Removing MRN Entries

This procedure is used to remove an entry from an mated relay node (MRN) group or an entire MRN group from the database using the dlt-mrn command.

The dlt-mrn command uses these parameters.

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

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

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

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

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

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.

:all – Removes the entire MRN group or MRN set containing the point code specified by the pc/pca/pci/pcn/pcn24 parameter.

: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. If the Flexible GTT Load Sharing feature is enabled, the mrnset parameter must be specified with the dlt-mrn command.

:mapset - The MAP set ID assigned to the MRN set. This is the MAP set from which alternate routing indicator searches are performed. The mapset parameter is shown in the rtrv-mrn output only if the GTT Load Sharing with Alternate Routing Indicator feature is enabled. An MRN set or a point code in an MRN set cannot be removed if a MAP set is assigned to the MRN set.

If an entire MRN set is being removed in this procedure (with the all=yes parameter), or if a point code entry in an MRN set is being removed in this procedure, the reference to the MRN set specified in this procedure must be removed from any GTT or GTA entries before the point code can be removed from an MRN set, or before an entire MRN set can be removed.

Perform one of these procedures to remove the reference to the MRN set, depending on whether or not the EGTT feature is on. The status of the EGTT feature is shown in the rtrv-feat command output.

• If the EGTT feature is not on – Enter the rtrv-gtt command to verify the MRN set ID references. Perform the Changing a Global Title Translation procedure to remove the references to the MRN set.
• If the EGTT feature is on – Enter the rtrv-gta command to verify the MRN set ID references. Perform Changing Global Title Address Information to remove the references to the MRN set. The MRN set ID is not shown in the rtrv-ppsopt output.
• Any references to the MRN's point code and non-default MRN set ID in the rtrv-ppsopts output are removed in 9 of this procedure.
• Any references to the MRN's point code and non-default MRN set ID in the rtrv-gttact output are removed in 10 of this procedure.

Note:

If weight and in-service threshold values are assigned to a load shared or combined dominant/load shared MRN group or MRN set, and if by removing entries from this MRN group or MRN set, the MRN group or MRN set becomes a dominant MRN group or MRN set, all weight and threshold values are removed from the remaining entries in the MRN group or MRN set.

The mated relay node group being removed, or the point code value being removed from a MRN group must be in the database.

When removing point codes from an MRN group, the MRN group must contain the pc parameter value and at least one alternate point code value.

If the mrnset=dflt and all=yes parameters are specified with the dlt-mrn command, only the MRN group containing the point code value specified in the dlt-mrn command is removed from the default MRN set.

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.

1. Display the mated relay nodes in the database using the rtrv-mrn command.

   This is an example of the possible output.

   Note:

   If the Weighted GTT Load Sharing feature is not enabled and turned on, the WT, %WT, THR columns and values are not shown in the rtrv-mrn output.

   Continue the procedure by performing one of these steps.

   • If the MRNSET column is not shown in the rtrv-mrn output, then the Flexible GTT Load Sharing feature is not enabled. Continue the procedure with 11.
   • If only the MRNSET column is shown in the rtrv-mrn output, continue the procedure with 4.
   • If the MRNSET and MAPSET columns are shown in the rtrv-mrn output, continue the procedure by performing one of these steps.
     • If an entire MRN set is being removed, continue the procedure with 3.
     • If a point code entry is being removed from the MRN set, continue the procedure with 4.
     • If the MAP set entry is being removed from the MRN set, continue the procedure with 2.

       Note:

       If the MAPSET column contains dashes, then a MAP set is not assigned to the MRN set.
2. Remove the MAP set from the MRN set using the dlt-mrn command with the mrnset, mapset, and pc/pca/pci/pcn/pcn24 parameters and values shown in 1. For this example, enter this command.

   dlt-mrn:mrnset=1:mapset=5:pca=005-005-005

   This message should appear.

   If the rtrv-ppsopts output shows any entries that reference the MRN's point code and non-default MRN set ID, remove the reference using the chg-ppsopts command with the prepaid portability type (the PPT value) that contains the reference and either the pci=none or pcn=none parameters (depending on the type of point code the prepaid portability type contains).

   chg-ppsopts:ppt=8:pci=none

   This is an example of the possible output.

   Repeat this step for other entries shown in the rtrv-ppsopts output that contain the MRN's point code and non-default MRN set ID.

10. The MRN cannot be removed if the point code and non-default MRN set ID of the MRN is shown in the rtrv-gttact command output. Enter the rtrv-gttact command to verify that the MRN's point code and non-default MRN set ID is not shown in the rtrv-gttact output. For this example, enter this command.

    rtrv-gttact:pca=006-001-002:mrnset=1

    This is an example of the possible output.

    GTT-ACT  table is (3 of 2000) 1% full.

    If the rtrv-gttact output shows any entries that reference the MRN's point code and non-default MRN set ID, performing the Changing a GTT Action procedure to change the MRN set that is referenced in the GTT action to reference another MRN set or to reference no MRN set.

    Repeat this step for other entries shown in the rtrv-gttact output that contain the MRN's point code and non-default MRN set ID.

11. Remove the mated relay node from the MRN group or MRN set using the dlt-mrn command with a point code from the rtrv-mrn command output shown in 1 . For this example, enter this command.

    Note:

    If the MRNSET column is shown in the rtrv-mrn output in 1 , then the mrnset parameter must be specified with the dlt-mrn command. The mrnset parameter value must be the MRN set ID containing the point code specified in this step. If the MRNSET column is not shown in the rtrv-mrn output in 1 , the mrnset parameter cannot be specified with the dlt-mrn command.

    For this example, enter this command.

    dlt-mrn:pca=006-001-002:mrnset=1

    Note:

    If the entire MRN group or MRN set is not being removed in this step, the MRN group or MRN set must contain at least two entries after this step is performed.

    This message should appear.

    DLT-MRN:  MASP A - COMPLTD

    Note:

    If the MRNSET column is not shown in 1 and an entire MRN group is being removed from the database, enter the dlt-mrn command with the point code and the all=yes parameter. For this example, enter the dlt-mrn:pca=006-001-002:all=yes command.

    Note:

    If the MRNSET column is shown in 1 and an entire MRN set is being removed from the database, enter the dlt-mrn command with the point code, the mrnset parameter value containing a point code in the MRN set, and the all=yes parameter. For this example, enter the dlt-mrn:pca=006-001-002:mrnset=1:all=yes command. If the mrnset=dflt and all=yes parameters are specified with the dlt-mrn command, only the MRN group containing the point code value specified in the dlt-mrn command is removed from the default MRN set.

    Note:

    If weight and in-service threshold values are assigned to a load shared or combined dominant/load shared MRN group or MRN set, and if by removing entries from this MRN group or MRN set, the MRN group or MRN set becomes a dominant MRN group or MRN set, all weight and threshold values are removed from the remaining entries in the MRN group or MRN set.
12. Verify the changes using the rtrv-mrn command with the point code specified in 2 or 11.
    If the mrnset parameter was specified in 11 , the mrnset parameter and the mrnset parameter value specified in 11 must be specified in this step. For this example, enter this command.

    rtrv-mrn:pca=006-001-002:mrnset=1

    This message should appear.

    E4483 Cmd Rej: PC does not exist in specified MRNSET

    Note:

    When an entire MRN group is removed from the default MRN set, this message, E4483, will appear when the rtrv-mrn command is specified with the mrnset=dflt and the point code value specified in 11.

    If an entire MRN set was removed in 11 , the following message appears when this step is performed.

    E4480 Cmd Rej: Specified MRNSET does not exist

    If the Flexible GTT Load Sharing feature is not enabled, the mrnset parameter cannot be specified with the rtrv-mrn command. When this step is performed (without the Flexible GTT Load Sharing feature enabled and without the mrnset parameter), the following message appears.

    E2849 Cmd Rej: PC must already exist in the MRN table

    If the MAP set was removed from the MRN set in 2, enter the rtrv-mrn command with the mrnset and point code parameters and values specified in 2. For this example, enter this command.

    rtrv-mrn:mrnset=1:pca=005-005-005

    This is an example of the possible output.
