DESCRIPTION
The IP Generic Packet Classifier (ipgpc) module provides packet classi‐
fication 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 relationship
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>
