Adding a Loopset

This procedure is used to add a loopset to the database using the ent-loopset command.

The ent-loopset command uses these parameters.

:name - The name of the loopset. The loopset name can contain up to 8 characters, with the first character being a letter.

:pc1/pc1a/pc1i/pc1n/pc1n24 - The point codes assigned to the specified loopset, either an ANSI point (pc1/pc1a), ITU-1 or ITU-1 spare point (pc1i), a 14-bit ITU-N or 14-bit ITU-N spare point code (pc1n), or a 24-bit ITU-N (pc1n24) point code.

Note:

See Chapter 2, Configuring Destination Tables in Database Administration - SS7 User's Guide for a definition of the point code types that are used on the EAGLE and for the definition of the different formats that can be used for ITU national point codes.

:mode - Mode of operation. Can be notify or discard. This is an optional parameter that specifies whether the message is discarded when an SCCP loop is detected. The "Notify only" mode of operation generates UIMs but not actually discard the message, which allows a user to capture and verify messages. However, the "Discard" mode of operation generates the UIMs and also discard the MSUs.

To add a loopset to the database, the SCCP Loop Detection feature must be enabled. The rtrv-ctrl-feat command output shows whether or not the SCCP Loop Detection feature is enabled. If the SCCP Loop Detection feature is not enabled, perform the Activating the SCCP Loop Detection Feature procedure to enable this feature.

All the point codes specified with the pc1/pc1a/pc1i/pc1n/pc1n24 parameter must be the same type of point code. The point code values are separated by commas with no spaces between the commas and the point code values as shown in the example pc1=002-002-002,003-003-003,004-004-004. This example specified three ANSI point codes for the loopset.

A maximum of twelve point codes can be assigned to a single loopset. However, this procedure can be used to assign a maximum of six point codes to a single loopset. If you wish to add more point codes to the loopset entries, perform the Changing the Attributes of a Loopset procedure.

A maximum of 1000 loopsets can be assigned to a loopset database. If adding the new loopset entries exceed the maximum capacity of the loopset table displayed in the rtrv-loopset command output, entries in the loopset table must be removed to ensure that the new loopset entries can be added. Perform the Removing a Loopset procedure to remove the required number of loopset entries

Display the loopsets in the database by entering this command.
rtrv-loopset:num=1000:force=yes
This is an example of the possible output.

LOOPSET table is (1 of 1000) 1% full
```
Note:
If the rtrv-loopsetcommand is entered with no other parameters specified, a maximum of 50 entries are displayed. To display more than 50 entries, the force=yes parameter must be specified with the rtrv-loopset command and the num parameter value must be greater than 50. Since there can be a maximum of 1000 loopsets in the database, to display all the loopsets in the database, the force=yes and num=1000 parameters must be specified with the rtrv-loopsetcommand.
If error message E4565 is displayed after the rtrv-loopsetcommand is executed, the SCCP Loop Detection feature is not enabled.

If the SCCP Loop Detection feature is not enabled, perform the Activating the SCCP Loop Detection Feature procedure to enable the SCCP Loop Detection feature. If error message E2584 is displayed after the rtrv-loopsetcommand is executed, the GTT feature is not on. Perform the Activating the SCCP Loop Detection Feature procedure to turn the GTT feature on and enable the SCCP Loop Detection feature.
The EAGLE can contain a maximum of 1000 loopset. If the rtrv-loopset output in step 1 show 1000 loopsets, enough loopsets must be removed from the database to allow the new loopsets to be added.

Perform the Removing a Loopset procedure and remove the required number of loopsets to allow the addition of the new loopsets. If no loopsets are removed, the new loopsets cannot be added and this procedure cannot be performed.
Add the loopset to the database using the ent-loopsetcommand.

For this example, enter this command
ent-loopset:name=rtp2:pc1=2-2-2,3-3-3,4-4-4,5-5-5

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

LOOPSET table is (12 of 1000) 1% full
ENT-LOOPSET: MASP A - COMPLTD
```

Verify the changes using the

rtrv-loopset

command with the loopset name specified in step 4.

For this example, enter this command.

rtrv-loopset:name=rtp2

This is an example of the possible output.

Backup 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.

A loopset can contain a maximum of 12 point codes. If you wish to add more point codes to this loopset, perform the Changing the Attributes of a Loopset procedure and add the additional point codes with the apcl/apcla/apcli/apcln/apcln24 parameter.

If you do not wish to add more point codes to the loopset, this procedure is finished.
