Cisco 857 rate-limit

azaghul

Hi,

Not really a CCNA question, but wasn't sure which forum was appropriate.

Have had my 857W (IOS advsecurityk9-mz.124-15.T10) running for some time, recently changed to an 8Mb ADSL1 plan and if the download speed exceeds 725KBs (average) the router resets. I'm guessing it's suffering from a buffer over run and looses the plot.

I've tried applying

[FONT=Courier New]rate-limit input 7000000 7000000 7000000  conform-action transmit  exceed-action drop[/FONT]

to the ATM and Dialer interfaces, but no success.

Have seen ways to limit speed by time of day (this would be ideal for peak/offpeak limits) but they can only be applied via class/policy maps which the 857's don't seem to support.

I've spent the past few hours searching for an answer without success...

Any advice appreciated:D

You're going about this the wrong way. What you need to do is find out why its crashing since it shouldn't do that.

Plug a PC into the console port and get it to crash so you can get a log of the errors.

The latest IOS for a 857 is 12.4.15T12 and the latest (and only) ADSL chipset firmware is 4.0.18 but that only appears to apply if you're in the UK and using BT ADSL.
