RE: Query : [DUA] When to send Invalid Interface Identifier Error.

Hi Ankur,
 
I dont see any reason why that error code cannot be used by both SG and
ASP.
The ASP would be correct in sending back this error if the SG is sending
it unsolicited DUA messages about a particular IID.
besides, the handling here should be exactly the same as if the
interface was QPTM, rather than DPTM.
 
Cheers,
Mike

Subject: [Sigtran] Query : [DUA] When to send Invalid Interface
Identifier Error.


Hi,
 
Acc to the IUA RFC section 3.3.3.1
' The " Invalid Interface Identifier " error would be sent by an SG if
an ASP sends a message with an invalid (unconfigured) Interface
Identifier value'
 
I want to confirm that whether the same error should be sent by an ASP
side, if SG sends a message with an invalid (unconfigured) Interface
Identifier value or not. For ex:-
            
X, Y  :- Two Interface Identifier configured at SG 
X :- Single Interface Identifier configured at ASP
 
 
SG(X, Y)                                                     ASP(X)
 
Release Indication( Y) ---------------------------------->  
 
                                <-----------------------------------
Error (Invalid Interface Identifier Y)
 
Is it correct or not, Please confirm
 
Regards
Ank Arora
