CE-590 and Router

[kozinyy]

I have a stand-alone CE-590 connected to 72xx ISP router,located outside of our PIX. When WCCP service is enabled, download speed (tested using DSLExtreme site) is about 11MB, but if WCCP is disabled (or simple unplugged cable from CE), then download speed jump to 22MB.

The part of config is below:

Router:

ip wccp web-cache

ip wccp 53

ip wccp 91

ip wccp 98

interface FastEthernet0/0

ip address XXXX XXXX

ip route-cache same-interface

interface Serial3/0

ip wccp web-cache redirect out

ip wccp 53 redirect out

ip wccp 91 redirect out

ip wccp 98 redirect out

CE-590

wccp router-list 1 XXXX

wccp web-cache router-list-num 1 l2-redirect

wccp custom-web-cache router-list-num 1 port 8080 l2-redirect

wccp rtsp router-list-num 1

wccp dns router-list-num 1 l2-redirect

wccp version 2

Any help will be appreaciate.

Hi Yefrem,

no nothing needs to be configured on the router except the permission to access the CE on port i.e 3128.

One additional configuration has to be done on the CE:

http proxy incoming 3128 (this will make the CE listen to proxystyle request destined to Port 3128.

After that configure your browser to use a proxy. The settings are (IP-Address of the CE port 3128 if you use 3128). Please do not use 80 as proxy port as this will be intercepted by WCCP.

Cheers,

Joerg

Yefrem,

found nothing interesting in the 22mb-fast one.

[looks like you sniffed a part of the network where there was no traffic].

One thing interesting in the slow trace is that I noticed you are doing file upload to test the speed of the transfer.

The cache will not cache those objects and the presence of the cache will definitely make the upload slower since the traffic has to be forwarded to the cache and the cache needs to send it back to the router.

I would suggest to test download, and try to download multiple time the same file.

The goal of the cache is increase speed once the object has been cached.

The first download will always be slower.

Regards,

Gilles.

WCCP by default uses the highest numbered interface in the router. To provide a consistent interface from a troubleshooting standpoint (it does not impact functionality), some people set up a loopback. That way- the WCCP router interface is in theory always the same. Does this help?

My understanding of WCCP would indicate that while you have the ports listed as ip wccp 53 etc., you still need to assign them to a service-number. For instance web-cache is service-number 0. Without assigning both a service number to the ports, (which could be service-number 53 for port 53 as an example), and then creating that service number rule on your cache box, these would never use WCCP for caching. That is my understanding at least.
