21 .SH DESCRIPTION
22 .LP
23 The \fBipfstat\fR command is part of a suite of commands associated with the
24 Solaris IP Filter feature. See \fBipfilter\fR(5).
25 .sp
26 .LP
27 The \fBipfstat\fR command examines \fB/dev/kmem\fR using the symbols
28 \fB_fr_flags\fR, \fB_frstats\fR, \fB_filterin\fR, and \fB_filterout\fR. To run
29 and work, it needs to be able to read both \fB/dev/kmem\fR and the kernel
30 itself.
31 .sp
32 .LP
33 The default behavior of \fBipfstat\fR is to retrieve and display the statistics
34 which have been accumulated over time as the kernel has put packets through the
35 filter.
36 .sp
37 .LP
38 The role of \fBipfstat\fR is to display current kernel statistics gathered as a
39 result of applying the filters in place (if any) to packets going in and out of
40 the kernel. This is the default operation when no command line parameters are
41 present. When supplied with either \fB-i\fR or \fB-o\fR, \fBipfstat\fR will
42 retrieve and display the appropriate list of filter rules currently installed
43 and in use by the kernel.
44 .sp
45 .LP
46 \fBipfstat\fR uses kernel device files to obtain information. The default
47 permissions of these files require \fBipfstat\fR to be run as root for all
48 operations.
49 .sp
50 .LP
51 The \fBipfstat\fR command supports the \fBkstat\fR(3KSTAT) kernel facility.
52 Because of this support, as an alternative to \fBipfstat\fR, you can use
53 \fBkstat\fR(8). For example:
54 .sp
55 .LP
56 # kstat \(hym ipf
57 .sp
58 .LP
59 Using the \fBipfstat\fR \fB-t\fR option causes \fBipfstat\fR to enter the state
60 top mode. In this mode the state table is displayed similarly to the way the
61 Unix \fBtop\fR utility displays the process table. The \fB-C\fR, \fB-D\fR,
62 \fB-P\fR, \fB-S\fR and \fB-T\fR command line options can be used to restrict
63 the state entries that will be shown and to specify the frequency of display
64 updates.
65 .sp
66 .LP
67 In state top mode, use the following keys to influence the displayed
68 information:
69 .sp

97 .ne 2

99 \fB\fBs\fR\fR

102 Switch between different sorting criteria.
103 .RE
105 .sp
106 .ne 2

108 \fB\fBr\fR\fR
109 .ad
110 .RS 5n
111 Reverse the sorting criteria.
112 .RE
114 .sp
115 .LP
116 States can be sorted by protocol number, by number of IP packets, by number of
117 bytes, and by time-to-live of the state entry. The default is to sort by the
118 number of bytes. States are sorted in descending order, but you can use the
119 \fBr\fR key to sort them in ascending order.
120 .sp
121 .LP
122 It is not possible to interactively change the source, destination, and
123 protocol filters or the refresh frequency. This must be done from the command
124 line.
125 .sp
126 .LP
127 The screen must have at least 80 columns for correct display. However,
128 \fBipfstat\fR does not check the screen width.
129 .sp
130 .LP
131 Only the first \fIX\fR-5 entries that match the sort and filter criteria are
132 displayed (where \fIX\fR is the number of rows on the display). There is no way
133 to see additional entries.
134 .SH OPTIONS

195 \fIipaddress\fR[,\fIport\fR]. The \fIipaddress\fR and \fIport\fR should be
196 either numerical or the string \fBany\fR (specifying any IP address and any
