<P class=MsoNormal><SPAN class=441013008-22062012>> </SPAN>I have a pq
profile set up w/ 4 q’s, each assigned a rate. According to the manual
when there is no congestion the rate limit should not be imposed, however I am
seeing queue rate being enforced even when no other traffic is offered.
I’m running v 6.1.4.6. <o:p></o:p></P>

<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial

config:</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial
color=#0000ff size=2>Your burst rates don't follow the guidelines from the
manual. So it could be possible, that you've got some unexpected bandwith
rates.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial
color=#0000ff size=2>The manual states, you have to calculate the burst rates as
follows:</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial
color=#0000ff size=2></FONT></SPAN> </DIV>
<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial
color=#0000ff size=2>The burst rate has to be configured as the number of bytes
which are transferred in 1.5sec with the given rate.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=441013008-22062012><FONT face=Arial
color=#0000ff size=2>So if you like to configure a rate of 5Mbit/s your burst
size should be 5000000Bit/s * 1.5 / 8 = 937500 Bytes</FONT></SPAN></DIV>
