Release Notes for Cisco PDSN Release 5.2 in IOS Release 12.4(22)XR7 Published: August 2010, OL-23372-01 Cisco IOS Release 12.4(22)XR7 is based on Cisco IOS Release 12.4, with enhancements to the Cisco Packet Data Serving Node (Cisco PDSN) feature. This Cisco PDSN Release 5.2 based on IOS Release 12.4(22)XR7 is optimized for the Cisco PDSN feature on the Cisco Service and Application Module for IP (SAMI) card on the Cisco 7600 Series Router.
Introduction Introduction Cisco PDSN is an IOS software feature that enables a SAMI card on a Cisco 7600 Series Router to function as a gateway between the wireless Radio Access Network (RAN) and the Internet. With Cisco PDSN enabled on a router, a stationary or roaming mobile user can access the Internet, a corporate intranet, or Wireless Application Protocol (WAP) services. Cisco PDSN supports both simple IP and mobile IP operations.
System Requirements Software Compatibility Cisco IOS Release 12.4(22)XR7 is developed on Cisco IOS Release 12.4 and supports the features included in Cisco IOS Release 12.4, with the addition of the Cisco PDSN feature. For information on the new and existing features, see Cisco PDSN Software Features in Release 12.4(22)XR7. MIBs Old Cisco MIBs will be replaced in a future release.
Migration to Cisco PDSN Migration to Cisco PDSN This section describes the migration paths and scenarios for Cisco PDSN Release 5.2: • Migration Path for Cisco PDSN, page 4 • Migration Scenarios for Cisco PDSN 5.2, page 5 • Migration Steps, page 8 Migration Path for Cisco PDSN Table 1 lists currently available Cisco PDSN releases and the migration path to the SAMI card. Table 1 Migration Path for Cisco PDSN Cisco PDSN Release 3.
Migration to Cisco PDSN Migration Scenarios for Cisco PDSN 5.2 Based on Table 1, there are many possible migration scenarios. This section focuses on those scenarios closest to existing customer deployments. You must determine the migration path based on your end-to-end deployment. Note • We recommend that you perform the migration during a maintenance window in your deployment. • You can also use this window for the following network redesign activities: – Redesigning IP address scheme.
Migration to Cisco PDSN Table 2 2 3 4 Migrations Scenarios for Cisco PDSN Release 5.2 (continued) • Non-SR • SR enabled • Non-clustering • Non-clustering • 7600 chassis • 7600 chassis • One blade with each processor acting as an individual Cisco PDSN • Two SAMI blades (in the same chassis) with a single Cisco PDSN at the blade level • Autosynchronization enabled • Erase existing configuration in all processors on active and standby blades. • After upgrading to Cisco PDSN Release 5.
Migration to Cisco PDSN Table 2 5 Migrations Scenarios for Cisco PDSN Release 5.2 (continued) • SR enabled (controller redundancy) • Clustering enabled • 7600 chassis • Running controller in one of the processors • Redundant SAMI blades (in the same chassis) • SR enabled • Clustering enabled • 7600 chassis • Can run both controller and collocated member • Redundant SAMI blades (in the same chassis) • 6 • Erase existing configuration in all processors on active and standby blades.
Migration to Cisco PDSN Migration Steps Migration to the Cisco PDSN Release 5.2 image is more than replacing Multi-processor WAN Application Module (MWAM) cards with SAMI modules. Ensure that you plan your migration such that migration activities have a minimal impact on an existing mobile subscriber’s service connections. Table 3 lists the migration tasks that are based on the scenarios established in Table 2. Table 3 Scenario 1 Migration Steps from Cisco PDSN 4.0 to 5.
Migration to Cisco PDSN Table 3 2, 3 Migration Steps from Cisco PDSN 4.0 to 5.2 (continued) • 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.
Migration to Cisco PDSN Table 3 4 Migration Steps from Cisco PDSN 4.0 to 5.2 (continued) • In SAMI cards with Cisco PDSN Release 4.0, erase the existing configuration on all processors and reload Cisco PDSN. If the blade includes Cisco PDSN members as part of the cluster, we recommend that you remove the PDSN member part before reloading. • Configure the IOMEM size on all processors as 256 MB and save the configuration to the NVRAM.
Migration to Cisco PDSN Table 3 5 Migration Steps from Cisco PDSN 4.0 to 5.2 (continued) • Install the new SAMI card on 7600/720 that is to be used in 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.
Upgrading to New Software Release Table 3 6 Migration Steps from Cisco PDSN 4.0 to 5.2 (continued) • 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 to 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.
Upgrading to New Software Release Determining the Software Version To determine the version of Cisco IOS software running on your router, log in to the router and enter the show version command in the EXEC mode: Router# show version Cisco IOS Software, SAMI Software (SAMI-C6IK9S-M), Experimental Version 12.4(20100227:034944) [jsomiram-CDMA_PDSN_V124_22_XR_R52_DTHO_26022010 102] Copyright (c) 1986-2010 by Cisco Systems, Inc.

Upgrading to New Software Release Upgrading the Supervisor Image To upgrade the Supervisor image: Step 1 Copy the SUP image to the disks (for example, disk0: / slavedisk0:). Step 2 Add the following command to the running-configuration boot system disk0:SUP-image-name. For example: boot system disk0:s72033-advipservicesk9_wan-mz.122-18.SXE3.bin Note To enable the image to reload, remove previously configured instances of this command.
