QoS Configuration of car-port(distributing-mode)

Function Description

QoS refers to quality of service. The settings of different QoS parameters, such as service availability, throughput, time delay, jitter, and loss rate, provide users with high quality services. QoS processes the packets filtered by the ACL according to the requirements. The MA5680T/MA5683T/MA5608T can ensure high QoS for user services based on the traffic rule classification, measurement and scheduling policies.

Function

The car-port command is used to configure the port rate limitation by using a traffic profile. Operators prioritize user packets by CoS values based on service requirements. To implement committed access rate (CAR) policies on the packets with CoS values to avoid traffic burst, run this command.
The undo car-port command is used to delete the configuration of port rate limitation.

Format

In the ADSL mode, VDSL mode, SHDSL mode, OPF mode, and OPG mode:
car-port portid cos cos-value inbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name } outbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name }
undo car-port portid [ cos cos-value ]
In the GPON mode:
car-port portid gemport gemportid cos cos-value inbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name } outbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name }
undo car-port portid gemport gemportid [ cos cos-value ]
In the ETH OPG mode:
car-port portid vlan { vlanid [ to end-vlanid ] | vlan-list | unaware } inbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name } outbound { [ traffic-table index ] ip-traffic-table-index | traffic-table name ip-traffic-table-name }
undo car-port portid vlan { vlanid [ to end-vlanid ] | vlan-list | unaware }

Parameters

Parameter Description Value
portid Indicates the ID of the port on which the CAR policies are implemented. Please see Differences Between Shelves.
gemport gemportid GEM port number. GEM ports of each PON port are numbered in a centralized way. GEM ports 0-127 are reserved for the private use of OMCI and GEM ports 4000-4095 serve as channels for special use. Numeral type. Range: 128-3999.
cos cos-value Indicates the 802.1p priority in the specified packets. After setting this parameter, specify the inbound or outbound parameter to further bind the packets with CoS values to the traffic profile. Numeral type. Range: 0-7.
vlan vlanid Indicates the VLAN ID, which uniquely identifies a VLAN. You can specify this parameter to implement CAR policies for user-specific packets or service-specific packets on a port to achieve more intensive QoS control.
NOTE:
Only the SPUA, OPGE, SPUC board allows you to limit the rate of the packets in a specified VLAN on the port.
 Numeral type. Range: 1-4093.
to end-vlanid This parameter is used with vlanid to specify the VLAN range. Numeral type. Range: 1-4093.
end-vlanid must be larger than or equal to vlanid
vlan-list Indicates the VLAN list. To configure or cancel the VLAN attributes in batches, use this parameter. For example, VLAN list "2,4-6,10" indicates VLANs 2, 4, 5, 6, and 10. Character string type, a string of 1-256 characters.
unaware Indicates that VLAN is not specified. To not configure VLAN values during CAR port configurations, use this parameter. -
inbound
To implement rate limitation for the inbound direction of a port.
NOTE:
  • The inbound direction is from the user access side to the network side in the case of user port or cascade port.
  • The inbound direction is from the network side to the user access side in the case of network port.
 -
outbound
To implement rate limitation for the outbound direction of a port.
NOTE:
  • The outbound direction is from the network side to the user access side in the case of user port or cascade port
  • The outbound direction is from the user access side to the network side in the case of network port.
 -
traffic-table { index ip-traffic-table-index | name ip-traffic-table-name }
Indicates the traffic profile. You can specify this parameter either by profile index or by profile name to bind a traffic profile to the packets with the CoS value specified by cos cos-value:
  • index ip-traffic-table-index: Indicates the index of the traffic profile.
  • name ip-traffic-table-name: Indicates the name of the traffic profile.
You can run the traffic table ip command to create a traffic profile.		 indexip-traffic-table-index
Numeral type. Range: 0-1023.
name ip-traffic-table-name
Character string type, a string of 1-32 characters.
The 92 characters allowed by the system are as follows:
  • English letters: case sensitive
  • Numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9
  • ! # $ % & ' ( ) * + , - . / : ; < = > @ [ \ ] ^ _ ` { | } ~

Usage Guidelines

  • Run the config command to enter the global config mode, and then run the interface adsl command to enter the ADSL mode.
  • Run the config command to enter the global config mode, and then run the interface shl command to enter the SHDSL mode.
  • Run the config command to enter the global config mode, and then run the interface vdsl command to enter the VDSL mode.
  • Run the config command to enter the global config mode, and then run the interface opf command to enter the OPF mode.
  • Run the config command to enter the global config mode, and then run the interface opg command to enter the OPG mode.
  • Run the config command to enter the global config mode, and then run the interface eth command to enter the ETH mode.
  • Run the config command to enter the global config mode, and then run the interface gpon command to enter the GPON mode.
  • Before setting the rate limitation on the packet with a specified priority on the port, run the car-mode command to set the rate limitation to be based on port and priority, and then run the traffic table ip command to create the traffic profile to be referenced. When you need to limit the rate of the packets in a specified VLAN on the port, you do not need to set the rate limitation mode because such a case is irrelevant to the rate limitation mode.
  • The following table lists CAR specifications and granularities for CoS packets on different boards.
    NOTE:
    The value of a CAR specification indicates the number of rules that can be configured by running the car-port command.
    Board types Specifications for CAR Granularities for CAR
    SCUN/SCUH control board 5120 -
    Other control board 1024 -
    GPON board 1024 The rate is limited based on GEM port+CoS and all rates configured for each GEM port only occupies one specification.
    Other board It is limited by the specification of control board. The rate is limited based on port+CoS and all rates configured for each port only occupies one specification.

Example

To limit the rate of the packet with priority 5 on port 0/3/0 through traffic profile 5, do as follows:
huawei(config-if-gpon-0/3)#car-port
{ portid<U><0,7> }:0
{ gemport<K> }:gemport
{ gemportid<U><128,3999> }:128
{ cos-group-table<K>|cos-group<K>|cos<K> }:cos
{ cos-value<U><0,7> }:5
{ inbound<K> }:inbound
{ ip-traffic-table-index<U><0,1023>|traffic-table<K> }:5
{ outbound<K> }:outbound
{ ip-traffic-table-index<U><0,1023>|traffic-table<K> }:5

  Command:
          car-port 0 gemport 128 cos 5 inbound 5 outbound 5
To cancel rate limitation on the packets of GEM port 128 on GPON port 0/3/0, do as follows:
huawei(config-if-gpon-0/3)#undo car-port
{ portid<U><0,7> }:0
{ gemport<K> }:gemport
{ gemportid<U><128,3999> }:128
{ <cr>|cos-group<K>|cos<K> }:

  Command:
          undo car-port 0 gemport 128

System Response

  • The system does not display any message after the command is executed successfully.
