pppstats - Print Point-to-Point Protocol (PPP) statistics
/usr/sbin/pppstats [-v] [-r] [-c] [-i secs] [unit#]
Displays additional statistics, such as the number of packets ignored (rejected by the VJ TCP header decompression code). Displays the overall packet compression rate. The rate value is between 0 and 1, with 0 meaning that the data is incompressible. Specifies an alternate display mode that shows packet compression statistics: the number of packets and bytes uncompressed (that is, before compression or after decompression), compressed, and incompressible (packets which did not shrink on compression and were transmitted uncompressed), and the recent compression rate. This rate reflects the recent performance of the compression code rather than the overall rate achieved since compression was enabled. Specifies the interval (in seconds) between printouts. The default is 5 seconds.
The pppstats command prints PPP-related statistics for the interface specified by unit#.
