Diameter Command Codes

The Command Code is one of the parameters contained in a Diameter Message. In the Command Codes configuration section, you can define the Command Code values that can be used in Peer Routing Rules and Application Routing Rules.

You can perform these tasks on an Active System OAM (SOAM).

An (Extended) Command Code is a command code extension that includes the following attributes:

• Command Code (parent Command Code)
• AVP Code
• AVP Data value

This broadens the definition of Diameter Command Codes to include an additional application-specific single Diameter or 3GPP AVP content per Command Code. A format example might be 272.416.1 = CCR/CCA-I.

Note:

All (E)CCs are predefined and preloaded into the configuration.

(E)CCs are synonymous with CCs, as a GUI element and as a reference for other managed objects. After (E)CCs are configured on the Command Codes page, they are listed as choices on the Inserting Rule for Application Route Table, Inserting Rule for Peer Route Table, Transaction Configuration Sets [Insert], and Message Priority Configuration Sets [Insert] pages.

Note:

A parent CC or Base CC is a Command Code without AVP code and Data extensions. All (E)CCs are extensions of any of the configured base command codes.

On the Diameter > Configuration > Command Codes page, you can perform the following actions:

• Filter the list of Command Codes to display only the desired Command Codes.

• Sort the list entries in ascending or descending order by Command Code or Command Code Name by clicking the column heading. By default, the list is sorted by Command Code in ascending numerical order. When comparing two cell values in the Command Code column for sorting, the Command Code part of the cell values are compared followed by AVP Code part of the cell values followed by AVP Value part of the cell values. If the AVP Code and AVP Value part is missing for a cell value, it is considered as zero for the comparison.

• Click Insert.

  On the Diameter > Configuration > Command Codes [Insert] page, you can add a new Command Code. See Adding a Command Code. If the maximum number of Command Codes (1000) already exists in the system, then the Diameter > Configuration > Command Codes [Insert] page does not appear and an error message displays.

• Select a Command Code in the list and click Edit.

  On the Diameter > Configuration > Command Codes [Edit] page, you can edit the selected Command Code. See Editing a Command Code.

• Select an Command Code in the list and click Delete to remove the selected Command Code. See Deleting a Command Code.

  Note:

  Delete is disabled for (E)CCs.
