Hello,
I think this should meet the requirements
traffic-shape group 101 16000 2000 14000
16000 it is CIR, so we guarantee 16kb
2000 it is Bc, just number of bit sent
14000 it is Be, so it can burst up to 30kbps but no more, and even after
30kb burst it will be able to send 16kbps.
What do you think about this calculations??

Subject: Generic Traffic Shaping - Fatkid Lab #461
In Fatkid Lab #461, can someone please verify the given solution for
item #5.
Item #5 says:
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.
And the given solution is:
interface Serial0
traffic-shape group 101 16000 32000 32000 1000
access-list 101 permit tcp any any eq telnet
Please correct me if I am wrong, but it seems to me that this does
nothing to guarantee users get at least 16K of bandwidth. In addition,
this traffic-shape command would allow bursts up to the 64k access-rate
and would apply a tc interval of 2 seconds which would be very
inefficient.
I think the solution should read:
interface Serial 0
custom-queue-list 1
traffic-shape group 101 32000 4000 0
access-list 101 permit tcp any any eq telnet
queue-list 1 protocol ip 1 tcp telnet
queue-list 1 default 2
queue-list 1 queue 1 byte-count 100
queue-list 1 queue 2 byte-count 300
Can someone please verify?
Thanks alot! Mike
