Rate-Limit Help!!!

Hi I am current having difficulty with a section of CAD operators who need to download CAD drawings all day long (on a 512k connection). I have applied the following ACL and Limits on Serial0.01:

rate-limit input access-group 101 512000 24000 32000 conform-action set-prec-transmit 5 exceed-action set-prec-transmit 0

rate-limit input access-group 102 256000 24000 32000 conform-action set-prec-transmit 5 exceed-action drop

rate-limit input 256000 16000 24000 conform-action set-prec-transmit 5 exceed-action drop

rate-limit output access-group 101 512000 24000 32000 conform-action set-prec-transmit 5 exceed-action set-prec-transmit 0

rate-limit output access-group 102 256000 24000 32000 conform-action set-prec-transmit 5 exceed-action drop

access-list 101 permit tcp any any eq www

access-list 102 permit tcp any any eq ftp

The problem I have is that all traffic regardless of who it is from is restricted by this. Is it possible to allow devices such as my servers no rate-limit, say via IP or MAC address? If so can somebody forward me the CL for this?

Thanks, Mark

Re: Rate-Limit Help!!!

Hi,

Just include the ips that you need to deny from the rate limit , then just add a deny statement before

access-list 101 deny host x.x.x.x any

access-list 101 permit tcp any any eq www

Hope this helps

Re: Rate-Limit Help!!!

I'm actually really lost on this one and finding it hard to get my head round it!!!

Re: Rate-Limit Help!!!

Hi ,

Pls use " access-list 101 deny ip host x.x.x.x any"

But if you alreay have a acl 101 defined , the newly added one would get added next.

If your access-list is numbered one then

sh ip access-list 101

10

20

then

ip access-list extended 101

5 deny ip host x.x.x.x any

Or else u need to remove the CAR first , then delete the ACL , add the new ACL and apply the CAR

regards
