Re: Limit bandwidth on some ports - Cisco 3750

Hallo,

How can I limit speed on an interface of a Cisco 3750 Switch.

I looked for some solutions, but nothing worked. Is it possible to give some tips.

I would be used in a datacenter. Some client only need 1Mbit, others need 3Mbit and so on.

Thx to everyone who can help me out.

Notmally, I would suggest doing this via an "access-list rate-limit" command. However, that command is unsupported on the 3750 itself due to hardware limitations. (reference http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3750/12225sea/3750scg/swuncli.pdf). That is assuming you are using the 3750 for Layer 3 services in your configuration.

You could alternatively look into using queueing (and the associated policing functions) to achieve your goals. See http://www.cisco.com/en/US/products/hw/switches/ps5532/products_white_paper09186a00801eb831.shtml for a reference guide.
