Hi Zahid_27,
After the fault isolation function of the FES board is enabled, the transmit end that uses the multicast channel detects the fault on the LFES board. If certain conditions are met, the faulty board is isolated from the multicast group. Otherwise, the control board cannot deliver data to other boards.
Therefore, it is recommended that the FES board fault isolation function be enabled.
In V800R011, the NE5000 still supports this function.
