Rate-Limit question 1

[tombert]

Hello all,

The rate-limit command you can set cir normal burst and excess burst..

configuration

interface Serial0/0/0.1 point-to-point
description at&t frame/relay
ip address 10.x.x.x 255.x.x.x
ip access-group 109 out
ip verify unicast reverse-path
no ip redirects
no ip unreachables
rate-limit input access-group 154 96000 18750 37500 conform-action transmit exceed-action drop
rate-limit output access-group 154 96000 18750 37500 conform-action transmit exceed-action drop
no cdp enable
frame-relay class shapefor256
frame-relay interface-dlci xxx

I am rate limiting this interface with an access group 154.
In that group I have various ip's hosts etc.. as a permit.

Now my question is .. does the rate-limit apply to all traffic under that access list 154 ? or as an individual rate-limit to each ip, host , etc..? So if I have 10 PC's in use , does each get a peice of the 96 or does each use 96 ?

Any devices/subnets/ports that are permitted within acl 154 will get rate limited to 96k. The policy doesn't care if one user uses all the 96k or if 10 users combine to use 96k, it will simply ensure the sum total of utilisation from devices permitted in the acl are rate limited to 96k.

Any devices/subnets/ports that do not belong to or are denied in the acl will not get rate limited.

If you want more granularity regarding how much utilisation a particular user should have, you can define as many rate limit statements as you want and apply them all to the same interface.

Hope this helps
