    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.

    Description

    Configure the high availability (HA) options for the aggregated multiservices (AMS) interface.

    The following modes of high availability are supported with AMS:

    • One-to-one (1:1) mobile control plane redundancy—In this case, one active multiservices PIC is backed up by one standby multiservices PIC in hot standby mode.
    • Many-to-one (N:1) high availability for service applications (application-level gateway [ALG], Network Address Translation [NAT], and stateful firewall)—In this case, one multiservices PIC is the backup (in hot standby mode) for one or more (N) active multiservices PICs. If one of the active multiservices PICs goes down, then the backup replaces it as the active multiservices PIC. When the failed PIC comes back online, it becomes the new backup. This is called floating backup mode.

    Note: In hot standby mode, the operational state of subscribers anchored on the active multiservices PIC (or PICs) is actively synchronized with the standby multiservices PIC.

    The remaining statements are explained separately.
