dscpmk

- Differentiated Services Code Point Marker

Description

The dscpmk marker is an action module that is executed as a result of classifying or metering packets. It sets a codepoint in the IP header as defined in RFC-2474: Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers.

Statistics

The dscpmk module exports the following statistics available through kstat:

Global statistics:

module: dscpmk                     instance: <action id>
  name: dscpmk stats               class <action name>
        crtime
        snaptime
        npackets                    <number of packets>
        epackets                    <number of packets in error>
        ipackets                    <number of packets not processed>
        dscp_unchanged              <number of packets with DSCP unchanged>
        dscp_changed                <number of packets with DSCP changed>

Also, for each DSCP the following is exported:
     module: dscpmk                         instance: <action id>        
     name: dscpmk_dscp0x<DSCP> value class:  <action name>
     dscp                                   <DSCP value>
     npackets                               <number of packets for this DSCP>

Notes

The IPQoS facility may be removed in a future release. Users are encouraged to migrate to dladm(1M), dlstat(1M), flowadm(1M), and flowstat(1M), which support similar bandwidth resource control features.
