ipqosconf - configure the IPQoS facility



/usr/sbin/ipqosconf -a conf_file [-vs]

/usr/sbin/ipqosconf -c

/usr/sbin/ipqosconf -f

/usr/sbin/ipqosconf -l

/usr/sbin/ipqosconf -L


The ipqosconf utility configures the Quality of Service facility of the
Internet Protocol (IP). Only superusers can use this command.

Without arguments, ipqosconf displays the actual IPQoS configuration.

Configuration is not preserved across reboot. You must apply the
configuration every time that the machine reboots. To apply the
configuration early in the boot phase, you can populate the
/etc/inet/ipqosinit.conf file, which is then read from the
svc:/network/initial:default service.


The following options are supported:

-a conf_file
Apply the configuration in conf_file. If the conf_file is
-, ipqosconf reads from standard input.

Populate the boot file with the current configuration.

Flush the configuration.

List the current applied configuration.

List the current configuration in verbose mode.

In addition to the information that the -l option
provides, the -L option provides filters and classes
configured through other means than the iqposconf
command. This option also provides the full set of
filters that were created by ipqosconf by representing a
multi-homed host in a configuration file

Log messages to syslog during an -a operation.

Toggle verbose mode during an -a operation.

The -v option causes all messages to go to the console in
addition to their normal destination. Messages intended
to go to syslog, because the -s flag is set or because it
is a log message, still go to syslog as well as the


The configuration file is composed of a format version and a succession
of configuration (action) blocks. There are different configuration
blocks for each type of action that is being configured.

Format Version

The first line of the configuration file specifies the format version
contained in the configuration file.

The following entry specifies the format version:

fmt_version x.x

where x.x is the format version. 1.0 is the only supported version.

Configuration Blocks

Following the format version, are a succession of configuration (action)
blocks that are different for each type of action being configured. A
configuration block always has the following structure:

action {
name action_name
module module_name
params_clause | ""

action_name ::= string
module_name ::= ipgpc | dlcosmk | dscpmk | flowacct | tswtclmt |

params_clause ::= params {
params_stats | ""

parameters ::= prm_name_value parameters | ""

prm_name_value ::= param_name param_value


The param_name and the types of param_value are specific to a given

params_stats ::= global_stats boolean

cf_clauses ::= class_clause cf_clauses |
filter_clause cf_clauses | ""

class_clause ::= class {
name class_name
next_action next_action_name

class_name ::= string
next_action_name ::= string
class_stats ::= enable_stats boolean
boolean ::= TRUE | FALSE

filter_clause ::= filter {
name filter_name
class class_name

filter_name ::= string

There must be exactly one configuration block belonging to module ipgpc.
The action must be named ipgpc.classify. All other actions should be
reachable from ipgpc by way of parameters of type action or the
next_action of a class.

A string of characters with a matching action
definition. The character string can be up to twenty
three characters in length. To allow for spaces the
string needs to be enclosed in quotes and cannot span
lines. Two special actions are pre-defined and can not
have an explicit action definition. The two pre-defined
actions are continue and drop. continue causes the
packet that is passed to it to continue normal
processing. drop causes the packet that is passed to it
to be dropped.

A machine name or address recognized by
getipnodebyname(3SOCKET). If a machine name is
specified, and ip_version has been defined, the query is
done using that address family. If a machine name is not
specified and ip_version has not been defined, the query
is done using the AI_DEFAULT flag to
getipnodebyname()(..AF_INET6..). CIDR address masks
following an IP address are allowed. Specify the CIDR
address masks as 1-32 (for v4) or 1-128 (for v6). CIDR
addresses are disallowed for node names.

Either one of the supported values or comma delimited
list of support values, enclosed in curly braces.

A non-NULL, existing interface name recognized by the
SIOGLIFINDEX socket ioctl.

A comma delimited set of range/value pairs, enclosed in
curly braces.

Specify range in the format x-y, where x and y are
integers that denote the range of array indexes to which
the value applies. The minimum value for both x and y
is 0. The maximum value for x is particular to the
parameter. Any array indexes not referred to in the set
of ranges are left at their previous value.

A non-negative integer used as an index into any maps
associated with a parameter of this type.

The maximum value of this type is dictated by the number
of entries in the associated maps. The index starts at

Either a service name recognized by
getservbyname(3SOCKET) or an integer 1-65535.

Either a protocol name recognized by
getprotobyname(3SOCKET) or an integer 1-255.

A character string. Enclose string in quotes. string
cannot span multiple lines.

Either a valid user ID or username for the system that
is being configured.


The configuration file can contain the following parameters

A value of TRUE or FALSE, indicating whether or
not the configured action takes account of the
previous packet coloring when classifying.

An integer array that defines which values of the
dscp field correspond with which colors for when
the color_aware parameter is set to TRUE.

The committed burst size in bits.

The committed rate in bits per second.

The value used to determine the underlying driver
level priority applied to the packet which is
defined in 802.1D.

The destination address of the datagram.

The value used to build a filter matching only
part of the traffic.

This parameter is of type enum with valid values
of LOCAL_IN (local bound traffic), LOCAL_OUT
(local sourced traffic), FWD_IN (forwarded traffic
entering the system), and FWD_OUT (forwarded
traffic exiting the system).

The destination port of the datagram.

A value of TRUE or FALSE that determines whether
detailed statistics are switched on for this dscp

Specify TRUE to switch on or FALSE to switch off.

The integer_array that supplies the values that IP
packets with a given dscp value have their dscp
re-marked with.

The existing value is used to index into the array
where the new value is taken from. The array is of
size 64, meaning valid indexes are 0-63 and valid
values are also 0-63.

The DS field of the IP datagram header. This is an
8-bit value, with each bit position corresponding
with the same one in the header; this enables
matches to be done on the CU bits. If you specify
this parameter, you must also specify the
dsfield_mask parameter.

The mask applied to the dsfield parameter to
determine the bits against which to match. This is
an 8-bit value, with each bit position
corresponding with the same one in the dsfield

A value of TRUE or FALSE to enable or disable the
statistic collection for this action.

The action to be executed for packets that are
deemed to be green.

The name of an interface recognized by the
SIOGLIFINDEX ioctl. This parameter is of type

This parameter is of type enum and has valid
values of V4 and V6.

If it is set to V4 only then only ipv4addresses
are requested for a specified hostname. If it is
set to V6, only ipv6 addresses are returned if
there are any, otherwise v4 mapped v6 addresses
are returned. If both V4 and V6 are specified, or
if ip_version is not specified, then both ipv4 and
ipv6 addresses are requested for a specified

The maximum number of flow entries present at one
time in the flowacct actions in the memory
resident table.

The action to be executed when the current action
is complete.

This value can be either the name of an action
defined in the configuration file, or one of the
two special action types: drop and continue.

The peak burst size, for a two rate meter, or
excess burst size, for a single rate meter, in

The peak rate in bits per second.

An integer that is used to order filters. If there
are two matching filters that have the same
priority value, the one with the lower precedence
value is the one matched. This parameter should be
used because the order of the filters in a
configuration file has no influence on their
relative precedence.

An integer that represents the relative priority
of a filter. If there are two matching filters,
the one with the higher priority value is the one
matched. Multiple filters can have the same

The project ID of the process sending the data.
This value is always -1 for received traffic.

The Upper Layer Protocol against which this entry
is matched.

The action to be executed for packets that are
determined to be red.

The source address of the datagram.

The source port of the datagram.

The timeout in milliseconds after which flows are
written to the accounting file.

The period in milliseconds at which timed-out
flows are checked for.

The user ID or username of the process sending the
data. This value is always -1 for received

The window size in ms.

The action to be executed for packets that are
determined to be yellow.




Example 1: Sending All Traffic From eng to the AF 1 Class of Service

This example sends all traffic from eng to the AF 1 class of service. It
is documented in four separate steps:

The following step creates a tokenmt action with three outcomes:

#meter for class 1.
action {
name AF_CL1
module tokenmt
committed_rate 64
committed_burst 75
peak_burst 150
global_stats TRUE
red_action_name drop
yellow_action_name markAF12
green_action_name markAF11

The following step creates two dscpmk actions:

#class 1, low drop precedence.
action {
name markAF11
module dscpmk
dscp_map {0-63:28}
dscp_detailed_stats TRUE
global_stats TRUE
next_action acct1
#class 1, medium drop precedence.
action {
name markAF12
module dscpmk
params {
dscp_map {0-63:30}
dscp_detailed_stats TRUE
global_stats TRUE
next_action acct1

The following step creates an accounting action:

#billing for transmitted class 1 traffic.
action {
name acct1
module flowacct
params {
timer 10
timeout 30
global_stats TRUE
max_limit 1024
next_action continue

The following step creates an ipgpc action:

#traffic from eng sent, traffic from ebay dropped.
action {
name ipgpc.classify
module ipgpc
class {
name from_eng
enable_stats TRUE
next_action AF_CL1
class {
name from_ebay
enable_stats TRUE
next_action drop

filter {
name from_eng
saddr eng-subnet
class from_eng
filter {
name from_ebay
saddr ebay-subnet
class from_ebay

ipqosconf sends messages to syslog of facility user, severity notice when
any changes are made to the IPQoS configuration.

Errors that occur during an ipqosconf operation send an error message to
the console by default. For the application of a new configuration if the
-s option is set then these messages are sent to syslog as facility user,
severity error instead. If the -v option is present during an application
then all error and change notificationmessages are sent to the console as
well as their default destination.
