18 !!DESCRIPTION
19
20
21 The __pppstats__ utility reports PPP-related statistics
22 at regular intervals for the specified PPP interface. If the
23 interface is unspecified, it will default to ppp0. The
24 display is split horizontally into input and output sections
25 containing columns of statistics describing the properties
26 and volume of packets received and transmitted by the
27 interface.
28
29
30 The options are as follows:
31
32
33 __-a__
34
35
36 Display absolute values rather than deltas. With this
37 option, all reports show statistics for the time since the
38 link was initiated. Without this option, the second and
39 subsequent reports show statistics for the time since the
40 last report.
41
42
43 __-c__ ''count''
44
45
46 Repeat the display ''count'' times. If this option is not
47 specified, the default repeat count is 1 if the __-w__
48 option is not specified, otherwise infinity.
49
50
51 __-r__
52
53
54 Display additional statistics summarizing the compression
55 ratio achieved by the packet compression algorithm in
56 use.
57
58
59 __-v__
60
61
62 Display additional statistics relating to the performance of
63 the Van Jacobson TCP header compression
64 algorithm.
65
66
67 __-w__ ''wait''
68
69
70 Pause ''wait'' seconds between each display. If this
71 option is not specified, the default interval is 5
72 seconds.
73
74
75 __-z__
76
77
78 Instead of the standard display, show statistics indicating
79 the performance of the packet compression algorithm in
80 use.
81
82
83 The following fields are printed on the input side when the
84 __-z__ option is not used:

130 specified.
131
132
133 __NON-VJ__
134
135

137 interface. Only reported when the __-v__ option is
138 specified.
139
140
141 __RATIO__
142
143
144 The compression ratio achieved for received packets by the
145 packet compression scheme in use, defined as the

147 reported when the __-r__ option is
148 specified.
149
150
151 __UBYTE__
