[netconf] Re: WGLC for udp-client-server

[Andy Bierman <[e-mail]>]

Hi,

This document is ready with the following minor issues:

1) leaf remote-port is optional

   leaf remote-port {
      type inet:port-number;
      description
        "The port number of the remote UDP server.";
    }



Our implementation will reject a missing remote-port leaf in a
receiver-instance.
There is no standard port assignment in this case.
The description should specify that it depends on the context whether this
leaf
can be absent or not.

2) local-port use of 'default 0'

    leaf local-port {
      if-feature "local-binding";
      type inet:port-number;
      default "0";
      description
        "The local port number to bind to when sending UDP
        messages to the remote server. The port number '0',
        which is the default value, indicates that any available
        local port number may be used.";
    }



This usage does not appear to be consistent with the typedef description
for port-number:

      Note that the port number value zero is reserved by IANA.  In
      situations where the value zero does not make sense, it can
      be excluded by subtyping the port-number type.



Is the IANA text supposed to mean "make up any semantics you want for value
zero"?
Not the cleansest modeling I've seen but consistent with coding hacks.
