Capwap Mailing List: Re: Question about IANA UDP Port Request

[Pat Calhoun (pacalhou) (pcalhoun]

That's a good question. The primary difference, as I understand it, is whether 
a non-root based application could access the port. I suppose that since CAPWAP 
is likely to be implemented on embedded systems, and not on multi-purpose 
computers, then perhaps a reserved port is fine.

Further, since authentication is mandatory to establish the control plane, 
perhaps the actual port number matters less.

Thoughts?

I would like to note that you actually will need to provide a motivation for 
port in the range 0-1023 is needed. What, benefit is there really compared to 
be using one in the range 1024-49151?

Cheers
