• 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.
• 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)
• 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.
