Traffic Shaping at 10ms sustained burst

[v_michael_]

Hello,

I noticed that on the 881 router, the lowest sustained burst value is only 25ms. However, on the 871, the lowest value is 10ms. The issue is that 10ms is the recommended value for voice traffic. So far, I haven't had any luck with finding any documentaion on this change. Does anyone know why this was changed? Is there a work around on the 881 to make it accept and support 10 ms? Thanks!

My 881 router information:

SRST881 - 12.4(24)T3

I've tried 2 configurations below, to now avail:

1) Config generated error below.

router# shape average  768000 7680 
---> Shaping Interval is 10 milliseconds. Intervals below 25 milliseconds rejected

2) The only option is 25ms.

router# shape average percent 100 ?
--->  <25-2000>  sustained burst in milliseconds.

Hi,

Could you please double check on the IOS version?

this issue should have been taken care off via  bug : CSCtb00695

thanks,

The bug description makes sense. I'll test the config with the 25ms value. Thank you!
