FR QoS commands
cir allow
Use cir allow to set the CIR ALLOW for an FR class.
Use undo cir allow to delete the CIR ALLOW setting of an FR class.
Syntax
cir allow [ inbound | outbound ] committed-information-rate
undo cir allow [ inbound | outbound ]
Default
The CIR ALLOW of an FR class is 56000 bps.
Views
FR class view
Predefined user roles
network-admin
Parameters
inbound: Sets the CIR ALLOW for incoming packets. The inbound CBS ALLOW takes effect only for FRTP.
outbound: Sets the CIR ALLOW for outgoing packets. The outbound CBS ALLOW takes effect only for FRTS.
committed-information-rate: Specifies the CIR ALLOW in bps.The value range for this argument is 1000 to 45000000.
Usage guidelines
The outbound CIR ALLOW must be greater than or equal to the CIR.
If you do not specify the inbound or outbound keyword, the set CIR ALLOW takes effect on both incoming and outgoing packets.
Examples
# Set the CIR ALLOW to 64000 bps for FR class test1.
<Sysname> system-view
[Sysname] fr class test1
[Sysname-fr-class-test1] cir allow 64000

Parameters
fr-class class-name: Specifies an FR class by its name, a case-sensitive string of 1 to 30 characters.
interface interface-type interface-number: Specifies an interface (main interface or subinterface) by its type and number. If you specify a main interface, the command displays the associations between the following elements:

Usage guidelines
If you do not specify any parameters, this command applies to all IP packets.
To add more IP-protocol-based DE rules to a DE rule list, repeat this command. A DE rule list can contain both interface-based DE rules and IP-protocol-based DE rules.
When the last DE rule in a DE rule list is deleted, the DE rule list is also deleted.
Examples
# Add a rule to DE rule list 1 that sets the DE bits of all IP packets to 1.

<Sysname> system-view
[Sysname] fr class test1
[Sysname-fr-class-test1] fragment size 128
fr-class
Use fr-class to associate an FR class with an FR interface or FR PVC.
Use undo fr-class to cancel the association.
Syntax
fr-class class-name
undo fr-class class-name
Default
An FR class is not associated with any FR interface or FR PVC.

Predefined user roles
network-admin
Parameters
class-name: Specifies an FR class by its name, a case-sensitive string of 1 to 30 characters. The FC class must already exist.
Usage guidelines
For an interface associated with an FR class, all PVCs on the interface inherit the FR QoS parameters in the FR class.
Examples
# Associate FR class test1 with an FR PVC with DLCI 200.
<Sysname> system-view
[Sysname] interface serial 2/1/1
[Sysname-Serial2/1/1] fr dlci 200
[Sysname-Serial2/1/1-fr-dlci-200] fr-class test1

traffic-shaping adaptation
Use traffic-shaping adaptation to enable FRTS adaptation for an FR class.
Use undo traffic-shaping adaptation to disable FRTS adaptation for an FR class.
Syntax
traffic-shaping adaptation { becn | interface-congestion number }
undo traffic-shaping adaptation { becn | interface-congestion }
Default
FRTS adaptation is disabled for an FR class.
Views
FR class view
Predefined user roles
network-admin
Parameters
becn: Adjusts the traffic rate in response to BECNs.
interface-congestion number: Adjusts the traffic rate in response to the number of packets in the output queue on the interface. The value range for the number argument is 1 to 40.
Usage guidelines
For BECN-based adaptation, the router reduces the transmission rates of all FRTS-enabled PVCs associated with the FR class when it receives packets with the BECN bit set. When the router does not receive packets with the BECN bit set within 125 milliseconds, it increases the transmission rates of those PVCs.
For interface congestion-based adaptation, the router reduces the transmission rates of all FRTS-enabled PVCs associated with the FR class when the number of packets in the output queue reaches the threshold. When the number of packets drops below the threshold, the router increases the transmission rates of those PVCs.
Examples
# Enable FRTS adaptation to adjust the traffic rate in response to BECNs.
<Sysname> system-view
[Sysname] fr class test1
[Sysname-fr-class-test1] traffic-shaping adaptation becn
Related commands
fr traffic-shaping
traffic-shaping adaptation percentage
Use traffic-shaping adaptation percentage to set the rate adjustment percentage for FRTS adaptation.
Use undo traffic-shaping adaptation percentage to restore the default.
Syntax
traffic-shaping adaptation percentage number
undo traffic-shaping adaptation percentage
Default
The rate adjustment percentage for FRTS adaptation is 25%.
Views
FR class view
Predefined user roles
network-admin
Parameters
number: Specifies the rate adjustment percentage, in the range of 1 to 30.
Usage guidelines
When rate adjustment is triggered, the router reduces or increases the traffic rate by the set percentage of the current rate. The adjusted rate must be between the CIR and the CIR ALLOW. For example, the current rate is 3000 bps, the rate adjustment percentage is 20%, and the CIR is 2500 bps. The rate is reduced to 2400 bps (3000 – 3000 x 20%). Because the adjusted rate cannot be lower than the CIR, the adjusted rate should be 2500 bps.
Examples
# Set the rate adjustment percentage to 20%.
<Sysname> system-view
[Sysname] fr class test1
[Sysname-fr-class-test1] traffic-shaping adaptation percentage 20
