ipqosconf(1M) System Administration Commands ipqosconf(1M)NAMEipqosconf - configure the IPQoS facility
SYNOPSIS
/usr/sbin/ipqosconf
/usr/sbin/ipqosconf -a conf_file [-vs]
/usr/sbin/ipqosconf -c
/usr/sbin/ipqosconf -f
/usr/sbin/ipqosconf -l
/usr/sbin/ipqosconf -L
DESCRIPTION
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 con‐
figuration every time that the machine reboots. To apply the configura‐
tion early in the boot phase, you can populate the
/etc/inet/ipqosinit.conf file, which is then read from the svc:/net‐
work/initial:default service.
OPTIONS
The following options are supported:
-a conf_file Apply the configuration in conf_file. If the conf_file
is −, ipqosconf reads from standard input.
-c Populate the boot file with the current configuration.
-f Flush the configuration.
-l List the current applied configuration.
-L List the current configuration in verbose mode.
In addition to the information that the -l option pro‐
vides, the -L option provides filters and classes con‐
figured 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
-s Log messages to syslog during an -a operation.
-v 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 console.
CONFIGURATION FILE
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 con‐
figured. A configuration block always has the following structure:
action {
name action_name
module module_name
params_clause | ""
cf_clauses
}
action_name ::= string
module_name ::= ipgpc | dlcosmk | dscpmk | flowacct | tswtclmt |
tokenmt
params_clause ::= params {
parameters
params_stats | ""
}
parameters ::= prm_name_value parameters | ""
prm_name_value ::= param_name param_value
Modules
The param_name and the types of param_value are specific to a given
module.
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_stats | ""
}
class_name ::= string
next_action_name ::= string
class_stats ::= enable_stats boolean
boolean ::= TRUE | FALSE
filter_clause ::= filter {
name filter_name
class class_name
parameters
}
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.
The set of types that are used for parameters of the different modules
are:
action ::= string
protocol ::= 1..255
port ::= 1..65535

Types
action A string of characters with a matching action defini‐
tion. 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 pro‐
cessing. drop causes the packet that is passed to it
to be dropped.
address A machine name or address recognized by getipnodeby‐
name(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 speci‐
fied and ip_version has not been defined, the query is
done using the AI_DEFAULT flag to getipnodeby‐
name()(..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.
enum Either one of the supported values or comma delimited
list of support values, enclosed in curly braces.
ifname A non-NULL, existing interface name recognized by the
SIOGLIFINDEX socket ioctl.
integer_array 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.
map_index 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 num‐
ber of entries in the associated maps. The index
starts at 0.
port Either a service name recognized by getservby‐
name(3SOCKET) or an integer 1-65535.
protocol Either a protocol name recognized by getprotoby‐
name(3SOCKET) or an integer 1-255.
string A character string. Enclose string in quotes. string
cannot span multiple lines.
user Either a valid user ID or username for the system that
is being configured.
Parameters
The configuration file can contain the following parameters
color_aware A value of TRUE or FALSE, indicating whether or
not the configured action takes account of the
previous packet coloring when classifying.
color_map 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.
committed_burst The committed burst size in bits.
committed_rate The committed rate in bits per second.
cos The value used to determine the underlying
driver level priority applied to the packet
which is defined in 802.1D.
daddr The destination address of the datagram.
direction 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 traf‐
fic entering the system), and FWD_OUT (forwarded
traffic exiting the system).
dport The destination port of the datagram.
dscp_detailed_stats A value of TRUE or FALSE that determines whether
detailed statistics are switched on for this
dscp action.
Specify TRUE to switch on or FALSE to switch
off.
dscp_map 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.
dsfield The DS field of the IP datagram header. This is
an 8-bit value, with each bit position corre‐
sponding 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 spec‐
ify the dsfield_mask parameter.
dsfield_mask 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 corre‐
sponding with the same one in the dsfield param‐
eter.
global_stats A value of TRUE or FALSE to enable or disable
the statistic collection for this action.
green_action_name The action to be executed for packets that are
deemed to be green.
if_name The name of an interface recognized by the
SIOGLIFINDEX ioctl. This parameter is of type
ifname.
ip_version 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 hostname.
max_limit The maximum number of flow entries present at
one time in the flowacct actions in the memory
resident table.
next_action 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.
peak_burst The peak burst size, for a two rate meter, or
excess burst size, for a single rate meter, in
bits.
peak_rate The peak rate in bits per second.
precedence 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 param‐
eter should be used because the order of the
filters in a configuration file has no influence
on their relative precedence.
priority 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
priority.
projid The project ID of the process sending the data.
This value is always -1 for received traffic.
protocol The Upper Layer Protocol against which this
entry is matched.
red_action_name The action to be executed for packets that are
determined to be red.
saddr The source address of the datagram.
sport The source port of the datagram.
timeout The timeout in milliseconds after which flows
are written to the accounting file.
timer The period in milliseconds at which timed-out
flows are checked for.
user The user ID or username of the process sending
the data. This value is always -1 for received
traffic.
window The window size in ms.
yellow_action_name The action to be executed for packets that are
determined to be yellow.
SECURITY
None.
EXAMPLES
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
params{
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
params{
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
}
}

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 dur‐
ing an application then all error and change notificationmessages are
sent to the console as well as their default destination.
