RTSP with transparent WCCP.

Hi all.

I want to configure a transparent wccp for traffic tcp between a Ce 7326 and a Cat6509.

I configura on the router an access list with the traffic to be redirect and another with the list of CE.


access-list 109 permit tcp any eq 554

access-list 5 permit (CE IP)

ip wccp 80 redirect-list 109 group-list 5

interface vlan 10

ip wccp 80 redirect out

on CE

wccp router-list 5

wccp rtsp router-list-num 5

wccp version 2

rtsp l4-switch enable

rtsp server cisco-streaming-engine enable

transaction-logs enable

If I do a tcpdump on the CE I son't see packet towards the server that pass to the CE. What is the problem?

Another question. Where can I find the transaction log?




Re: RTSP with transparent WCCP.

Hi Ira,

The configuration of the router and the CE to redirect RTSP is somewhat different than what you have configured.

First, the ACL that you are using in the CAT 6K is not right, due that all you need in the ACL is the client?s source ip address. The WCCP process that is running for RTSP would dynamically select the port for RTSP. Also, you don?t need to declare the CE?s ip address on the ACL.

This link is a good reference for this matter:

So this is the ACL that you should use on the router:

access-list 109 permit tcp any

Second, the router should have this configuration:

(config)#ip wccp 80

(config)#ip wccp 83

(config)#ip wccp version 2

interface vlan 10

ip wccp 80 redirect out redirect-list 109

ip wccp 83 redirect out redirect-list 109

This link explains the configuration of WCCP for all the supported services:

You can check that WCCP is indeed redirecting packets with this command:

?sh ip wccp 80 detail?

?sh ip wccp 83 detail?

Third, on the CE this is the configuration:

wccp router-list 5

wccp rtsp router-list-num 5 l2-redirect

wccp version 2

rtsp proxy media-real license-key installed

rtsp proxy media-real accept-license-agreement

rtsp proxy media-real enable

This link talks about RTSP configuration:

In regards to your question about where the logs are located, you need to do the following:

- go to the exec mode and type: ?#cd logs?

- if you are using RTSP proxy, then type ?#cd real-proxy?

- type ?#dir? to see all the files on this directory.

- If you want to see the latest log file: ?#type working.log?

I hope this helps. Thanks!

Re: RTSP with transparent WCCP.


the problem is that the cE doesn't proxy the request to the RTSP server.

Just only response with te FIN.

what is the problem?



Re: RTSP with transparent WCCP.

Hi Ira,

Try to get a tcpdump on the CE while all this happens so I can look at it. Also, please send me a sh tech from the CE. Thanks!

Re: RTSP with transparent WCCP.


the information yoy request you'll find in the Case SR 605653145 that I open to cisco but that I have not solve yet.

Could you help me?

I have 3 type of file

1) .rm

2) .wmv

3) .3gp that is the most important.

What I need to enable for this kind of traffic in wccp transparent mode?

And what kid of ports I need to open for this type of file?

Do I need to enable the real proxy for this kind of file?

Thanks a lot



Re: RTSP with transparent WCCP.

Hi Ira,

There might be something specific to your network that needs to be revised. Can you take a tcpdump on the CE? Use this command to do so: tcpdump -s 1500 -w dump.cap

To stop the dump, press CTRL + C.

The dump would be stored with the name of 'dump.cap'. Copy it off the CE and attach it for review. I'm sure Tom Jardin would like to take a look at it, so it would be a good idea to attach it the TAC case as well. Thanks!
