Changing the Default GTT Mode Options

This procedure is used to change the default GTT mode options using the chg-sccpopts command with these parameters.

:dfltgttmode – the system default of the GTT mode hierarchy for the EAGLE to follow when performing global title translation. The values for this parameter are shown in Table 4-50 .

:dfltfallback – the default fallback option - the action that is taken if the last translation does not match when performing global title translation using a Flexible Linkset Optional Based Routing specific GTT mode. This parameter has two values.

• no - Global title translation fails and the message is discarded.
• yes - Global title translation is performed in the message based on the last matched entry.

This procedure can be performed only if the Origin-Based SCCP Routing feature is enabled or if the Flexible Linkset Optional Based Routing feature is enabled and turned on.

For more information about the default GTT mode options, refer to the Origin-Based SCCP Routing or Flexible Linkset Optional Based Routing sections.

1. Display the existing default GTT mode values by entering the rtrv-sccpopts command.

   This is an example of the possible output.

   SCCP OPTIONS
   -------------------------------
   DFLTGTTMODE                CdPA
   DFLTFALLBACK                yes

   The rtrv-sccpopts output contains other fields that are not used in this procedure. If you wish to see these fields, refer to the rtrv-sccpopts command description in CommandsUser's Guide.

   To change the DFLTFALLBACK value to yes, the Flexible Linkset Optional Based Routing feature must be enabled and turned on. If the current DFLTFALLBACK value is yes, the Flexible Linkset Optional Based Routing feature is enabled and turned on.

   To change the DFLTGTTMODE value to one of these values (a Flexible Linkset Optional Based Routing GTT mode hierarchy), the Flexible Linkset Optional Based Routing feature must be enabled and turned on. If any of these values are shown in the rtrv-sccpopts output for the DFLTGTTMODE option, the Flexible Linkset Optional Based Routing feature is enabled and turned on.

   • FLOBRCdPA
   • FLOBRCgPA
   • FLOBRCgPA,FLOBRCdPA
   • FLOBRCdPA,FLOBRCgPA

   To change the DFLTGTTMODE value to one of these values (an Origin-Based SCCP Routing GTT mode hierarchy), the Origin-Based SCCP Routing feature must be enabled and turned on. If any of these values are shown in the rtrv-sccpopts output for the DFLTGTTMODE option, the Origin-Based SCCP Routing feature is enabled and turned on.

   • CgPA
   • AdvCdPA,CdPA
   • AdvCdPA,CgPA,CdPA
   • AdvCdPA,CdPA,CgPA
   • CgPA,AdvCdPA,CdPA
   • CgPA,CdPA
   • CdPA,CgPA

   The DFLTGTTMODE or the DFLTFALLBACK values must be changed in this procedure.

   Continue the procedure with 4 if:

   • The DFLTGTTMODE value will be changed to an Origin-Based SCCP Routing GTT mode hierarchy value; a value for one of the Origin-Based SCCP Routing GTT mode hierarchies (other than CdPA)is shown in the rtrv-sccpopts output; and the DFLTFALLBACK value will not be changed.
   • The DFLTGTTMODE value will be changed to a Flexible Linkset Optional Based Routing GTT mode hierarchy value and a value for one of the Flexible Linkset Optional Based Routing GTT mode hierarchies (other than CdPA) is shown in the rtrv-sccpopts output. The DFLTFALLBACK value can also be changed to yes.
   • The DFLTGTTMODE and the DFLTFALLBACKvalue will be changed to these values.
     • DFLTGTTMODE - CdPA
     • DFLTFALLBACK - no
   • Only the DFLTFALLBACK value is changed to no.

   If the DFLTGTTMODE value is being changed to an Origin-Based SCCP Routing GTT mode hierarchy, and a value for one of the Origin-Based SCCP Routing GTT mode hierarchies (other than CdPA) is not shown in the rtrv-sccpopts output, continue the procedure with 2.

   If the DFLTGTTMODE value is being changed to a Flexible Linkset Optional Based Routing GTT mode hierarchy, and a value for one of the Flexible Linkset Optional Based Routing GTT mode hierarchies (other than CdPA) is not shown in the rtrv-sccpopts output, continue the procedure with 3.

   If the DFLTFALLBACK value is being changed to yes, and a value for one of the Flexible Linkset Optional Based Routing GTT mode hierarchies (other than CdPA) is not shown in the rtrv-sccpopts output, continue the procedure with 3.

2. Display the status of the Origin-Based SCCP Routing feature by entering this command.

   rtrv-ctrl-feat:partnum=893014301

   This is an example of the possible output.

   rlghncxa03w 10-07-07 00:29:31 GMT EAGLE5 42.0.0
   The following features have been permanently enabled:
   
   Feature Name              Partnum   Status Quantity
   Origin Based SCCP Routing 893014301 on     ----
   
   
   The following features have been temporarily enabled:
   
   Feature Name              Partnum   Status Quantity   Trial Period Left
   Zero entries found.
   
   
   The following features have expired temporary keys:
   
   Feature Name              Partnum
   Zero entries found.

   If the Origin-Based SCCP Routing feature is not enabled or turned on, perform Activating the Origin-Based SCCP Routing Feature to enable and turn on the Origin-Based SCCP Routing feature.

   After Activating the Origin-Based SCCP Routing Feature has been performed, or if the rtrv-ctrl-feat output shows that the Origin-Based SCCP Routing feature is enabled and turned on, continue the procedure by performing one of these steps.

   • If only the DFLTGTTMODE value is being changed to an Origin-Based SCCP Routing GTT mode hierarchy (other than CdPA), continue the procedure with 4.
   • If the DFLTFALLBACK value will be changed to yes, and a value for one of the Flexible Linkset Optional Based Routing GTT mode hierarchies (other than CdPA) is not shown in the rtrv-sccpopts output, continue the procedure with 3.
3. Display the status of the Flexible Linkset Optional Based Routing feature by entering this command.

   rtrv-ctrl-feat:partnum=893027701

   This is an example of the possible output.

   rlghncxa03w 10-07-07 00:29:31 GMT EAGLE5 42.0.0
   The following features have been permanently enabled:
   
   Feature Name              Partnum   Status Quantity
   Flex Lset Optnl Based Rtg 893027701 on     ----
   
   
   The following features have been temporarily enabled:

   Zero entries found.
   
   
   The following features have expired temporary keys:
   
   Feature Name              Partnum
   Zero entries found.

   If the Flexible Linkset Optional Based Routing feature is not enabled or turned on, perform Activating the Flexible Linkset Optional Based Routing Feature to enable and turn on the Flexible Linkset Optional Based Routing.

   After Activating the Flexible Linkset Optional Based Routing Feature has been performed as needed, or if the rtrv-ctrl-feat output shows that the Flexible Linkset Optional Based Routing feature is enabled and turned on, continue the procedure with 4.

4. Change the default GTT mode values using the chg-sccpopts command and with at least one of the parameters and values shown in Table 4-50.

   Table 4-50 Default GTT Mode Option Parameter Combinations

   The rtrv-sccpopts output contains other fields that are not used in this procedure. If you wish to see these fields, refer to the rtrv-sccpopts command description in Commands User's Guide.

6. 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.
