MCAST/6/FIB:there is no flow in the fib entry (group ip= [STRING], source ip=[STRING] in-VlanID=[ULONG]).


There is no data flow corresponding to the FIB entry.


Parameter Name Parameter Meaning
group ip Indicates the group IP address.
source ip Indicates the source IP address.
in-VlanID Indicates the inbound VLAN ID.

Possible Causes

Multicast services are interrupted. As a result, there is no data flow corresponding to the FIB entry.


  1. Run the display l2-multicast forwarding-table vlan vlan-id command to check the matching Layer 2 multicast forwarding entry has been correctly generated.
  2. Run the display interface brief command to check traffic statistics on the corresponding interfaces are normal.

    If the matching Layer 2 multicast forwarding entry has not been generated or interface traffic statistics are abnormal, join the multicast group again. If multicast services are still interrupted, go to step 3.

  3. Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
