    Mobility Maintenance Mode Overview

    Junos OS maintenance mode for the MobileNext Broadband Gateway allows you to take certain network functionality offline to perform specific maintenance tasks without disrupting service. When access point names, gateways, subscribers, and the like need maintenance, entering maintenance mode prevents these mobility elements from accepting new requests. You have the option of allowing all existing services to complete, or clear them. When ready, proceed with critical maintenance functions with a minimum of service disruption. Subscribers who attempt to access a gateway that is active in maintenance mode are prompted with a notice that the service is not supported.

    You can make the following changes in maintenance mode:

    • Delete or modify the addresses of certain GPRS tunneling protocol (GTP) interfaces.
    • Delete or change the type of an access point name (APN).
    • Change mobile interface configuration parameters.
    • Change a mobile interface for an APN.
    • Delete a charging profile.
    • Delete or modify a charging data record (CDR) profile or CDR type.
    • Delete or modify a transport profile.
    • Delete or modify a trigger profile.
    • Delete a mobile pool or modify its parameters.

    These maintenance tasks are discussed in this topic. You can perform all other maintenance tasks outside of maintenance mode.

    Notice that the maintenance mode procedures listed do not include adding elements. This is logical-new gateways, APNs, and such carry no traffic and thus do not need to be gracefully halted. However, you can create new mobility network elements in maintenance mode as an environment in which to test configurations before deploying them.
