Changing the SCCP Alarm Thresholds

This procedure is used to change the SCCP alarm thresholds using the chg-th-alm command and these parameters.

:sccptpscap – The percentage for the SCCP load capacity (TPS) threshold alarm, from 0 to 100 and is shown in the SCCP TPS Threshold field of the rtrv-th-alm output and in the System TPS Alarm Threshold field in the rept-stat-sccp output. The system default value is 80. When this threshold is exceeded, UAM 330 is generated.

:sccpcalcmthd – The calculation method used for determining if the SCCP load capacity (TPS) threshold alarm level has been exceeded. This parameter contains these values:

• N – All in-service normal cards are used in the SCCP load capacity (TPS) threshold alarm level calculation.

• NPLUS1 – All in-service normal cards minus one of the in-service normal card with the highest TPS capacity are used in the SCCP load capacity (TPS) threshold alarm level calculation.

The system default value is N.

The value of this parameter is shown in the SCCP Calculation Method field of the rtrv-th-alm output and in the System SCCP Capacity Calc. Method field in the rept-stat-sccp output.

The service modules that can be used are SMs and E5-SM4Gs. Each type of service module supports a certain number of transactions per second (TPS), SMs - 1700, and E5-SM4G - 1700 or 5000 if the E5-SM4G Throughput Capacity feature is enabled. If the sccpcalcmthd=n parameter is specified, the value in the System SCCP Capacity Calc. Method field in the rept-stat-sccp output is the sum of the TPS ratings of all the in-service normal service modules, shown with the entry IS-NR in the PST column in the rept-stat-sccp output.

If the sccpcalcmthd=nplus1 parameter is specified, the value in the System SCCP Capacity Calc. Method field in the rept-stat-sccp output is the sum of the TPS ratings of all the in-service normal service modules, shown with the entry IS-NR in the PST column in the rept-stat-sccp output, minus the TPS rating of the highest rated in-service normal card. If the EAGLE contains only SMs, or only E5-SM4Gs as service modules, then the TPS rating of one of the SM or SLIC cards, as applicable, is subtracted from the sum of the TPS ratings of all the in-service normal service modules. If the EAGLE contains SMs or SLIC, then the TPS rating of one of the cards is subtracted from the sum of the TPS ratings of all the in-service normal service modules.

:gttservl1 – The percentage of the SCCP GTT service errors, shown in the FAIL RATIO column for the GTT row of the TOTAL SERVICE STATISTICS: section of the rept-stat-sccp output, from 1 to 100, that when exceeded, generates major alarm UAM 0452. The system default value is 10.

:gttservl2 – The percentage of the SCCP GTT service errors, shown in the FAIL RATIO column for the GTT row of the TOTAL SERVICE STATISTICS: section of the rept-stat-sccp output, from 1 to 100, that when exceeded, generates critical alarm UAM 0453. The system default value is 20.

Note:

After the chg-th-alm command is performed, the gttservl2 parameter value must be greater than the gttservl1 parameter value.

:nongttservl1 – The percentage of the SCCP non-GTT service errors (for example, GPORT, GFLEX, EIR, etc.), shown in the FAIL RATIO column for the rows other than GTT in the TOTAL SERVICE STATISTICS: section of the rept-stat-sccp output, from 1 to 100, that when exceeded, generates major alarm UAM 0452. The system default value is 10.

:nongttservl2 – The percentage of the SCCP non-GTT service errors (for example, GPORT, GFLEX, EIR, etc.), shown in the FAIL RATIO column for the rows other than GTT in the TOTAL SERVICE STATISTICS: section of the rept-stat-sccp output, from 1 to 100, that when exceeded, generates critical alarm UAM 0453. The system default value is 20.

Note:

After the chg-th-alm command is performed, the nongttservl2 parameter value must be greater than the nongttservl1 parameter value.

:sccpthlv1intvl - The number of minutes, from 0 to 1440, during which the SCCP threshold level 1 alarm (UAM 0452) cannot be raised more than once. The system default value is 0.

:sccpthlv2intvl - The number of minutes, from 0 to 1440, during which the SCCP threshold level 2 alarm (UAM 0453) cannot be raised more than once. The system default value is 0.

Note:

After the chg-th-alm command is performed, the sccpthlv2intvl parameter value must be greater than the sccpthlv1intvl parameter value.

For more information on these alarms, refer to Unsolicited Alarm and Information Messages Reference.

The chg-th-alm command contains other optional parameters. These parameters are not shown here because they are not necessary to provision the SCCP alarm thresholds. These parameters are explained in more detail in Commands User's Guide.

1. Display the current SCCP alarm thresholds in the database by entering thertrv-th-alm command. This is an example of the possible output.

   rlghncxa03w 08-03-28 09:12:36 GMT EAGLE5 38.0.0
   SCCP TPS Threshold:                  80%
   SCCP Calculation Method:             N
   GTT SCCP Service Alarm Level 1:      10%
   GTT SCCP Service Alarm Level 2:      20%
   Non-GTT SCCP Service Alarm Level 1:  10%
   Non-GTT SCCP Service Alarm Level 2:  20%
   SCCP Service Alarm Level 1 Interval: 0
   SCCP Service Alarm Level 2 Interval: 0
   Command Executed

   Note:

   The rtrv-th-alm command output contains other fields that are not used in this procedure. If you wish to see all the fields displayed by the rtrv-th-alm command, refer to the rtrv-th-alm command description in Commands User's Guide.
2. Change the SCCP alarm thresholds by entering the chg-th-alm command with at least one of the SCCP alarm threshold parameters.

   If a SCCP alarm threshold parameter is not specified with the chg-th-alm command, that parameter value will not be changed. The system default values for the SCCP alarm threshold parameters are:

   • sccptpscap – 80
   • sccpcalcmthd – n
   • gttservl1 – 10
   • gttservl2 – 20
   • nongttservl1 – 10
   • nongttservl2 – 20
   • sccpthlv1intvl – 10
   • sccpthlv2intvl – 20.

   Note:

   After the chg-th-alm command is performed, the gttservl2 parameter value must be greater than the gttservl1 parameter value, the nongttservl2 parameter value must be greater than the nongttservl1 parameter value, and the sccpthlv2intvl parameter value must be greater than the sccpthlv1intvl parameter value.

   For this example, enter this command.

   chg-th-alm:sccptpscap=70:gttservl1=70:gttservl2=80:nongttservl1=30:nongttservl2=40 :sccpthlv1intvl=120:sccpthlv2intvl=240

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

   CHG-TH-ALM: MASP A - COMPLTD

3. Verify the changes using the rtrv-th-alm command. This is an example of the possible output.

   rlghncxa03w 08-3-28 09:12:36 GMT EAGLE5 38.0.0

   GTT SCCP Service Alarm Level 2:      80%
   Non-GTT SCCP Service Alarm Level 1:  30%
   Non-GTT SCCP Service Alarm Level 2:  40%
   SCCP Service Alarm Level 1 Interval: 120
   SCCP Service Alarm Level 2 Interval: 240
   Command Executed

   Note:

   The rtrv-th-alm command output contains other fields that are not used in this procedure. If you wish to see all the fields displayed by the rtrv-th-alm command, refer to the rtrv-th-alm command description in Commands User's Guide.
4. 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.
