Configuring the Option for Handling Message Priorities for Messages Crossing into ITU-I and ITU-N Networks

This procedure is used to configure the option for handling the priority value of messages that cross into ITU-I and ITU-N networks using the chg-ss7opts command with these two parameters.

:msgpri2itui – This parameter specifies the priority value for messages that cross into an ITU-I network. The values for this parameter are:

dflt - The priority value for an MTP-routed message is set to 0. A message routed by Global Title Translation retains the priority value set by the incoming message.
0 - 3 - The priority value for any message crossing into an ITU-I network is changed to this parameter value.

The system default value for the msgpri2itui parameter is dflt.

:msgpri2itun – This parameter specifies the priority value for messages that cross into an ITU-N or ITU-N24 network. The values for this parameter are:

dflt - The priority value for an MTP-routed message is set to 0. A message routed by Global Title Translation retains the priority value set by the incoming message.
0 - 3 - The priority value for any message crossing into an ITU-N or ITU-N24 network is changed to this parameter value. Messages crossing into an ANSI network are not affected.

The system default value for the msgpri2itun parameter is dflt.

These parameters are optional, but at least one of these parameters must be specified in this procedure. If a parameter is not specified, its value is not changed.

Display the existing values for the msgpri2itui and msgpri2itun parameters by entering the rtrv-ss7opts command.
This is an example of the possible output.

MSGPRI2ITUI  dflt

Note:
The rtrv-ss7opts command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-ss7opts command, see the rtrv-ss7opts command description in the Commands Manual.
Change the value of the msgpri2itui and msgpri2itun parameters.
The value specified in this step cannot be the same as the value shown in 1.
If you wish to change the value of the msgpri2itui parameter, specify the msgpri2itui parameter with the chg-ss7opts command. For this example, enter this command.
chg-ss7opts:msgpri2itui=1
If you wish to change the value of the msgpri2itun parameter, specify the msgpri2itun parameter with the chg-ss7opts command. For this example, enter this command.
chg-ss7opts:msgpri2itun=2
If you wish to change the value of both the msgpri2itui and msgpri2itun parameters, specify the msgpri2itui and msgpri2itun parameters with the chg-ss7opts command. For this example, enter this command.
chg-ss7opts:msgpri2itui=1:msgpri2itun=2

When this command has successfully completed, this message should appear.

CHG-SS7OPTS: MASP A - COMPLTD
```
Verify the changes using the rtrv-ss7opts command.
This is an example of the possible output.

Back up the new changes using the chg-db:action=backup:dest=fixed command.

These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

BACKUP (FIXED) : MASP A - Backup starts on active MASP.
BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
