The more i learn the more i get confused on FRTS.
i am taking this from scratch !!
what is EIR :
As per my understanding
EIR = CIR - minCIR
Total bucket = CIR + Be
and Be = EIR (at 1 sec)
is the above correct !!
now i am taking an example :
i want to buy 64k link and must be able to burst on a double when FR is
free :
So my maths will be :
minCIR = 64k
CIR = 128k
Tc = 0.125
Bc = minCIR * 0.125
Be = CIR * 0.125
Now i have 2 way to feed the values into my router
1 - by giving the seprate values in map-class
2 - by using "frame-relay traffice-rate"
1 -
map-class frame-relay FRTS-1
frame-relay cir 128000
frame-relay be 16000
Interface Se0
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
100 128000 4000 128000 16000 125 2000 -
2 -
map-class frame-relay FRTS-2
frame-relay traffic-rate 128000 144000 <---- CIR + (CIR + (Be or EIR) )
that is 128000 + 16000 = PEAK
no frame-relay adaptive-shaping
Interface Se1
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes)
Active
200 128000 4000 128000 16000 125 2000 -
Please confirm if the above configs are correct !!
