from netstat(1):

      -i      Show the state of interfaces which have been auto- 
configured (in-
              terfaces statically configured into a system but not  
located at
              boot-time are not shown).

              If the -a option is also present, multicast addresses  
currently
              in use are shown for each Ethernet interface and for  
each IP in-
              terface address.  Multicast addresses are shown on  
separate lines
              following the interface address with which they are  
associated.

              If the -f address_family option (with the -s option) is  
present,
              show per-interface statistics on all interfaces for the  
specified
              address_family.

You might also be interested in the -I flag for interface specific  
details.

      -s      Show per-protocol statistics.  If this option is  
repeated, coun-
              ters with a value of zero are suppressed.

man is your friend.. :)
