.SH STATE TOP
Using the \fB\-t\fP option \fBipfstat\fP will enter the state top mode. In
this mode the state table is displayed similar to the way \fBtop\fP displays
the process table. The \fB\-C\fP, \fB\-D\fP, \fB\-P\fP, \fB\-S\fP and\fB\-T\fP
commandline options can be used to restrict the state entries that will be
shown and to specify the frequency of display updates.
.PP
In state top mode, the following keys can be used to influence the displayed
information. \fBl\fP can be used to redraw the screen. \fBq\fP is used to
quit the program. \fBs\fP can be used to change the sorting criterion and
\fBr\fP can be used to reverse the sorting criterion.
.PP
States can be sorted by protocol number, by number of IP packets, by number
of bytes and by time-to-live of the state entry. The default is to sort by
the number of bytes. States are sorted in descending order, but you can use
the \fBr\fP key to sort them in ascending order.
.SH STATE TOP LIMITATIONS
It is currently not possible to interactively change the source, destination
and protocol filters or the refreh frequency. This must be done from the
command line.
.PP
The screen must have at least 80 columns. This is however not checked.
