this is one of many right answers as this exercise is worded:
traffic-shape group <access-list #> <target - bps> <bits per INTERVAL, sustaine
d> <bits per INTERVAL, excess> <buffer limit, usually defaulted>
bits per interval determines the interval. So in this case, 32000 means the in
terval that the traffic shaping is managed to is 2 seconds (32000 bits per inte
rval divided by 16000 bps).
the ratio of the 2 bit-per-interval values determine the excess compared to the
average. So in this case, we have 16000 bps target 32000 bits per interval =
16000 bps over a 2-second interval sustained, 32000 bits per interval = 16000 b
ps excess. So that's 16k average, 32k max.
But how about if we were given the same task, but also told the measurement int
erval should be 1/4 of a second? the command would be
traffic-shape group 101 16000 4000 4000
16k bps, 4k average per interval so my interval=.25 second, 4k excess per .25-
second interval.

Hello
Can someone explain if the following is correct
The example is from FatKid exercise 461 Queuing and Perf.
5. Configure R3 so that users on the Token Ring segment get at least 16K
of
bandwidth, but not more than 32K, for their telnet traffic, and the
remaining bandwidth
for everything else.
Answer as per FatKid is:
traffic-shape group 101 16000 32000 32000 1000
R3#sh traffic-shape
Access Target Byte Sustain Excess Interval

Se0 101 16000 8000 32000 32000 2000
4000 -
Is this correct?
What is sustained rate ? and how do you calculate it ?
32000 bits can be sent in 2000 ms, which is the interval, 2000 ms= 2
sec, so in 1 sec it is 16000
Why is the measurement interval longer than 1 sec? can I change it?
