MCAST/4/FIB

Message

MCAST/4/FIB: There is no free FIB index to add a new FIB node. (ForwardingMode=[STRING], ModId=[ULONG], McIndex=[ULONG], DetailInfo=[STRING])

The number of multicast forwarding entries reaches the maximum, so no more multicast forwarding entries can be created.

Parameter Name	Parameter Meaning
ForwardingMode	Indicates the multicast forwarding mode: MAC address-based forwarding mode IP address-based forwarding mode
ModId	Indicates the module ID.
McIndex	Indicates the multicast index.
DetailInfo	Indicates the detailed information: ALLOC HOLD

The number of multicast forwarding entries has reached the upper limit, or the resource application failed.

Run the display multicast forwarding-table command to check the Layer 3 forwarding table or run the display l2-multicast forwarding-table command to check Layer 2 multicast forwarding table. Determine whether the number of multicast entries exceeds the product specification. For the product specifications, log in to Huawei official website to download the product brochure or product feature list for channel (if your account is unauthorized, contact Huawei local office).
- If yes, go to step 2.
- If no, the resource application may have failed. Go to step 3.
Run the reset multicast forwarding-table [ group-address | source-address ] command to delete redundant Layer 3 multicast forwarding entries. Or run the reset igmp-snooping group vlan [ vlan-id ] group-address [ group-address ] command to delete redundant Layer 2 multicast forwarding entries. Then re-configure multicast services. If this log persists, go to step 3.
Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
