netstat -ib Obytes empty for alias on main interface

[Nicolas de Bari Embriz Garcia Rojas]

Here is the output with a better formatting:

http://pastebin.com/arrRsM78

What I would like to understand is why lo1 shows Obytes (incrementing)
while bce0 IP's don't

lo1 is a using NAT

also the sum of lo1 (not including the <Ling# main link) do not mach.

can some one please help me to better understand the output of netstat -ib .


regards.
