Configuring Frame Relay Rate Limiting - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

Setting Up Quality of Service
Example: Configuring QoS for VoIP
Then configure the QoS map entry. It should have the same name as, but a
different number than, the low-latency queue. For example:
ProCurve(config-ext-nacl)# qos map VoiceMap 21
Match the map to the ACL and set the DiffServ value:
ProCurve(config-qos-map)# match list VoiceSignaling
ProCurve(config-qos-map)# set dscp 26
Finally, apply the entire QoS map to the Frame Relay interface:
ProCurve(config)# interface frame-relay 1
ProCurve(config-fr 1)# qos-policy out VoiceMap

Configuring Frame Relay Rate Limiting

In addition to guaranteeing a set amount of bandwidth for VoIP, you should
also shape all Frame Relay traffic to ensure that you do not exceed your
service agreement. (You do not need to configure rate limiting if your VoIP
traffic crosses over a PPP connection.)
When setting the committed and excessive burst rate, refer to your SLA with
your Frame Relay provider. The CIR is the bandwidth the service provider
guarantees will be available to the connection at any given moment. The EIR
is the rate at which traffic can burst when the network is uncongested. In this
example, the CIR for the connection to each remote site is 1.5 Mbps. The
provider allows you to burst any amount of traffic, so you could set the
excessive burst rate to the interface's access rate. However, because two PVCs
will be drawing on the same bandwidth, you might want to limit the excessive
burst rate.
First, configure the B to match the CIR:
c
ProCurve(config-fr 1.102)# frame-relay bc 1500000
You can also limit the rate at which the PVC can burst past the committed rate.
For example, you can force the PVC to use no more than two-thirds of the
connection's bandwidth. Set the B to 500 Kbps so that the total available
e
bandwidth will be 2.0 Mbps (determined by summing the B and the B ).
c e
ProCurve(config-fr 1.102)# frame-relay be 500000
