DCCA App
The DCCA APP tab is used in the DCCA Server Node test case to define the server emulator, mandatory and optional Diameter attributes, node behavior, the total amount of credit available to each MN, and the amount of credit granted per request.

Related Measurements
Measurements collected for the server node are reported on the Test Summary, DCCA Server, Diameter Server Node, and IP Instance report tabs.
General Settings
Preemptive Quota Allocation
When this box is checked, the server node will grant both time and volume credit units regardless of the type of unit requested by the client. You must also configure the Time Quota and Volume Quota to allocate both unit types.
Tcl Parameter: DiaSrvCcPreQuotaAllocEn
Reset Quota Allocation
When this box is checked, the defined quotas are reset for an MN account after the server node receives a terminate CCR for that account. If an initial CCR is subsequently received for the same MN, the total credit units defined will once again be available for allocation. Otherwise, only the units remaining after the last termination are available for a new request.
Tcl Parameter: DiaSrvCcResetQuotaEn
State Mode
Use the drop-down list to select the server node's Credit Control mode, when Vendor Variant is 1.
Options: Stateful (Currently, only one option is available.)
Default: Stateful
Tcl Variable: DiaSrvStateMachine
In Stateful mode, you can also set the session supervisor timer with Server TCC Time. Each session is individually timed, and the timer begins when the initial CCR for that session is received. The timer is reset whenever a CCR is received for that session. If you choose to set a validity time, this timer value should be set to at least twice the validity time to avoid unnecessary session termination due to transmission delays. Enter 0 to disable the timer.
Server TCC Time
Range: N/A
Default: 0
Tcl Variable: DiaSrvCcTccTime
CCF (Credit Control Failure) Handling
Use the drop-down list to provision the CCFH AVP. Clients are obligated to react in the method specified by the AVP when the Tx timer expires during a transaction.
Options:
-
Terminate (0) — The client must terminate the MN's session if it cannot communicate with the server.
-
Continue (1) — If failover is supported, the client should re-transmit the pending request to a secondary server if one is available; otherwise, the client may continue providing the service to the MN.
-
Retry-Terminate (2) — Similar to Continue, the client should try to move the session to a secondary server, but must terminate the MN's session if the CC session cannot be moved.
Default: Continue
Tcl Variable: DiaSrvCcCcfHandling
Enable/Force Message Level Result-Code Modification

CCR Count
The number of CCR messages received before the selected error is sent. The count is specific to each MN session. If you enter a 5, for example, the CCA sent in response to the fifth CCR received during an MN's session will include the selected Result-Code. If the session is terminated and then re-activated, the counter is reset. If an MN session is initiated and then terminated with less than five CCR messages, the error will never be sent during that session.
Range: 1 — 255
Default: 1

Result Code
The Result-Code AVP value to be sent. You can enter a value or click the ... button and use the drop-down list to select a pre-defined code. See Diameter Result Codes for code values and definitions.

MSCC Pane
In DDCA Node testing, the type of credit requested with the initial CCR and the actual credit granted by the server node that is reported by the Client with every update and termination CCR are defined in the Multiple Services Credit Control (MSCC) pane.
In any of the CCA responses, the server may include the Final-Unit-Indication AVP to notify the client that the credit granted represents the final units remaining in the account.

Use the drop-down list to select the maximum number of MSCC AVPs. Separate sub-tabs, labeled MSCC n, are displayed for each MSCC configuration.
Options: 1 — 10
Default: 1

AVP Database Size (bytes)
AVP Database size for each Mscc configuration is set to zero by default. This buffer is used only when the auto increment is selected in the AVP Template and the AVP Database size should be large enough for holding the AVP Data. If the auto increment is not selected, the AVP Database size may be 0.
DB Size (bytes) has been added to the VSA/AVP configuration window. This is the value the AVP Database estimator calculates that is required for the AVP Database size. It should be used when determining the size of the AVP Database Size in Bytes.

Apply Test Data File to AVP Configuration
This parameter is available only when Vendor Variant is None.
See Test Data Files for further explanation and sample files. If a sample is not found for the specific TDF, you can obtain a sample file from your Technical Support representative. You may also use the following options to select an existing TDF or create/edit TDF-CSV files (TDF-CSV Editor).
For most TDF Parameters used for Applying Parameters, each row in the file is the overridden value for a different “Session”, aka a different UE. But some TDFs are done in other dimensions, like Bearers, eNodeBs, Subscribers (2 per UE sometimes) or even Hosts, etc. Tooltips on the TDF Parameter:
Note that the “ID” is a unique ID. Please Provide the ID when reporting issues with a TDF. For TDFs that do not apply / override Parameters, but instead are just their own configuration or data or media files you won’t see TDF ID row details.
| TIP: When including large files, please be aware of memory limitations, since the TDF Editor shares memory with the Client. |
|
NOTE: The available TDF options vary. on the L3-7 | IPSec tab > IKE with RSA Settings you may only select the Certificate TDF from TAS (these are non-CSV TDFs). In addition, where applicable, any rules for defining TDFs are included in specific Test Cases. (For example, In MME Node test case, see MME Node - Provisioning TDF.) From the DMF Window, press Shift+Alt+A to display the Save DMF as Tcl window. Click the Save to File button to save as Tcl file. See additional details on Using the Tcl API.
