The FR class mapped to a DLCI takes effect only on the PVC identified by the DLCI.
An QoS-capable FR PVC selects an FR class in the following order:
•
The FR class mapped to the DLCI
•
The FR class mapped to the FR interface
To configure and create an FR class:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an FR class and
enter FR class view.
fr class
class-name
By default, no FR class is
created.
3.
Return to system view.
quit
N/A
4.
Map the
FR class to
an FR
interface or
DLCI.
(Method 1)
Map the FR
class to an
FR interface.
a.
Enter FR interface view:
interface
interface-type
interface-number
b.
Map the FR class to the FR
interface:
fr-class
class-name
Use either method or both
methods.
By default, no FR class is
mapped to any FR interface or
DLCI.
(Method 2)
Map the FR
class to an
DLCI.
c.
Enter FR interface view:
interface
interface-type
interface-number
d.
Enter FR PVC view:
fr dlci
dlci-number
e.
Map the FR class to the
DLCI:
fr-class
class-name
In FR class view, you can configure QoS parameters for QoS services such as FRTS, FR traffic
policing, FR congestion management, and FR queuing. For more information about the parameter
configurations, see the subsequent sections.
Configuring FRTS
Configuration restrictions and guidelines
•
FRTS applies to the outgoing FR packets. It is typically applied on DTE.
•
You can use the
cbs
,
ebs
, and
cir allow
commands to set both inbound and outbound
parameters for FR PVCs. However, only outbound parameters take effect for FRTS.
•
To ensure large-size packets can pass through, set CBS less than CIR ALLOW.
