Configuring Warm Standby for Services Interfaces

You can configure an N:1 warm standby option for MS-MPCs, MS-MICs, and MX-SPC3s by creating multiple aggregated multiservices (AMS) interfaces, each of which contains the service interface you want to backup and the service interface that acts as the backup. The same backup service interface can be used in all these AMS interfaces. Starting in Junos OS Release 19.3R2, the N:1 warm standby option is supported on the MX-SPC3.

To configure warm standby for services interfaces:

  1. Create an AMS interface.

    The variable N is a unique number, such as 0 or 1.

  2. Specify the primary service interface that you want to backup.

    The variable a is the FPC slot number and b is the PIC slot number for the primary service interface.

  3. Specify the secondary service interface, which backs up the primary interface.

    The variable a is the FPC slot number and b is the PIC slot number for the secondary service interface.

  4. Repeat Steps 1 through 3 to create an AMS interface for each service interface that you want to backup. You can use the same secondary service interface in each AMS interface.
