Protocol Statistics

The netstat –s command displays statistics for the following protocols:
ICMP, UDP, TCP, IP, TMux, LAT, and DDP. The LAT statistics display
only if the correct lat_key value is set; TMux statistics display only if the
tmux_enable parameter is set to Y; DDP statistics display only if the
correct option_key value is set. A truncated view looks something like
this:
