+.SH NAME
+pppstats \- report Point to Point Protocol statistics
+.SH SYNOPSIS
+.nf
+.ft B
+pppstats  [ \-i interval ] [ \-v ] [ unit ] [ system ] [ core ]
+.ft R
+.fi
+.SH DESCRIPTION
+.I Pppstats
+reports certain kernel statistics kept about Point to Point 
+Protocol traffic.
+.PP
+The options are as follows:
+.TP
+\-i
+Repeat the display indefinitely every
+.I interval
+seconds.
+If no
+.I interval
+is specified, the default is 5 seconds.
+.TP
+\-v
+Verbose display of extra fields of information.
+.TP
+unit
+is a single digit specifying the slip interface. The default unit is
+.I 0
+for interface
+.I ppp0.
+.TP
+system
+Extract the name list from the specified system instead of the default, /kernel.
+.TP
+core
+Extract values associated with the name list from the specified
+core instead of the default, /dev/kmem.
+.PP
+By default,
+.I pppstats
+displays the following information:
+.PP
+.TP
+in
+bytes received
+.TP
+out
+bytes sent
+.TP
+pack
+packets received or sent
+.TP
+comp
+compressed packets received or sent
+.TP
+uncomp
+uncompressed packets received or sent
+.TP
+err
+input or output errors
+.PP
+With the \-v option, the following information is also displayed:
+.TP
+toss
+inbound packets tossed because of error
+.TP
+search
+searches for connection state
+.TP
+miss
+times we could not find a connectoin state
+.SH EXAMPLES
+The command ``pppstats -i 5'' will print what the system is doing every five
+seconds.
