Changing the Weight and Threshold Values of MRN Entries

This procedure is used to change the weight and threshold values of entries in an existing Mated Relay Node (MRN) group or MRN set to new weight and threshold values. The weight and threshold values are changed using the chg-mrn command. This procedure can be performed only on MRN entries that have weight and thresholds assigned.

The following changes can be made in this procedure:

The individual weight values of the entries in the MRN group or MRN set with the wt/wt1/wt2/wt3/wt4 parameters.
The individual weight and relative cost values of the entries in the MRN group or MRN set with the wt/wt1/wt2/wt3/wt4, rc/rc1/rc2/rc3/rc4, and force=yes parameters.
The threshold values of the entities in the MRN group or MRN set that have the same relative cost value with the thr parameter. The new threshold value is assigned to the entities in the MRN group or MRN set that have the same relative cost value.
The weight values of the entities in the MRN group or MRN set that have the same relative cost value with the grpwt parameter. The new weight value is assigned to the entities in the MRN group or MRN set that have the same relative cost value.
The threshold and weight values of the entities in the MRN group or MRN set that have the same relative cost value with the thr and grpwt parameters. The new threshold and weight value is assigned to the entities in the MRN group or MRN set that have the same relative cost value.

The chg-mrn command can also be used to add point code entries to an existing MRN group or MRN set. This action is not covered in this procedure. If you wish to add point code entries to an existing MRN group or MRN set, perform Provisioning MRN Entries .

If the MRN entries being changed do not have weight and threshold values assigned to them, perform Changing the Relative Cost Values of MRN Entries.

If you wish to assign the same weight and threshold value to all the MRN entries in the MRN group or MRN set with the eswt and thr parameters, or to remove the weight and threshold values from all the MRN entries in the MRN group or MRN set with the eswt=none parameter, perform Changing MRN Entries with the ESWT Parameter. The eswt parameter cannot be used in this procedure.

If you wish to change the MAP set, MAP point code, and MAP SSN values assigned to an MRN set, using the mapset, mappc/mappca/mappci/mappcn/mappcn24, and mapssn parameters, perform Changing the MAPSET, MAP Point Code, and MAP SSN Values of MRN Entries. The mapset, mappc/mappca/mappci/mappcn/mappcn24, and mapssn parameters cannot be used in this procedure.

An MRN group or MRN set contains alternate point codes, up to 32, that are used for load sharing between multiple nodes when the EAGLE is performing intermediate global title translation. This load sharing is performed after intermediate global title translation is performed on the message. The point code in the message is changed to the selected point code in the MRN table. If the translated point code is not found in the MRN table, the translated point code in the message is not changed, the message is routed using route for the translated point code.

The chg-mrn command uses these parameters.

:pc/pca/pci/pcn/pcn24 – The point code in the message after intermediate global title translation has been performed.

:rc – The relative cost value of point code in the message

:pc1/pca1/pci1/pcn1/pcn241 – The first alternate point code value

:rc1 – The relative cost value of the first alternate point code

:pc2/pca2/pci2/pcn2/pcn242 – The second alternate point code value

:rc2 – The relative cost value of the second alternate point code

:pc3/pca3/pci3/pcn3/pcn243 – The third alternate point code value

:rc3 – The relative cost value of the third alternate point code

:pc4/pca4/pci4/pcn4/pcn244 – The fourth alternate point code value

:rc4 – The relative cost value of the fourth alternate point code

Note:

Refer to 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 a definition of the different formats that can be used for ITU national point codes.

:mrnset – The MRN set ID that the MRN is assigned to, shown in the rtrv-mrn output. MRN set IDs are shown only if the Flexible GTT Load Sharing feature is enabled. The mrnset parameter value cannot be changed in this procedure. For more information on the Flexible GTT Load Sharing feature, refer to Flexible GTT Load Sharing.

:grpwt – The group weight value. When this parameter is specified, the same weight value is assigned to all entries that have the same RC (relative cost) value in the MRN group or MRN set that contain the point code specified in the chg-mrn command. The value of this parameter is from 1 - 99.

:wt – The weight value assigned to the pc/pca/pci/pcn/pcn24 parameter value. The value of this parameter is from 1 - 99.

:wt1 – The weight value assigned to the pc1/pca1/pci1/pcn1/pcn241 parameter value. The value of this parameter is from 1 - 99.

:wt2 – The weight value assigned to the pc2/pca2/pci2/pcn2/pcn242 parameter value. The value of this parameter is from 1 - 99.

:wt3 – The weight value assigned to the pc3/pca3/pci3/pcn3/pcn243 parameter value. The value of this parameter is from 1 - 99.

:wt4 – The weight value assigned to the pc4/pca4/pci4/pcn4/pcn244 parameter value.

:thr – The in-service threshold assigned to the MRN group or MRN set. The in-service threshold is the minimum percentage (from 1 - 100) of weight that must be available for an RC group (a group of entries in the MRN group or MRN set that have the same RC value assigned) to be considered available to carry traffic. If the percentage of the available weight is less than the in-service threshold, then the entire RC group is considered unavailable for traffic. If the percentage of the available weight is equal to or greater than the in-service threshold, then the RC group is considered available, and traffic can be sent to any available entity in the RC group. The value of the thr parameter is assigned to all entries that have the same RC (relative cost) value in the MRN group or MRN set that contain the point code specified in the chg-mrn command.

:force=yes – This parameter must be specified if the rc/rc1/rc2/rc3/rc4 parameter is specified with the wt/wt1/wt2/wt3/wt4 parameter.

The relative cost parameter values (rc/rc1/rc2/rc3/rc4) determine how the global title translation load is to be shared among the alternate point codes. There are three types of load sharing that can be performed: dominant, load shared, or combined dominant/load shared.

All the point codes in a dominant MRN group or MRN set have different relative cost values. The translated point code in the message is the preferred point code that the message is routed on. The relative cost value assigned to the preferred point code does not have to be the lowest value in the MRN group or MRN set. All traffic is routed to the preferred point code, if it is available. If the preferred point code becomes unavailable, the traffic is routed to highest priority alternate point code that is available. When the preferred point code becomes available again, the traffic is then routed back to the preferred point code. For example, the MRN table contains the following entries.

PC             RC
   005-005-005    10
   006-001-001    20
   006-001-002    30
   006-001-003    40
   006-001-004    50
   006-001-005    60
   006-001-006    70
   006-001-007    80

If the preferred point code is 006-001-001 and it becomes unavailable, the traffic will be routed to point code 006-001-002.

All the point codes in a load shared MRN group have the same relative cost value. Traffic is shared equally between the point codes in this MRN group.

A combined dominant/load shared MRN group or MRN set is a combination of the dominant and load sharing MRN groups or MRN sets. A combined dominant/load shared MRN group or MRN set must contain a minimum of two entries with the same relative cost value and a minimum of one entry with a different relative cost value. Traffic is routed to the point code or point codes with the lowest relative cost value. If more than one point code has the lowest relative cost value, the traffic is shared between these point codes. If the point code or point codes with the lowest relative cost value become unavailable, traffic is routed to the the point code or point codes with the next higher relative cost value. If more than one point code has this relative cost value, the traffic is shared between these point codes. For example, the MRN table contains the following entries.

PC             RC
   005-005-005    10
   006-001-001    10
   006-001-002    10
   006-001-003    20
   006-001-004    20
   006-001-005    20
   006-001-006    20
   006-001-007    20

If the preferred point code is 006-001-001, the traffic is shared equally between point codes 005-005-005, 006-001-001, and 006-001-002. If point codes 005-005-005, 006-001-001, and 006-001-002 become unavailable, the traffic will be shared equally between point codes, 006-001-003, 006-001-004, 006-001-005, 006-001-006, and 006-001-007.

Specifying the grpwt or thr parameter with the chg-mrn command can be done when specifying only the pc/pca/pci/pcn/pcn24 parameter and without the alternate point code, relative cost (rc, rc1, rc2, rc3, rc4), and individual weight (wt, wt1, wt2, wt3, wt4) parameters.

The weight values assigned to the entires in the MRN group or MRN set are shown in the WT column in the rtrv-mrn output.

The in-service threshold values assigned to the entires in the MRN group or MRN set are shown in the THR column in the rtrv-mrn output.

The %WT column in the rtrv-mrn output shows the percentage of the traffic the particular entry in the entity set will handle.

The WT, %WT, and THR columns are shown in the rtrv-mrn output only if the Weighted GTT Load Sharing feature is enabled and turned on.

For more information on the Weighted GTT Load Sharing feature, refer to Weighted GTT Load Sharing.

Canceling the RTRV-MRN Command

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

Press the F9 function key on the keyboard at the terminal where the rtrv-mrn command was entered.
Enter the canc-cmd without the trm parameter at the terminal where the rtrv-mrn command was entered.
Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-mrn command was entered, from another terminal other that the terminal where the rtrv-mrn 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, refer to Commands User's Guide.

Display the mated relay node groups in the database using the rtrv-mrn command. This is an example of the possible output.

Change the attributes of the MRN group or MRN set using the chg-mrn command in one or more of the following steps.

To change only the in-service threshold value of the entires in the RC group - perform step 3.

To change the weight values of all entries in an RC group or to change the weight and in-service threshold values of the entries in the RC group - perform step 5.

To change the individual weight values of entries in an MRN group or MRN set - perform step 7.

To change the individual weight values and RC values of entries in an MRN group or MRN set - perform step 9.
The in-service threshold value is changed by specifying the thr parameter. The thr parameter can be specified by itself only if the MRN set or MRN group currently has weight values assigned.
The new thr value is assigned to all entries in the MRN group or MRN set that have the same RC value as the specified point code.

For this example, enter one of these commands.

To change the in-service threshold value of all entries in the MRN group that have the same RC value as the point code specified in this step without the Flexible GTT Load Sharing feature enabled, enter this command.

chg-mrn:pca=008-001-001:thr=50
To change the in-service threshold value of all entries in the MRN set that have the same RC value as the point code specified in this step with the Flexible GTT Load Sharing feature enabled, enter this command.

After this step has been performed, go to step 11.

An RC group is a group of point code entries that have the same RC value. This step is used to change the weight values of all the point codes in an MRN group or MRN set that have the same RC value to the same weight value using the chg-mrn command with the grpwt parameter.

A load shared MRN group or MRN set can be considered an RC group as all the entries in the group or set have the same RC value, but changing all the weight values in a load shared group or set to the same weight value can be accomplished by using the eswt parameter as described in Changing MRN Entries with the ESWT Parameter.

The in-service threshold value of the MRN group or MRN set can be changed by specifying the thr parameter with the chg-mrn command.

For this example, enter one of these commands.

To change only weight values of all entries in an RC group of the MRN group without the Flexible GTT Load Sharing feature enabled, enter this command.

chg-mrn:pca=009-005-005:grpwt=30
To change the weight and in-service threshold values of all entries in an RC group of the MRN group without the Flexible GTT Load Sharing feature enabled, enter this command.

chg-mrn:pca=009-005-005:grpwt=20:thr=30
To change only weight values of all entries in an RC group of the MRN set with the Flexible GTT Load Sharing feature enabled, enter this command.

chg-mrn:pca=005-005-005:grpwt=30:mrnset=1
To change the weight and in-service threshold values of all entries in an RC group of the MRN set with the Flexible GTT Load Sharing feature enabled, enter this command.
chg-mrn:pca=005-005-005:grpwt=20:thr=30:mrnset=1

If the MRN group or MRN set did not have weight and in-service threshold values assigned before this step was performed, and the thr parameter is not specified in this step, the in-service threshold value 1 (1%) is assigned to the entries.

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

Verify the changes using the rtrv-mrn command with the point code (pca/pci/pcn/pcn24 parameters) specified in step 5. If the mrnset parameter was specified in step 5, the mrnset parameter and value specified in step 5 must be specified with the rtrv-mrn command in this step.

For this example, enter these commands.

After this step has been performed, go to step 11.

Change the individual weight values and RC values of the MRN group or MRN set by entering the chg-mrn command with the point code parameters and their corresponding RC parameters (rc, rc1, rc2, rc3, and rc4) and weight parameters (wt, wt1, wt2, wt3, and wt4) parameters.
The thr parameter cannot be specified with the wt, wt1, wt2, wt3, and wt4 parameters.
Note:
If the RC values are changed so that the resulting MRN group of MRN set becomes a dominant MRN group or MRN set (the RC values are unique), the weight parameters can be specified with the chg-mrn command, but the the WT, %WT, and THR values are removed from the MRN group or MRN set and are not displayed in the rtrv-mrn output.
The following types of changes can be performed in this step:
- Weight and RC values for individual entries
- Weight values for some entries and the RC values for other entries
- Combinations of weight and RC values for individual entries and weight values for some entries and RC values for other entries.
The following examples show these types of changes.

The following MRN group is being changed.
