Configuring Rate Limiting for Frame Relay

7-50
You would complete the following configurations:
1. Create a QoS map entry for lowering the precedence for traffic with IP
precedence 5:
ProCurve(config)# qos map InternetConnection 10
ProCurve(config-qos-map)# match precedence 5
ProCurve(config-qos-map)# set precedence 3
2. Configure an ACL to select SIP signaling traffic, which travels to TCP and
UDP port 5060:
ProCurve(config)# ip access-list extended VoiceSignaling
ProCurve(config-ext-nacl)# permit tcp any any eq 5060
ProCurve(config-ext-nacl)# permit udp any any eq 5060
3. Configure another entry in the QoS map to mark traffic in the VoiceSig-
naling ACL for the AF31 PHB:
ProCurve(config)# qos map InternetConnection 11
ProCurve(config-qos-map)# match list VoiceSignaling
ProCurve(config-qos-map)# set dscp 26
4. Assign the QoS map to the PPP interface:
ProCurve(config) int ppp 1
ProCurve(config-ppp 1)# qos-policy out InternetConnection
If so desired, you could first configure more entries for the map to place
other traffic in low-latency queues or CBWFQ classes.
Configuring Rate Limiting for Frame
Relay

Overview

Rate limiting helps to maintain QoS on a Frame Relay connection and to
minimize the number of packets dropped during congestion.

Rate Limiting

The permanent virtual circuits (PVCs) established on a Frame Relay connec-
tion must share the bandwidth available to the carrier line. (For information
on how to increase this bandwidth by aggregating several carrier lines, see
Chapter 2: Increasing Bandwidth.) You can configure rate limiting to pre-
serve QoS on each PVC.
