Configuring Shelf-Controller Redundancy (APX 8000)

Configuring the APX 8000 for shelf-controller redundancy

Assigning the system IP address

To configure an APX 8000 that has redundant shelf controllers, you must map system IP settings to the unit’s soft IP interface. The soft IP interface is associated with the shelf controller that is currently primary.

Set the IP-Global profile’s System-IP-Addr parameter to the address of the soft IP interface. System-IP-Addr must not be set to a particular physical interface, such as the address of a shelf controllers. In a redundant shelf-controller system, the physical address of the primary controller changes according to which controller is currently primary, and the system IP address must be a single, unchanging address that always maps to the current primary controller.

Configuration of the soft IP interface address is described in the section “Defining the soft IP interface for fault tolerance” on page 2-5.

Assigning an Ethernet IP address

An APX 8000 creates an IP interface for the Ethernet port of each shelf controller. The IP-Interface profile index is based on each controller’s slot number. The left controller slot on the TAOS unit is number 41, and the right controller slot is 42.

To list the IP interfaces, use the Dir command, as follows:

admin> dir ip-interface

6 06/17/1999 03:06:00 { { any-shelf any-slot 0 } 0 }

1906/21/1999 23:54:02 { { shelf-1 left-controller 1 } 0 }

1906/25/1999 17:45:30 { { shelf-1 right-controller 1 } 0 }

The IP interface profile indicated by {{ shelf-1left-controller 1 } 0} is for the shelf controller in the first controller slot. The IP profile indicated by {{ shelf-1right-controller 1 } 0} is for the shelf controller in the second controller slot. The IP-Interface profile with the zero index {{ any-shelfany-slot 0 } 0} is reserved for the soft IP interface.

Examples of setting shelf-controller Ethernet IP address

Each shelf controller needs to be assigned an IP address. Following are examples that show how to configure the Ethernet IP addresses.

In the following example, the shelf controller in the left controller slot position (slot 41) is the primary controller. The primary controller is assigned the address 192.168.100.1/24:

admin> read ip-interface { { 1 41 1 } 0 } IP-INTERFACE/{ { shelf-1 left-controller 1 } 0 } read

admin> set ip-address = 192.168.100.1/24

admin> write

IP-INTERFACE/{ { shelf-1 left-controller 1 } 0 } written

The following commands assign the address 192.168.100.2/24 to the secondary (right) shelf controller. The commands must be performed on the primary (left) controller.

admin> read ip-interface { { 1 42 1 } 0 }

IP-INTERFACE/{ { shelf-1 right-controller 1 } 0 } read
