4 pppstats \- print PPP statistics
28 utility reports PPP-related statistics at regular intervals for the
29 specified PPP interface. If the interface is unspecified, it will
31 The display is split horizontally
32 into input and output sections containing columns of statistics
33 describing the properties and volume of packets received and
34 transmitted by the interface.
36 The options are as follows:
39 Display absolute values rather than deltas. With this option, all
40 reports show statistics for the time since the link was initiated.
41 Without this option, the second and subsequent reports show statistics
42 for the time since the last report.
47 times. If this option is not specified, the default repeat count is 1
50 option is not specified, otherwise infinity.
53 Display additional statistics summarizing the compression ratio
54 achieved by the packet compression algorithm in use.
57 Display additional statistics relating to the performance of the Van
58 Jacobson TCP header compression algorithm.
63 seconds between each display. If this option is not specified, the
64 default interval is 5 seconds.
67 Instead of the standard display, show statistics indicating the
68 performance of the packet compression algorithm in use.
70 The following fields are printed on the input side when the
75 The total number of bytes received by this interface.
78 The total number of packets received by this interface.
81 The number of header-compressed TCP packets received by this interface.
84 The number of header-uncompressed TCP packets received by this
85 interface. Not reported when the
90 The number of corrupted or bogus header-compressed TCP packets
91 received by this interface. Not reported when the
96 The number of VJ header-compressed TCP packets dropped on reception by
97 this interface because of preceding errors. Only reported when the
102 The total number of non-TCP packets received by this interface.
109 The compression ratio achieved for received packets by the
110 packet compression scheme in use, defined as the uncompressed size
111 divided by the compressed size.
112 Only reported when the
117 The total number of bytes received, after decompression of compressed
118 packets. Only reported when the
122 The following fields are printed on the output side:
125 The total number of bytes transmitted from this interface.
128 The total number of packets transmitted from this interface.
131 The number of TCP packets transmitted from this interface with
132 VJ-compressed TCP headers.
135 The number of TCP packets transmitted from this interface with
136 VJ-uncompressed TCP headers.
137 Not reported when the
142 The total number of non-TCP packets transmitted from this interface.
143 Not reported when the
148 The number of searches for the cached header entry for a VJ header
149 compressed TCP packet. Only reported when the
154 The number of failed searches for the cached header entry for a
155 VJ header compressed TCP packet. Only reported when the
160 The compression ratio achieved for transmitted packets by the
161 packet compression scheme in use, defined as the size
162 before compression divided by the compressed size.
163 Only reported when the
168 The total number of bytes to be transmitted, before packet compression
169 is applied. Only reported when the
177 instead displays the following fields, relating to the packet
178 compression algorithm currently in use. If packet compression is not
179 in use, these fields will all display zeroes. The fields displayed on
183 The number of bytes of compressed packets received.
186 The number of compressed packets received.
188 .B INCOMPRESSIBLE BYTE
189 The number of bytes of incompressible packets (that is, those which
190 were transmitted in uncompressed form) received.
192 .B INCOMPRESSIBLE PACK
193 The number of incompressible packets received.
196 The recent compression ratio for incoming packets, defined as the
197 uncompressed size divided by the compressed size (including both
198 compressible and incompressible packets).
200 The fields displayed on the output side are:
203 The number of bytes of compressed packets transmitted.
206 The number of compressed packets transmitted.
208 .B INCOMPRESSIBLE BYTE
209 The number of bytes of incompressible packets transmitted (that is,
210 those which were transmitted in uncompressed form).
212 .B INCOMPRESSIBLE PACK
213 The number of incompressible packets transmitted.
216 The recent compression ratio for outgoing packets.
