Rate limit problem on E0/1

I have a Cisco 2611 router with IOS version 12.1(5)T9. Ethernet port 0/0 is connected to my 10/100 Mb backbone (a 10/100 switch) and E0/1 is connected to a group of collocated servers. I want to limit the bandwidth of E0/1 to 1.5 Mbs. Below is the configuration that I setup on the E0/1 port. With this configuration the speed from the servers to the client are about 200 - 300 K, which is slower than what is configured.

rate-limit input 1500000 4000 4000 conform-action transmit exceed-action drop

rate-limit output 1500000 4000 4000 conform-action transmit exceed-action drop

If i use just the command below all is well from the client to the servers, but the speed from the servers to the client is unrestricted.

rate-limit output 1500000 4000 4000 conform-action transmit exceed-action drop

I need to restrict the bandwidth to 1.5 Mbs in both directions.

Thanks for any help.

Re: Rate limit problem on E0/1

You should place your rate-limiting statement so that your input statement is on your serial interface on the router and your output statement is on the ethernet interfaces. Look at the following example:

interface Serial1/0

description Serial Interface to Telco

bandwidth 2000000

ip address xxx.xxx.xxx.xxx255.255.255.255

ip access-group 180 in

no ip redirects

no ip unreachables

rate-limit input access-group 114 32000 12000 12000 conform-action transmit exp

no ip mroute-cache

load-interval 30

interface FastEthernet0/0

description Ethernet connection to 3512xl port 1

ip address xxx.xxx.xxx.xxx255.255.255.255

no ip redirects

no ip unreachables

rate-limit input access-group 113 32000 12000 12000 conform-action transmit exp

duplex full

speed 100

Hope this helps.....

Re: Rate limit problem on E0/1

Thanks for the reply.

The only problem with this is that I have other clients on the serial ports. I need to restrict the bandwidth on E0/1 only.
