How to Integrate 500 Series Cache Engine with WS-C3550-48-EMI

[mgoswami]

We are having a Catalyst 3550 L3 Switch, which is being used to provide Internet service. Now we want to integrate a 500 Series Cache Engine so that outbound http traffic is cached.

The Cat 3550-48-EMI switch is not supporting " ip wccp web-cache redirect out" command, instead it's supporting " ip wccp web-cache redirect in" command. So for outbound traffic no caching is happening. How this can be achieved?

in and out means catch traffic when it comes in or when it goes out respectively.

So you can configure the 'out' on the Internet facing interface to catch the request before it goes out to the Internet.

But you can also configure the 'in' on the client interface to catch the request when it comes into the router.

The 'in' gives much better performance because you catch the request before doing a route loockup.

The only disadvantage is that if you have many client vlans, you need to configure this 'in' command for each one of them.
