NAME

       ipgpc - IP Generic Packet Classifier

DESCRIPTION

       The  IP	Generic Packet Classifier (ipgpc) module provides packet classification at the Solaris IP layer. ipgpc is an implementation of the
       Multi-Field (MF) classifier as described in RFC2475: An Architecture for Differentiated Services.

       The classifier is configured, at startup or dynamically, using a set of "filters." Filters describe  selectors  that  are  matched  against
       input  packets  that  are processed by the classifier. Some selectors feature exact matching data points, while others utilize non-exact or
       wildcard data points.

       Each filter is associated with a class describing the next actions to process a packet. There is a many-to-one (M-to-1)	mapping  relation-
       ship  between  filters and a class. Additionally, each class is aware of which filters are associated with it. A class is configured with a
       class name and a next action.

       Unlike traditional classifiers used in edge routers, ipgpc is designed for a host or server device. A host-based classifier provides access
       to more resources and data than edge routers. User, project, and interface information are available at the host.

STATISTICS

       The ipgpc module exports global and per-class statistics (available through kstat:)

       Global statistics:

       module: ipgpc			       instance:<action id>
       name:   ipgpc global stats	       class: <action name>
	       crtime
	       snaptime
	       nbytes			       <number of classified bytes>
	       nclasses 		       <number of classes>
	       nfilters 		       <number of filters>
	       npackets 		       <number of classified packets>
	       epackets 		       <number of packets in error>

       Per-class statistics:

       module: ipgpc			       instance:<action id>
       name:   <class name>		       class: <action name>
	       crtime
	       snaptime
	       last match		       <time of last match>
	       nbytes			       <number of classified bytes>
	       npackets 		       <number of classified packets>
