HAL.IPv4Mc.GrpTblFull

Description

The IPv4 multicast group table has been exceeded and at least one multicast forwarding entry was not added in hardware. Any (S,G) multicast streams without an associated hardware forwarding entry will be slowpath forwarded. This message will be logged at most 1 time per hour while new (S,G) forwarding entries trigger this condition.

Remedy

An associated debug-summary level message "HAL.IPv4Mc.GrpTblFullEnt" can be enabled to view per-occurrence details including (S,G) and vlan information. In addition, "debug hal show ipv4mc" can be used to determine which (S,G) forwarding entries were not added to hardware. Any entry in this display with "IPMC -1" is not currently programmed in hardware.
