Re: frame-relay traffic-rate command, does it work?
When you use the command:
frame-relay traffic-rate 640000 1024000
the router implements its own values for bc, be and tc etc.
Effectively your mincir becomes 640000 (divided by the number of intervals per second) and the router will set up a value for be. It will actually send out bc + be worth of data in the first time interval. From that point onwards it will not send out any be (excess burst) until it has built up credits.
Credits are built up only when the router actually sends out data at less than bc. If you constantly have data that requires to be sent out, you will never build up credits and therefore never go past 640000 over an extended period of time.
Since Telsta is always generous try using the following values (after getting rid of the frame-relay traffic-rate 640000 1024000 command)
map-class frame-relay Jam
frame-relay adaptive-shaping becn
This will set up the line with an average rate of 1024K and will throttle back on receiving BECNs back to a minimum of 640000. If you find you are getting too many BECNs try reducing CIR and bc a little e.g 960000 and 120000 and increasing be to 64000. This will try to average 960000 and burst up to 1024000.
There are a few URLs on CCO with regards to tc, bc and be and how they are used.
