Configure WCCP on a 4510 switch

I have to configure an instance of a WCCP on a 4510 switch and I have to admit  have read the examples given by Cisco but dont have understanding of the example config

Router(config)#

ip wccp web-cache group-address 224.1.1.100 password alaska1

I have attached the config in question above and could someone please clarify what the group address  224.1.1.100 is ?

Many Thanks

Mark

The group list is for a group of proxy servers not to define which user traffic goes to the proxy.

Can you -

1) use a different number for your service group

and

2) use the config i supplied with "redirect-list"

I just checked the configuration guide and it appears that there is no way to define which clients are redirected to the proxy ie. you apply the redirect to a client SVI and then all clients in that vlan are redirected to the proxy.

This is different from say the 3750 where you can use an acl for the users and specify it in a redirect-list.

The group-list option is used where you have multiple proxies and you only want some of them used.

So you need to just apply "ip wccp 99" to the client SVI and all clients in that vlan will be proxied.

I will check to see if later IOS versions on the 4500 support a redirect-list. But at the moment it looks like it's all or nothing ie. all clients in the vlan are proxied or none are.

You weren't the only one

That's the thing with hardware swithches ie. there are always differences between each model.

Seems a bit of a limitation ie. all clients in a vlan or none but i suppose the theory is if you are using a proxy you probably want all clients to use it.

Would still prefer to be able to choose though.
