Capwap Mailing List: need clarification on UDP ports

[Abhijit Choudhury (Abhijit]

Title: Message

Pat, Mike, Dorothy:

 

I have a question based on v03 of the capwap spec.

In section 3.1, the spec mentions well-known UDP

ports for the CAPWAP control and data packets.

 

There are four kinds of CAPWAP packets:

1. DTLS protected control packets

2. Unprotected control packets

3. Unprotected data packets

4. (Optional) DTLS protected data packets

 

Will there be 4 well-known UDP port numbers ?

 

1, 2 and 3 will be present simultaneously in any

deployment. 3 and 4 may co-exist in a deployment

if some data channels are encrypted and some not.

There has to be a way to distinguish these four

kinds of packets.  The draft is not clear about how

this is done.

 

Thanks,

   Abhijit
