WCCP web-cache VS service numbers

Hello,

I am working on WCCP configuration for our LAN and I have been wondering if there is any difference in functionality between using "ip wccp web-cache" or "ip wccp [service number]"?

(The plan is to have caching appliances and by using WCCP, the web traffic would be picked up and sent to the caching engines.)

Thank you for your time.

Hi Martin,

The WCCP service numbers are different from the TCP port numbers,  in the case of the wccp web-cache , this is going to redirect all the traffic from TCP port 80 from routers to Cisco Cache/ACNS devices.  Other third-part WCCP clients will use custom wccp number (90 - 97) ,  some of the most commons wccp service groups are showed below,  :

Service   NameService NumberProtocolPortPriority
web-cache0tcp80240
dns53udp53202
ftp-native60tcp200
tcp-promiscuous61tcp*34

Hello Rubens,

thanks for the spot on information. I was trying to find a website with the full spectrum of the service groups and couldn't find any. Can you provide a link for anything like that? Also regarding the priority I assume the lower number means higher priority? (based on that WAAS uses 61 and 62)

Thank you

Hi Martin,

You might want to check the WCCP RFC to get more info,  the Cisco documentation will have the same list as the one I sent you,  as these are the wccp service-group range that Cisco wccp clients are using.  As for the WCCP priority, each WCCP service group will have its own priority,  higher priority means the packet once hit the interface with wccp enabled  will be first matched to that particular wccp service.

Thank you

Rubens
