The VoQ IMM Enabled status in the fpga-tables vqf-voq-stats output from the CLI remains 0 indefinitely resulting in traffic loss between blades.

Traffic loss from the blade reporting the zero values for IMM Enabled towards the destination blade. The destination blade is indicated by the first number in the decimal of the "NAME" column. For instance, if the IMM ENABLED values are 0 for "Slot 3 and NAME "13.12", this indicates that traffic from slot 3 towards slot 13 will be lost.
A temporary loss of the dataplane links between the system controller and a blade on a system, followed by an extensive outage for that blade to the confD database.
Reboot the blades reporting the IMM Enabled values of 0.
None
