Release Notes for Cisco PDSN Release 5.1 in IOS Release 12.4(22)XR2
Published: November 06, 2009, OL-20783-01
Cisco IOS Release 12.4(22)XR2 is based on Cisco IOS Release 12.4, with enhancements to the Cisco Packet Data Serving Node (Cisco PDSN) feature. This Cisco PDSN Release 5.1 based on IOS Release 12.4(22)XR2 is optimized for the Cisco PDSN feature on the Cisco Service and Application Module for IP (SAMI) card on the Cisco 7600 Series Router.
These release notes include important information and caveats for the Cisco PDSN software feature provided by the Cisco IOS 12.4(22)XR2 for the Cisco 7600 Series Router platform.
This release note describes:
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.
This section describes the system requirements for running Cisco IOS Release 12.4(22)XR2:
To install Cisco PDSN Release 5.1 that supports the SAMI card on the Cisco 7600 Series Router, ensure that you meet the following memory requirements:
•Platform: Cisco 7600 Series Router
•Software/Feature Set: PDSN
•Image Name: 12.4(22)XR1 - c7svcsami-c6ik9s-mz.124.22.XR (This file is a bundled image.)
–Flash: 256 MB
–DRAM: 2048 MB
•Runs from: RAM
Cisco IOS Release 12.4(22)XR2 is optimized for the SAMI card on the Cisco 7600 Series Router.
You can use the Hardware-Software Compatibility Matrix tool to search for hardware components that are supported on a Cisco platform and an IOS release.
Note You must have a valid Cisco.com account to log in to this tool: http://www.cisco.com/cgi-bin/front.x/Support/HWSWmatrix/hwswmatrix.cgi
Cisco IOS Release 12.4(22)XR2 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)XR21.
Old Cisco MIBs will be replaced in a future release. Currently, OLD-CISCO-* MIBs have been converted to more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update deprecated MIBs, to the replacement MIBs as shown in Table 1.
Migration to Cisco PDSN
This section describes the migration paths and scenarios for Cisco PDSN Release 5.1:
Migration Path for Cisco PDSN
Table 2 lists currently available Cisco PDSN releases and the migration path to the SAMI card.
Migration Scenarios for Cisco PDSN 5.1
Based on Table 2, 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.
–Configuring the routing protocols.
–Configuring network connectivity between Cisco PDSN and the Home Agent (HA).
–Configuring application connectivity between Cisco PDSN and AAA servers.
–Configuring routing on the new SAMI Cisco PDSN or the HA.
Note For all these migration plans, both hardware and software configurations have significant changes. This requires prudent operation planning and network redesign. The Migration Steps section describes the possible migration steps to minimize both network reconfiguration and service disruption.
Table 3 lists the most common migration scenarios.
Migration to the Cisco PDSN Release 5.1 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.
Upgrading to New Software Release
The following sections describe how to determine the existing software version and how to upgrade your Cisco PDSN:
For information on upgrading to a new software release, see the product bulletin Cisco IOS Software Upgrade Ordering Instructions, located at:

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.
Step 3 Run the write memory command to save the running-configuration on the active and standby SUP.
Step 4 Run the reload command on the active SUP.
Both active and standby SUP reload simultaneously and come up with the SXE3-based image.
Note Running the reload command on the active SUP causes both the active and standby Supervisors to reload simultaneously, causing some downtime during the upgrade process.
Upgrading the SAMI Software
To upgrade an Cisco PDSN image on the SAMI card, follow the directions at:
Changing Configuration on Cisco PDSN in a Live Network
To change the working configuration on a Cisco PDSN in a live environment:
Step 1 Bring the standby Cisco PDSN out of service.
For example, to isolate the standby Cisco PDSN from the session redundancy setup, you must run the no cdma pdsn redundancy command.7600a-Stdy(config)# no cdma pdsn redundancy
Step 2 Run the write memory command to save the configuration.
Step 3 Make the necessary configuration changes on the standby Cisco PDSN, and save the configuration.
Step 4 Run the cdma pdsn redundancy command again and save the configuration.
Step 5 Issue the reload command to bring the standby Cisco PDSN back into the session redundancy setup with the changed configuration. Verify if the processor comes back in the SR setup using the following show commands:7600a-Stdy# show standby briefP indicates configured to preempt.|Interface Grp Prio P State Active Standby Virtual IPGi0/0.101 300 110 Standby 188.8.131.52 local 184.108.40.2067600a-Stdy# show cdma pdsn redundancyCDMA PDSN Redundancy is enabledCDMA PDSN Session Redundancy system statusPDSN state = STANDBY HOTPDSN-peer state = ACTIVECDMA PDSN Session Redundancy StatisticsLast clearing of cumulative counters neverTotal CurrentSynced from active ConnectedSessions 15 15SIP Flows 15 15MIP Flows 0 0PMIP Flows 0 07600a-Stdy# show redundancy inter-deviceRedundancy inter-device state: RF_INTERDEV_STATE_STDBYScheme: StandbyGroupname: pdsn-rp-sr1 Group State: StandbyPeer present: RF_INTERDEV_PEER_COMMSecurity: Not configured7600a-Stdy# show redundancy statesmy state = 8 -STANDBY HOTpeer state = 13 -ACTIVEMode = DuplexUnit ID = 0Split Mode = DisabledManual Swact = EnabledCommunications = Upclient count = 9client_notification_TMR = 30000 millisecondsRF debug mask = 0x07600a-Stdy#
Step 6 Configure the standby Cisco PDSN to take over as active by reloading the current active Cisco PDSN.
Caution Before proceeding with the configuration changes, we recommend that you disable the HSRP preemption configuration on the active and standby PDSN.
Because of a change of configuration following this step, an outage may occur on existing calls on the active PDSN (which is now being taken out of service) when synchronized with new active units.
Note For Cisco PDSN SR to work properly, ensure that configurations on the active and standby Cisco PDSNs are identical.
Cisco PDSN Software Features in Release 12.4(22)XR2
Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, the purchaser or user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to email@example.com.
