IV67514: DOC : DOG THREADS CREATION CLARIFICATION APPLIES TO AIX 7100-03
A fix is available
Closed as program error.
Dosumentation for no option:ndogthreads states: A value of 0 sets it to default ie dog threads equal to the number of CPUs. Max value is 1024. This is not correct. The maximum number of dog threads is currently capped at 256 even if more cpus are available. -------------------------------------------------------- no -h ndogthreads Help for tunable ndogthreads: Purpose: Specifies the number of dog threads that are used during hashing. Values: Default: 0 Range: 0 - 1024 Type: Dynamic Unit: numeric Tuning: This option is valid only if dog threads are enabled for an interface. A value of 0 sets it to default ie dog threads equal to the number of CPUs. Max value is 1024. The minimum of tunable value and the number of cpus is taken as the number of dog threads during hashing.
The number of dog threads is determined at system initialization time as the smaller of "number of cpus" or 256. ndogthreads determines how many of these threads are active. The incoming packets are hashed across the number of active threads based on ipaddress and port (if available) unless they are raw. Raw packets are mapped to dog 0. Note that a single connection will utilize a single dog thread.
Help message of 'ndogthreads' no option is not clear on the number of dog threads created.
Modified the help message of 'ndogthreads' to state the purpose of this tunable and how the number of dog threads created is calculated.
