IPQOSCONF(8) Maintenance Commands and Procedures IPQOSCONF(8)

ipqosconf - configure the IPQoS facility

/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

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.

-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 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

-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.

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.

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.

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 | ""


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


                     tokenmt

                        parameters


                        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 module.

                         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:

next_action      action
timer            uint32

max_limit        uint32

action

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.

address

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.

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 number of entries in the associated maps. The index starts at 0.

port

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

protocol

Either a protocol name recognized by getprotobyname(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.

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 traffic 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 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.

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 corresponding with the same one in the dsfield parameter.

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 ipv4 addresses 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 parameter 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.

None.

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


        }
}

/etc/inet/ipqosinit.conf

Contains the IPQoS configuration loaded at boot time. If this file exists, it is read from the network/initial:default service.

/etc/inet/ipqosconf.1.sample

Sample configuration file for an application server

/etc/inet/ipqosconf.2.sample

Sample configuration file that meters the traffic for a specified application

/etc/inet/ipqosconf.3.sample

Sample configuration file that marks the ethernet headers of web traffic with a given user priority

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 notification messages are sent to the console as well as their default destination.
