HAL.IPv4FIB.ECMPTblFull

Description

The hardware Equal-Cost Multi-Path table has been exceeded and at least one set of IPv4 unicast ECMP routes could not be added to the hardware. When this occurs, a single, non-ECMP route will remain in the LPM table in hardware. This message will be logged at most 1 time per hour when new sets of IPv4 unicast ECMP routes trigger this condition.

Remedy

An associated debug-summary severity message "HAL.IPv4FIB.ECMPTblFullEnt" can be enabled to view per-occurrence details including the subnet and next hop IP address. In addition, "debug hal show ipv4fib" can be used to determine which IP unicast route entries were not added to hardware as ECMP routes. Any entry in this display without the "F" (Forwarded to hardware) flag is not currently programmed in hardware. The "M" Multipath flag indicates the route is ECMP. Even an entry in this display with the "F" (Forwarded to hardware) flag may not be currently programmed in hardware on all BD8800 I/O modules or SummitStack nodes. Use the "debug hal show ipv4fib slot N" on a module or node, and look for the "S" (Setup in hardware) flag and "M" Multipath flags.
