Use this procedure to redirect states when you need to perform a software upgrade on an MRA server or remove an MRA server.
To change the redirect state of an MRA server:
In the MRA section of the navigation bar, click Configuration.
Select an MRA.
The MRA Administration page displays information about the selected MRA.
Select the MRA tab.
Click Advanced.
Click Modify to edit the Service Overrides table.
In the Service Overrides section, click Add.
The Add Configuration Key Value dialogue opens.
Enter DIAMETERDRA.RedirectState.
This service override indicates the redirect state of the MRA server.
Enter the redirect state in the Value field. The valid options are:
Changing this variable to NORMAL will stop the release process.
Note: In all redirect states, the MRA servers continue to handle DRMA traffic and process traffic normally for subscribers with existing bindings.
NORMAL (default)
The MRA server redirects CCR-I messages only when the DRMA link between the clustered MRA servers is down and the subscriber does not have an existing binding on the MRA server that first receives the CCR-I.
ALWAYS
The MRA server always redirects CCR-I messages to the MRA it is clustered with for subscribers that do not have existing bindings, whether the DRMA link is active or not. An MRA server in this state is not able to create new bindings.
NEVER
The MRA server never redirects messages to the MRA it is clustered to, whether the DRMA link is active.
(Optional) Enter information for this configuration in the Comments field.
