Date, time, and how long ago the interface went from down to up. The format<br />

is Last flapped: year-month-day hour:minute:second timezone (hour:minute:second<br />

ago). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).<br />

Time when the statistics for the interface were last set to zero.<br />

Number and rate of bytes and packets received and transmitted on the physical<br />

interface.<br />

• Input bytes, Output bytes—Number of bytes received and transmitted on the<br />

interface.<br />

• Input packets, Output packets—Number of packets received and transmitted<br />

on the interface.<br />
