/sbin/ifconfig

look at the TX (transmitted) and RX (recieved) values for each interface.
also you can see there ethernet collisions, packets who never got through,
packets that were dropped, how many packets are waiting on the queue to be
sent, and some other info which I didn't bother find out. As usual, "man"
is your friend.

Example for output:
eth0      Link encap:Ethernet  HWaddr [HIDDEN TO PROTECT THE INNOCENT;p]  
          inet addr:[MY IP]  Bcast:[MY BROADCAST ADDR] Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:8663972 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2164595 errors:0 dropped:0 overruns:0 carrier:0
          collisions:85444 txqueuelen:100 
          Interrupt:11 Base address:0x6040
