Peak rate and Bc/Betraffic shape

annayuzhao

This the traffic shape I configured and applied on the PVC

--------------------------------------

map-class frame-relay test1

frame-relay traffic-rate 64000 96000

--------------------------------------------------

But show commands confuses me, why sustain is 64000? Isn't sustain meaning Bc, which is

Burst rate /interval? not per second. right

r1#sh traffic-shape

Interface Se0/0.1

Target Byte Sustain Excess Interval Increment

Rate Limit bits/int bits/int ms

64000 5000 64000 32000 125

Thanks

You are configuring the GTS (generic traffic shaping). You need to use "map-class" to define all the parameter for frame-relay traffic shaping.

for example:

map-class frame-relay cisco

frame-relay cir 64000

frame-relay mincir 32000

frame-relay adaptive-shaping becn

frame-relay bc 8000

frame-relay be 16000

Here is the URL with the detailed info:

There are two ways to configure FR traffic shaping , one way is as you said. It's very clear. The other way is what I am doing. Router will auto calculator the Be/Bc and interval based on average and peak rate. See this link.http://www.cisco.com/en/US/tech/tk713/tk237/technologies_tech_note09186a0080094372.shtml

But just the show result doesn't make sense to me.
