Configuring the EAGLE for the CNCF Feature

To configure the EAGLE for the CNCF feature, gateway screening rules for Allowed OPC, Allowed DPC, and the Allowed SIO entities must be configured in the database for this feature. The last entity in the screening process (nsfi=stop) must have a gateway screening stop action set containing the CNCF gateway screening stop action.

The allowed OPC screening rules must contain the OPCs that the ISUP IAM messages are being sent from.

The allowed DPC screening rules must contain the DPCs that the ISUP IAM messages are being sent to.

The allowed SIO screening rules must contain the ISUP message type, defined by the si=5 parameter.

The CNCF feature must be turned on. Before the CNCF feature can be turned on, the gateway screening feature must be on. This can be verified with the rtrv-feat command.

The examples in this procedure are based on these figures and tables.

Canceling the RTRV-LS Command

Because the rtrv-ls command used in this procedure can output information for a long period of time, the rtrv-ls command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-ls command can be canceled.

  • Press the F9 function key on the keyboard at the terminal where the rtrv-ls command was entered.
  • Enter the canc-cmd without the trm parameter at the terminal where the rtrv-ls command was entered.
  • Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-ls command was entered, from another terminal other that the terminal where the rtrv-ls command was entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

  1. Verify that the gateway screening and the calling name conversion facility features are on, by entering the rtrv-feat command.

    If the gateway screening feature is on, the GWS field should be set to on. If the calling name conversion facility feature is on, the CNCF field should be set to on. For this example, the gateway screening and the calling name conversion facility features are off.

    Note:

    Thertrv-feat command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by thertrv-feat command, see thertrv-feat command description inCommands User's Guide.

    If both features are on, go to step 4. If the gateway screening feature is on, but the calling name conversion facility feature is off, go to step 3. If the gateway screening feature is off, go to step 2.

  2. If the gateway screening feature is not on, shown by the GWS = off entry in the rtrv-feat command output in step 1, turn the gateway screening feature on by entering this command.

    chg-feat:gws=on

    Note:

    Once the gateway screening feature is turned on with thechg-feat command, it cannot be turned off.

    When the chg-feat has successfully completed, this message should appear. 

    rlghncxa03w 06-10-25 15:26:30 GMT EAGLE5 36.0.0
CHG-FEAT: MASP A - COMPLTD
  3. If the calling name conversion facility feature is not on, shown by the CNCF = off entry in the rtrv-feat command output in step 1, turn the calling name conversion facility feature on by entering this command.

    chg-feat:cncf=on

    Note:

    Once the calling name conversion facility feature is turned on with thechg-feat command, it cannot be turned off.

    When the chg-feat has successfully completed, this message should appear. 

    rlghncxa03w 06-10-25 15:27:30 GMT EAGLE5 36.0.0

  4. Display the gateway screening stop action sets in the database with the rtrv-gws-actset command.

    This is an example of the possible output. 

    rlghncxa03w 06-10-25 15:28:30 GMT EAGLE5 36.0.0
ACT  ACT    ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT  ACT

6    cncfrd cncf rdct 
7    cpcfrd copy cncf rdct

GWS action set table is (7 of 16) 44% full

    If the cncf gateway screening stop action is not shown in the rtrv-gws-actset command output, perform the Configuring Gateway Screening Stop Action Sets procedure to create a new gateway screening stop action set containing the cncf gateway screening stop action, or change an existing gateway screening stop action set to contain the cncf gateway screening stop action.

  5. Display all allowed DPC screens in the database using the rtrv-scr-dpc command.

    The following is an example of the possible output. 

    rlghncxa03w 06-10-25 15:29:30 GMT EAGLE5 36.0.0
SCREEN = ALLOWED DPC
SR    REF  RULES
IEC   YES     2
WRD2  YES     1
WRD4  YES     9

    If the necessary screening reference name is shown in the rtrv-scr-dpc command output, make sure the screening data you wish to enter is not already in the database by entering the rtrv-scr-dpc command with the screening reference name. For example, enter the rtrv-scr-dpc:sr=iec command.

    The following is an example of the possible output. 

    rlghncxa03w 06-10-25 15:30:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED DPC
SR    NI       NC       NCM      NSFI    NSR/ACT

IEC     1      003      5        STOP    ------
  6. If the required screen is not in the database, perform the Adding an Allowed DPC Screen procedure to add the required allowed DPC screen.

    For this example, enter the screening information in Table 14-2.

    Table 14-2 Example Gateway Screening Allowed DPC Configuration Table for the CNCF Feature

    Screening Reference NI NC NCM NSFI ACTNAME*
    ls2 004 005 006 Stop CNCF
    ls13 001 002 003 Stop CPCNCF
    ls13 007 008 009 Stop CNCFRD
    * The value of the actname parameter is shown in the rtrv-gws-actset command output example shown in step 4.

    If you wish to change an existing allowed DPC screen, instead of adding a new allowed DPC screen, perform the Changing an Allowed DPC Screen procedure to change an existing allowed DPC screen. For this example, change the screens with the screening information in Table 14-2.

  7. Display all allowed SIO screens in the database using the rtrv-scr-sio command.

    The following is an example of the possible output. 

    rlghncxa03w 06-10-25 15:31:30 GMT EAGLE5 36.0.0
SCREEN = ALLOWED SIO
SR    REF  RULES
IEC   YES     2
WRD2  YES     1
WRD4  YES     9

    If the necessary screening reference name is shown in the rtrv-scr-sio command output, make sure the screening data you wish to enter is not already in the database by entering the rtrv-scr-sio command with the screening reference name. For example, enter the rtrv-scr-sio:sr=iec command.

    The following is an example of the possible output. 

    rlghncxa03w 06-10-25 15:32:30 GMT  EAGLE5 36.0.0
SCREEN = ALLOWED SIO

IEC   2    0&&3 4   --     --     STOP    ------
IEC   2    0&&2 1   *      *      DPC     WDB3
  8. If the required screen is not in the database, perform the Adding an Allowed SIO Screen procedure to add the required allowed SIO screen.

    For this example, enter the screening information in Table 14-3.

    Table 14-3 Example Gateway Screening Allowed SIO Configuration Table for the CNCF Feature

    Screening Reference NIC SI H0 H1 PRI NSFI NSR
    ls2 0 5 -- -- * dpc ls2
    ls13 0 5 -- -- * dpc ls13

    If you wish to change an existing allowed SIO screen, instead of adding a new allowed SIO screen, perform the Changing an Allowed SIO Screen procedure to change an existing allowed SIO screen. For this example, change the screens with the screening information in Table 14-3.

  9. Display all allowed OPC screens in the database using the rtrv-scr-opc command.

    The following is an example of the possible output. 

    rlghncxa03w 06-10-25 15:33:30 GMT EAGLE5 36.0.0
SCREEN = ALLOWED OPC
