What's wrong with netstat?
netstat -i | -I interface [-abdnt] [-f address_family] [-M core]
[-N system]
Show the state of all network interfaces or a single interface
which have been auto-configured (interfaces statically configured
into a system, but not located at boot time are not shown). An
asterisk (``*'') after an interface name indicates that the
interface is ``down''. If -a is also present, multicast
addresses currently in use are shown for each Ethernet interface
and for each IP interface address. Multicast addresses are shown
on separate lines following the interface address with which they
are associated. If -b is also present, show the number of bytes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
in and out. If -d is also present, show the number of dropped
^^^^^^^^^^^
packets. If -t is also present, show the contents of watchdog
timers.
