Use the Meta Variable Dynamic window to view and edit the contents of the metaVariableDynamic table. In SBC SWe N:1 or cloud-based deployments, metadata configures values related to the SBC interfaces such as IP addresses and gateways. This information initially comes during instantiation from the metadata found in Heat templates or from configuration drives.

This table enables you to define additional metavariables to add to the metadata in an existing SBC deployment. The metavariable values in the table become available to the SBC instance without having to rebuild it. For example, you can add the metavariable values needed to configure an additional SIP signaling port in a deployed SBC instance. Refer to Using Dynamic Metavariables to Add a SIP Signaling Port.

Note

The table is not intended to make changes to existing configuration.  You cannot add metavariables to the table to override values that were already defined during instantiation.

View the MetaVariableDynamic Table

From the SBC main window, go to All > System > Meta Variable Dynamic. The Meta Variable Dynamic window opens.
