Current status of WCCP support
Hi,
I've been experimenting with WCCP support in ATS and had some questions.
What is the current status of this support? Is it still under active development or is it considered "done"?
I'm trying to use it with a gre tunnel and it is not registering with the router properly. Based on my (limited) understanding of WCCP (and comparing it to an alternative implementation) it appears to be doing the wrong thing. If I were to try and fix this how safe is it to *not* maintain the existing behaviour?
If I were to make changes it's unlikely I'd get time to do so for a while (say, at least a year). Given the current rate of development in this area would you expect anything to change in that time? Or can I assume that things will stay pretty much as they are currently?
Thanks,
Jonathan.

Hi Alan,
It is my fault.
With the config line below:
LOCAL proxy.config.wccp.addr STRING "192.168.0.211"
The traffic_manager can not parse the ADDR but no error log.
[Nov 30 23:38:15.158] Manager {0x7f309db73740} NOTE:
[LocalManager::LocalManager] WCCP identifying address set to

With the config line below:
LOCAL proxy.config.wccp.addr STRING 192.168.0.211
The traffic_manager can parse the ADDR and everything is ok.

Re: Current status of WCCP support

That's very odd, since traffic_wccp and traffic_manager link literally the same code to perform WCCP operations. Any chance you can get a packet capture of the two HERE_I_AM packets for comparison?

The traffic_manager and traffic_wccp is different.
It seems traffic_manager not working properly.
I will try "ip wccp web-cache" with "STANDARD" in wccp.config later.

The traffic_manager and traffic_wccp is different.
It seems traffic_manager not working properly.
I will try "ip wccp web-cache" with "STANDARD" in wccp.config later.

Hi Alan,
1) ./configure with "--enabled-wccp"
2) The WCCP configuration in records.config
proxy.config.wccp.addr STRING 192.168.0.1 // the wccp router ip
proxy.config.wccp.services STRING /path/to/wccp.config
The wccp.config is setup by guide
https://docs.trafficserver.apache.org/en/latest/admin-guide/configuration/transparent-proxy/wccp-service-config.en.html
I will setup a WCCP environment and try it again.

Re: Current status of WCCP support
Posted by Alan Carroll <so...@yahoo-inc.com.INVALID>.
As far as I know, WCCP is considered a finished feature and there is no ongoing development. It is still just WCCP V2 because, AFAIK, WCCP V3 was never released. I haven't used it for a while but I don't see what would have broken it. Did you (1) --enable-wccp and (2) install a WCCP configuration file for ATS?

I tried to setup WCCP with ATS 6.0.x but it did not work correctly.
I really need it work correctly in Q1, 2017.
It will be great if you could share any document or guidelines to support
me.
BTW, do you known which ATS version the WCCP worked correctly ?
Thanks.
