This example shows how to display information about IP unicast traffic on interface Fast Ethernet 3/3:
Switch# show interface fastethernet 3/3 | begin L3
L3 in Switched: ucast: 0 pkt, 0 bytes - mcast: 12 pkt, 778 bytes mcast
L3 out Switched: ucast: 0 pkt, 0 bytes - mcast: 0 pkt, 0 bytes
4046399 packets input, 349370039 bytes, 0 no buffer
Received 3795255 broadcasts, 2 runts, 0 giants, 0 throttles
<...output truncated...>
Switch#
Note The IP unicast packet count is updated approximately every five seconds.
