.SH DESCRIPTION
\fBiftop\fP listens to network traffic on a named \fIinterface\fP, or on the
\fB-m\fP \fIlimit\fP
Set the upper limit for the bandwidth scale. Specified as a number with a 'K', 'M' or 'G' suffix.
.TP
+\fB-u\fP \fIbits\fP|\fIbytes\fP|\fIpackets\fP
+Display bandwidth rates in the given unit (per second).
+.TP
\fB-B\fP
-Display bandwidth rates in bytes/sec rather than bits/sec.
+Synonym for \fB-u\fP \fIbits\fP.
.TP
\fB-i\fP \fIinterface\fP
Listen to packets on \fIinterface\fP.
\fBhide-destination:\fP \fI(yes|no)\fP
Hides destination host names.
.TP
+\fBbandwidth-unit:\fP \fI(bits|bytes|packets)\fP
+Use the specified unit for bandwidth display. The default is bits.
+.TP
\fBuse-bytes:\fP \fI(yes|no)\fP
-Use bytes for bandwidth display, rather than bits.
+\fBuse-bytes: yes\fP is a synonym of \fBbandwidth-unit: packets\fP.
.TP
\fBsort:\fP \fI(2s|10s|40s|source|destination)\fP
Sets which column is used to sort the display.
