Release Notes for Cisco PDSN Release 5.2 in IOS Release 12.4(22)XR7
OL-23372-01
Migration to Cisco PDSN
2, 3 • Install the new SAMI card on 7600/720 that is to be used in a redundant configuration.
• In the existing Cisco PDSN Release 4.0, erase the existing configuration on all
processors and reload the Cisco PDSN.
• Configure the IOMEM size on all processors as 256 MB and save the configuration to
the NVRAM.
Note If you have set the IOMEM size as 64 MB, ensure that you configure the memory
lite command. The recommended memory size is, however, 256 MB.
• Upgrade both the SAMI blades to Cisco PDSN Release 5.2.
• Shut down the blade for configuration as standby (unit2).
• Enable autosynchronization on the active blade (unit1). Configure the PDSN on active
blade on processor 3. Keep unit2 as a standby in a redundant configuration. When
configuring redundancy, you must configure the Hot Standby Router Protocol (HSRP)
main interface before configuring InterProcessor Communication (IPC).
• Save the configuration on the active blade.
• Bring up unit2 with Cisco PDSN Release 5.2 image. Configurations are
autosynchronized from the active blade.
• Verify the output of the show redundancy state and show redundancy inter device
commands on both active and standby blades to confirm if redundancy is enabled. If the
output for one of the blades requires a reload to enable redundancy, reload that blade.
• Provision MS and PCFs to use the newly added Cisco PDSN Release 5.2-based PDSN
IP.
• Use the CDMA-1x IP address on the PDSN as controller or member IP when
provisioning.
• Provision the newly added PDSN with that of the HA to service MIP calls.
To minimize provisioning tasks, Cisco PDSN Release 5.2 reuses the IP address and routing
scheme used in one of the Cisco PDSN Release 4.0 processors.
