R3303-HP HSR6800 Routers ACL and QoS Configuration Guide

131
• The FR class mapped to an FR interface takes effect on all PVCs on the interface.
• 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:

8. 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.
Configuration procedure
To configure FRTS:
