Re: CE590 http Saving - Page 2

I installed Cisco Content Engine 590 on ISP network

How can I test the performance of the CE590 ??

What is the accepted saving percentage ?

My router show my the following statistics :

I think, the caching performance is not good

What do you suggest ??

Pete,

Thanks for your help

The CE590 saving performance is 30% : 40%

i think this is a good performance

I have a question regarding the CE590

If the internet link is down, and the client open its browser

Should he get the web site from the CE ( browse the cached site ) while the internet link is down ?

Thanks

Pete,

My setup is :

PIX firewall connected between the internal network and the inernet.

All clients & Servers are on the inside network and there are three ISA proxy servers (insdie of the PIX ) which all clients browseres them it for http internet connection.

CE 590 & main router (3661) connectedd the outside of the PIX

Main router 3661 FastEther connected to ouside network of the PIX ( CE 590 on this network also ), and 3661 Serial is connetced to internet.

CE 590 ip address is public address

PIX is doing NAT translation from internal private addresses ( 10.x.x.x ) to public addresses

PTR record with content.uruklink.net to public ip address of the CE590

My CE configuration is :

-----------------------------------

hostname content

!

ip domain-name uruklink.net

!

interface FastEthernet 0/0

ip address 62.32.60.250 255.255.255.0

exit

interface FastEthernet 0/1

shutdown

exit

!

ip default-gateway 62.32.60.254

!

ip name-server 62.32.60.1

!

wccp router-list 1 62.32.60.254

wccp web-cache router-list-num 1

wccp version 2

!

In the Router configuration :

---------------------------------------

ip wccp web-cache

ip cef

and in the Fastethernet connect to PIX outside and CE 590

ip route-cache same-interface

and in the Serial connect to internet

ip wccp web-cache redirect out

Do I have anything missing or wrong in my CE and router configuration ?

Thanks

I should also add to my other comments that you would certainly be better off running 4.1.2 software on the CE as this is much cleaner code with respect to WCCP. I would have to say that this is critical !!

Pete,
