Quick Limiter Bust Question…

LuckyURE

Hello,

I'm using 2.1 and set limiters as follows:

IN: 5 Mbps with a burst of 15 Mbps (Source Addresses with blank masks)

OUT: 5 Mbps with a burst of 15 Mbps (Destination Addresses with blank masks)

The idea here is so that each user can burst upwards of 15 Mbps for a bit and then be throttled down to 5 Mbps so as not to hog the pipe. My question is, and I can't seem to find the simple answer anywhere, is: What is the default setting for the burst? That is, how long will a user's connection burst at 15 Mbps before they are throttled down to 5 Mbps?

Thanks y'all for your help and keep up the great work!

how about what is your

IN:?
out: 5000

Bursting isn't set right in the rules on any release. Fixed by this:

Burst is always in Bytes, a fixed size, NOT a throughput. So it's not possible to set a burst of X Mbit/s, but you could set one for 5,000,000 (~5MBytes)

As always, thanks for the help. Now I understand the weird numbers I'm seeing it all makes perfect sense. Thanks!

Hello Jimp,
Why then when I enter 2048000 into the GUI burst field does the Limiter Info report 2048000 k? Isn't 2048000 k = 2048000000 bytes or 2048 Mbytes?

I can't seem to get bursting to work no matter the number. All traffic hitting the limited rule is capped at the bandwidth value. I'm using one parent limiter without child and no mask bits.

Limiters:
BKT Prot Source IP/port Dest. IP/port Tot_pkt/bytes Pkt/Byte Drp
00001: 384.000 Kbit/s 0 ms burst 2048000 k
q131077 50 sl. 0 flows (1 buckets) sched 65541 weight 0 lmax 0 pri 0 droptail
sched 65541 type FIFO flags 0x1 256 buckets 48 active
mask: 0x00 0xffffffff/0x0000 -> 0x00000000/0x0000_

Are you sure? Looking at the information presented by diagnostic status in 2.1.2, the figure entered for burst in the limiter dialog is interpreted as Mbytes.
