How can I implement traffic shapping or CIR using either the Catalyst 2960 or 3750 switches?

Asked by ustda in Network Design & Methodology, Network Switches & Hubs, Cisco PIX Firewall

Tags: , ,

Hello,

I have a requirement to limit the amount of bandwidth used by certain hosts to communicate to the Internet (but not internally from one host to another within the switches).  My network is still in the design phase, so here is what it is shaping up to look like so far:

ISP <-> 2960 Switch (External LAN) <-> ASA 5520 <-> Inside Network.

Say I have a host on the inside - 10.10.10.23 and this host has an external IP statically assigned (on the ASA) of 12.34.45.23 and I want to limit the amount of inbound and outbound bandwidth this host can use when communicating via the gateway (to/from the internet) to only 1.5Mbps (essentially a T1s worth of speed) ...

From the research I've done so far, it seems this is possible using Cisco CIR on the 2960 Switch in the External LAN however I can't seem to find any examples.

Or perhaps that simply isn't the best way - maybe I should use the ASA (if possible) or the 3750 (again, if possible).

Does anyone have any thoughts or examples?  I would think the most logical way to go about it, is to implement this functionality on the External LAN, but I'm probably missing something.

Many thanks,

S
