Dear All,
On a router connected to an upstream core ISP, I have configured CAR
limiting all inbound & outbound IP traffic to and from a particular server
only at the rate of 64 Kbps with the following configuration -
interface Ethernet0/0
description ### Link to local LAN ###
ip address 1.1.1.1
ip nat inside
rate-limit input access-group 101 64000 64000 64000 conform-action
transmit exceed-action drop
interface Serial0/0
description ### Upstream Link to Core ISP ###
ip address 2.2.2.2
ip nat outside
rate-limit input access-group 102 64000 64000 64000 conform-action
transmit exceed-action drop
access-list 101 permit ip host 3.3.3.3 any log
access-list 102 permit ip any host 4.4.4.4 log (Assuming this is the NAT public address)
After applying the following config CAR does not seem to work. The "show
interface s0/0 rate-limit" does not indicate any conformed or dropped
packets at all. But the same command shows some packets as conforming at
the ethernet interface. The IOS version used is 12.0-15. The same worked
when I used IOS ver 12.0(7)T.
Is there any problem with CAR, If the rate-limit policy on the WAN
interface points to a NATTED host.
Kindly help me out.
With warm regards,
Vinod.
