrade the SMF MSS-IAP - using the upgrade mss-iap-image stack-unit 1 booted command.
5.	Upgrade the SMF MSS-FPGA - using the upgrade mss-fpga-image stack-unit 1 booted command.
6.	Upgrade the OOB-FPGA - using the upgrade fpga-image system fpga stack-unit 1 booted command.

Upgrade the BIOS or Boot Selector

To upgrade the BIOS or Boot Selector from Dell EMC Networking OS, perform the following steps:
