vlan bandwidth limit

[lfgchinadc]

Hello,

     I have one 3560 Layer 3 switch. I want to limit one vlan bandwidth to about 1Mbps. So I configure rate-limit as below:

rate-limit input 800000 100000 200000 conform-action transmit exceed-action drop

rate-limit output 800000 100000 200000 conform-action transmit exceed-action drop

I made tests but the testing clients still can get full speed/bandwidth.

Is there something wrong?

Hi,

     I followed the blog instruction, and I also checked Cisco configuration guide, but still failed.

     I'm checking what is wrong.

Hi,

There have ben a few posts re limiting interfaces on 3560s

Unfortunately you can not use the rate-limit command as it is one

of the many unsupported commands on the 3560.

Please see this link:-

http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_58_se/configuration/guide/swuncli.html#wp1032888

On the interface you can add the egress limiters

!

int fas 0/1

srr-queue bandwidth limit 55

!

This will limit a 100M interface to 55% = 55M

The % can be between 10 -- 90

HTH
