This command allows you to configure the refresh interval for a UIDH key.

configure > context context_name > uidh-server uidh_server_name
Entering the above command sequence results in the following prompt:
Deletes the refresh interval parameter from the UIDH server configuration.
Configures the default interval value in the UIDH server configuration.
The refresh interval time is configured in hours and is an integer ranging from 8 to 168 hours. The default interval value
is 8 hours.
Use this command to configure the refresh interval in the UIDH sever configuration.
When a session is attached to P-GW, the P-GW queries the UIDH server. If there is no response from the UIDH server, the UIDH
service is not enabled for this session. If there is a Whitelisted subscriber, the UIDH server sends the UIDH string to P-GW.
The P-GW queries the UIDH string after the refresh interval.
On querying, if P-GW does not receive a response, it uses the existing key and sends another request after the refresh interval.
If P-GW receives a response with an empty string – subscriber moving from OPT-IN to OPT-OUT, it does not perform a key refresh
and UIDH insertion is disabled until the subscriber re-attaches.
Any status change of a subscriber from OPT-OUT to OPT-IN is applied only on subscriber attach. However, the status changes
from OPT-IN to OPT-OUT is applied only after refresh interval.
When a subscriber moves to the OPT-OUT status, it is indicated with the following response: 200 OK Blank Response. This indicates
that the request has been processed successfully at the UIDH server and that the subscriber has opted out.
In case of UIDH service failure, either because of a failure in service or because of failure in connection to the UIDH server,
the P-GW continues to process the session without inserting the UIDH hash value.
The following command sets the refresh interval in the UIDH server as 6 hours::
