Configuring IPSP Before the Software Upgrade
Configuring IPSP requires changes to the primary HA (the HA on which the software upgrade is to occur), the
secondary HA (the HA to which subscribers sessions are to be directed), and the AAA server.
secondary HA (the HA to which subscribers sessions are to be directed), and the AAA server.
This section provides information and instructions for configuring IPSP before the software upgrade.
Important:
This section provides the minimum instruction set for configuring IPSP on the system. For more
information on commands that configure additional parameters and options, refer to the IPSP Configuration Mode
Commands chapter in the Command Line Interface Reference.

To enable the IP pool sharing during software upgrade:
Step 1
section.
Step 2
Configure an interface on the system for use by IPSP according to the instructions found in the Creating and
Configuring Ethernet Interfaces and Ports section of the System Administration Guide.
Configuring Ethernet Interfaces and Ports section of the System Administration Guide.
Step 3
Enable the IPSP on secondary HA by applying the example configuration in the
section.
Step 4
Perform the boot system priority and SPC/SMC card synchronization as described in Off-line Software Upgrade section
in the System Administration Guide.
in the System Administration Guide.
Step 5
Enable the IPSP on primary HA by applying the example configuration in the
section.
Step 6
Verify your ACL configuration by following the steps in the Verifying the IPSP Configuration section.
Step 7
Proceed for software upgrade as described in Off-line Software Upgrade section in the System Administration Guide.
Step 8
Save your configuration as described in the Saving Your Configuration chapter.
Configuring the AAA Server for IPSP
For subscriber session establishment, the AAA server provides the IP address of the HA that is to service the session.
This information exists in the 3GPP2_MIP_HA_Address RADIUS attribute configured for the subscriber.
This information exists in the 3GPP2_MIP_HA_Address RADIUS attribute configured for the subscriber.
Because the primary HA has been responsible for facilitating subscriber sessions, its IP address is the one configured via
this attribute. For IPSP however, the attribute configuration must change in order to direct sessions to the secondary HA.
this attribute. For IPSP however, the attribute configuration must change in order to direct sessions to the secondary HA.
To do this, reconfigure the 3GPP2_MIP_HA_Address RADIUS attribute for each subscriber on the AAA server with
the IP address of the secondary HA.

The precise instructions for performing this operation vary depending on the AAA server vendor. Refer to the
documentation for your AAA server for more information.
