Setting the Threshold for Reporting Gateway Screening Activity

This procedure is used to set the threshold for reporting these gateway screening activities using the set-gtwy-acthresh command.

• The threshold for MSUs received on a gateway link set.
• The threshold for MSUs rejected on a gateway link set because of screening.

These thresholds are set on a linkset basis. These gateway screening activities are reported only if the threshold is set and only if the threshold is reached.

The set-gtwy-acthresh command uses these parameters.

:intrvl – The examination period, in minutes, during which the gateway screening activity thresholds are to be tested.

:lsn – The name of the linkset that the thresholds are assigned to.

:recv – The threshold for MSUs received on the gateway link set.

:rej – The threshold for MSUs rejected on the gateway link set because of screening.

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.

2. Display the current linkset configuration using the rtrv-ls command.

   Link set table is ( 9 of 1024)  1% full
   

   If the GWSA value of the linkset is no, shown in the GWSACT column of the rtrv-ls output, perform the "Changing an SS7 Linkset" procedure in Database Administration - SS7 User's Guide to change the GWSA value of the linkset. Continue the procedure with 3.

   If the GWSA value of the linkset is yes, continue the procedure with 3.

3. Set the gateway screening thresholds for a linkset using the set-gtwy-acthresh command.

   For this example, enter this command.

   set-gtwy-acthresh:lsn=lsa2:intrvl=20:rej=30:recv=2500

   When this command has successfully completed, a message similar to the following should appear.

   rlghncxa03w 06-10-25 15:29:30 GMT EAGLE5 36.0.0
   SET-GTWY-TRHSHLD: MASP A - COMPLTD
   

4. Verify the changes using the rtrv-gtwy-acthresh command with the linkset name specified in step 3.

   For this example, enter this command.

   rtrv-gtwy-acthresh:lsn=lsa2

   The following is an example of the possible output.

   rlghncxa03w 06-10-25 15:30:30 GMT EAGLE5 36.0.0
   LSN      REJ     RECV   INTRVL
   LSA2     30      2500   20
   

5. Backup the new changes using the chg-db:action=backup:dest=fixed command.

   The following 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.
