Version Description
9.14.0.0 Introduced on the FN-IOM.
Usage Information
This command enables the switch to detect when both stack links fail and shuts down all uplink (external) and
downlink (internal) ports. If a single stack port on a system is down, this command does not shut down ports.
NOTE: Dell EMC Networking recommends disabling UFD when you enable this feature.
Use this command in a stack set up with only three or less units to avoid stack split.
This command is available only in Stack mode of the FN-IOM.
