Solution 2296788.1 : SRI_SMS Messages Are Not Forwarded As Expected Despite the MAP Screening Configuration

Applies to:

Oracle Communications EAGLE (Software) - Version EAGLE 3x.x and later
Information in this document applies to any platform.

Symptoms

The customer has configured a MAP screening to have all incoming SRISM from the linkset LS01 to be diverted to the destination 2017.
However, the SRISM are still routed to the original destination 2015.

Cause

There must necessary be a mistake in the Eagle configuration done by the customer.
The "MAP screening" configuration will forward the incoming messages if the configuration is coherent with the incoming messages.

For information, below the customer configuration :

> rtrv-ls:lsn=ls01

Solution

The incoming SRISM have SSN=8 in the CgPA and SSN=6 in the CdPA.
The configured MAP screening for the SSN parameter is as below :

> rtrv-gsmssn-scrn

eaglestp 17-08-13 16:09:55 IST EAGLE 46.4.0.0.0-69.19.0
SSN ORIG DEST
8 Yes Yes

Therefore Eagle will only apply the MAP screening rules on MSUs having SSN=8 for both CgPA and CdPA. This is why it does not work.

Please change the "gsmssn-scrn" configuration to have this :

> rtrv-gsmssn-scrn

eaglestp 17-08-13 16:09:55 IST EAGLE 46.4.0.0.0-69.19.0
SSN ORIG DEST
8 Yes No

OR this :

> rtrv-gsmssn-scrn

eaglestp 17-08-13 16:09:55 IST EAGLE 46.4.0.0.0-69.19.0
SSN ORIG DEST
6 Yes Yes
8 Yes Yes
