At least 1 Permanent MAC FDB entry could not be added globally because the hardware table is full. The hardware table is organized as a hash table so it is possible that there is still room for other MAC FDB entries that hash to different hash bucket locations. This message will be logged at most 1 time per hour per slot while new FDB forwarding entries trigger this condition.
An associated debug-summary level message "HAL.FDB.L2GlobTblFullEnt" can be enabled to view per-occurrence details including MAC address and vlan information. In addition, "debug hal show fdb" can be used to determine which FDB entries were not added to hardware.
Warning
Permanent FDB entry not added. Hardware Table full.
