Release Notes

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:
Dell#write memory
Dell#delete flash://confd_cdb.tar.gz.version
Dell#delete flash://confd_cdb.tar.gz
Dell#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.
● 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.
● The following features are not available in the Dell 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.
● When 1024 or more VNI profiles are configured, the system takes more time to load. Dell 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
● 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.
Changes to Default Behavior and CLI Syntax
● If you are upgrading from an earlier OS9 version to 9.14.2.x, ensure you first upgrade to version 9.13.0.0 before upgrading to
the required version of 9.14.2.x to prevent any issues during the upgrade procedure.
