other end, so you decide to set the maximum transmission rate to 2.048 Mbps.
(You can calculate the B
sion rate: 2,048,000 bits - 1,500,000 bits = 548,000 bits.)
Because the Frame Relay network carries VoIP frames, you must fragment
large data frames to maintain QoS for the voice traffic. The size of the VoIP
frames is 207 bytes.
You would shape traffic on the Frame Relay PVC as follows:
ProCurve(config)# interface frame-relay 1.1
ProCurve(config-fr 1.1)# frame-relay bc 1500000
ProCurve(config-fr 1.1)# frame-relay be 548000
ProCurve(config-fr 1.1)# frame-relay fragment 210

Configuring QoS for Ethernet

The ProCurve Secure Router allows you to apply rate limiting and QoS to
Ethernet interfaces. These QoS mechanisms affect traffic passed through the
router to the LAN.

Overview

You can configure these QoS mechanisms on Ethernet interfaces:

rate limiting

outbound QoS policies
You must enable rate limiting in order to apply a QoS map to the Ethernet
interface.
Rate Limiting
Rate limiting helps maintain QoS when traffic transits across connections of
varying bandwidth. For example, an Ethernet interface may pass traffic at 100
Mbps to a device that can forward it at only 10 Mbps. The second device will
be forced to queue and finally drop many of these packets.
Rate limiting traffic passing through the Ethernet interfaces minimizes the
number of packets the router ultimately drops.
