Hello,
I am working through the below question and I am unsure about how to
interpret one aspect. When it says "maximum throughput is 128kbps"
would configuring the cir of 128k satisfy the requirement? Also I am
unsure if i should include a Be value.
"Configure the r3 frame-relay interface for rate limiting by
configuring the parameters cir, bc, mincir
- Maximum throughput is 128kbps
- During congestion, your provider will mark any traffic in excess of
48kps as de
- Adapt to becns only
- Your token buck interval is 125ms
- Use a map-class to apply this feature to all pvcs"
My understanding of how to derive the be value is Be = (ar cir) * tc
12800 48000 = 80000 = 10000 Be in this case. However the question
doesn't explicitly ask for it, should i include it anyway?. Would just
setting the cir to 128k and the bc to 16k be valid in your opinion?
My solution ->
!
map-class frame FRTS
frame-relay adaptive-shaping becn
frame-relay cir 128000
frame-relay min-cir 48000
frame-relay bc 16000
!
int s0/0
frame-relay traffic-shaping
frame-relay class FRTS
