Answer
The maximum emphemeral ports you can use on AIX is 64511.
tcp_ephemeral_high = 65535 Hard limit
tcp_ephemeral_low = 32768 Soft limit
tcp_ephemeral_low = 32768 Soft limit
The default ephemeral ports to be use is 32767.
To increase ephemeral ports to the maximum
# no -p -o tcp_ephemeral_low = 1024
The maximum range is between IPPORT_RESERVED(1024) - 65535, so you can assign the value respectively.
