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.
• FRTS does not support fast forwarding. The configured FRTS takes effect after fast forwarding is
disabled. For more information about fast forwarding, see Layer 3—IP Services Configuration
Guide.
• 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.
