SLSTATS(8)		OpenBSD System Manager's Manual		    SLSTATS(8)

NAME
     slstats - report slip statistics

SYNOPSIS
     slstats [-v] [-i interval] [interface]

DESCRIPTION
     The slstats utility reports slip-related statistics for the slN
     interface.	 If the interface is unspecified, it defaults to sl0.  These
     statistics are displayed at regular intervals.

     The display is split horizontally into input and output sections
     containing columns of statistics describing the properties and volume of
     packets received and transmitted by the specified interface.

     The first report will consist of a snapshot of the interface's present
     statistics.  All further output will describe activity between report
     intervals.

     The options are as follows:

     -i interval
	     Specifies the interval between reports.  The default interval is
	     5 seconds.

     -v	     Display additional statistics demonstrating the efficacy of VJ
	     header compression and providing more explicit information on
	     failure distribution.

     The following fields are printed on the input side:

     IN	     The total number of bytes received by this interface.

     PACK    The total number of packets received by this interface.

     COMP    The number of compressed TCP packets received by this interface.

     UNCOMP  The number of uncompressed TCP packets received by this
	     interface.

     ERR     The number of packets received by this interface of unknown type.

     TOSS    The number of packets dropped on reception by this interface.
	     Only reported when the -v option is specified.

     IP	     The total number of non-TCP packets received by this interface.
	     Only reported when the -v option is specified.

     The following fields are printed on the output side:

     OUT     The total number of bytes transmitted from this interface.

     PACK    The total number of packets transmitted from this interface.

     COMP    The number of TCP packets compressed and then transmitted from
	     this interface.

     UNCOMP  The number of uncompressed TCP packets transmitted from this
	     interface.

     IP	     The total number of non-TCP packets transmitted from this
	     interface.

     SEARCH  The number of searches for the cached header entry for a
	     compressed packet.	 Only reported when the -v option is
	     specified.

     MISS    The number of failed searches for the cached header entry for a
	     compressed packet.	 Only reported when the -v option is
	     specified.
