We all know improper burst size could result in drops even CIR is not reached. The question is how can we find that optimum burst size which will not cause any drop as CIR approaches on Extreme switch
TEST SET UP:
Traffic Generator------>p3--Extreme_switch--p2 --Accedian_NID ( LOOPBACK)
We are generating 47 MIG stream from the traffic generator.
Extreme switch has following configs:
Create meter METER_CIR
config meter METER_CIR 50000kbs max-burst size 8000kbs
Then we apply the meter on ingress on port 3 using ACL.
Even though the traffic stream is within CIR, we see drops because of improper burst size.
Do we have any formula on Extreme switch that help us find that optimum burst size ?
