8. Return to the QoS Map window. The Apply a QoS-policy to an Interface
window lists the name of all logical interfaces active on the router. The
display includes an Ethernet interface only if you have configured rate
limiting for it. Select the map name from the pull-down menu next to the
name of the interface that should mark packets.

Configuring Frame Relay Fragmentation and Rate
Limiting
These instructions assume that you have already configured the Frame Relay
interface and PVCs. (See "Configure Frame Relay as the Data Link Layer
Protocol" on page 14-52 of the Basic Management and Configuration Guide.)
Follow these steps to configure fragmentation and rate limiting for a PVC:
1. Access the Frame Relay subinterface for the PVC for which you want to
limit the rate.
a. Click IP Interfaces under Router/Bridge in the left navigation bar.
Select the Frame Relay subinterface.
b. If this interface does not have an IP address, then you must instead
select Physical Interfaces under System. Then choose the Frame
Relay interface associated with the PVC. You can then select the
subinterface from the Configured Permanent Virtual Circuits win-
dow.
c. The Configuration window for the Frame Relay subinterface dis-
plays.
2. The router fragments any packet larger than the fragmentation threshold.
Set the threshold in bytes in the Fragment field.
If this Frame Relay PVC will carry VoIP traffic, take care to set the fragmen-
tation threshold above the size of VoIP packets.
3. The committed burst rate determines the rate at which the Frame Relay
interface can forward traffic when the network is congested. You should
set the committed burst rate to equal the committed information rate
(CIR) that you have negotiated with your service provider. Enter the rate
in bps in the BC field.
4. The excessive burst rate determines the maximum rate at which the
Frame Relay subinterface can ever forward traffic. Some service provid-
ers allow you to burst up to the interface's transmission rate. Others
specify an excessive information rate (EIR). Consult your service level
agreement (SLA). The value you enter in the BE field is the rate over the
