Setting The Excessive Burst Rate - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

You can set a B between 0 and 4,294,967,294 bps. For example, if your SLA
c
guarantees a CIR of 1 Mbps, enter:
ProCurve(config-fr 1.101)# frame-relay bc 1000000

Setting the Excessive Burst Rate

The B sets the maximum number of bits that the router can transmit during
e
T. The B determines the rate at which the router can burst data above the
e
committed rate when the Frame Relay network is not congested.
On the ProCurve Secure Router, the B
that the router can transmit, so the upper limit for bandwidth available on the
interface is the sum of the B
Your SLA probably includes terms for bursting traffic past the CIR. Some
providers allow subscribers to burst any amount of traffic. You could set the
B so that, with the B , it equals the physical access rate. You should be aware,
e c
however, that packets transmitted beyond the CIR may be dropped.
Frame Relay switches mark each packet burst past a PVC's CIR with a Discard
Eligible (DE) bit. For example, if a PVC's B
is transmitting traffic at full capacity, then the last 500 Kb of packets will be
marked DE. Frame Relay switches drop DE packets first if the network
becomes congested.
Some service providers do not allow you to burst traffic or only allow you to
burst a limited amount of traffic. A PVC's Excessive Information Rate (EIR)
limits its maximum transmission rate when the network is not congested. If
you have agreed upon an EIR, your service provider may penalize you for
exceeding it.
You should set the B

the following command from the Frame Relay subinterface configuration
mode context:
Syntax: frame-relay be <bits>
For example, your provider allows you to burst 500 Kbps past your CIR, so
you enter:
ProCurve(config-fr 1.101)# frame-relay be 500000
You can set a B between 0 and 4,294,967,294 bps.
