Configuring Shelf-Controller Redundancy (APX 8000)

Configuring the APX 8000 for shelf-controller redundancy

Configuring shelf-controller redundancy

When setting up shelf-controller redundancy, you might need to configure the following profiles:

•Physical interface profiles (such as IP-Interface, Serial, Ethernet, Ether-Info)

•Redundancy profile

Note: Lucent recommends that you modify profiles on the primary controller only. Modified profiles are sent to the secondary controller.

During profile configuration, the write and delete command-line interface commands check for permission before allowing you to write or delete any profile. Profile writes or deletes are not allowed on the secondary controller, but you can force implementation of the commands if you use the -fcommand option. When you use -f, a warning message alerts you that a profile written on the secondary might be overwritten by a transfer from the primary controller.

Physical interface profiles

The profiles of the physical interfaces, such as IP-Interface, Serial, Ethernet, and Ether-Info, are indexed by each controller’s slot number. The left shelf-controller slot is 41, and the right shelf-controller slot is 42.

For example, to read the IP Interface profile for the shelf controller in the left controller slot, enter the following command:

admin> read ip-interface { { 1 41 1 } 0 }

The APX 8000 has only one shelf, which is identified as shelf-1.

Redundancy profile

The Redundancy profile maintains each controller’s configuration information (context). The shelf controllers exchange context information during heartbeat communications and use it to track each other’s status. The context information for each controller is stored as an array and is identified as Context[1] or Context[2].

Configuration of the Redundancy profile primarily involves the following subprofiles and parameters:

•Primary-Preference is a parameter that allows the user to indicate a preference for electing a controller as primary.

•Context is a subprofile that contains context subprofiles for both controllers, Context[1] and Context[2].

•Context [N] is a subprofile that contains the context information for an individual controller (Context[1] or Context[2]).

Note: Configuration of the Redundancy profile parameters must be done only on the primary controller. Profiles written on the secondary controller can be overwritten.

Use the read and write command-line interface commands to make Redundancy the working profile and list the Redundancy profile contents.
