Hi,

These values are variable:
 5 minute input rate 180000 bits/sec, 121 packets/sec
 5 minute output rate 1237000 bits/sec, 148 packets/sec

These values are only increasing unless a "clear counters" is issued:
    1807485647 packets input, 4267040170 bytes
    0 input packets with dribble condition detected
    2039691484 packets output, 2256843793 bytes, 0 underruns
