Migration Scenarios for Cisco PDSN 5.5

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.


 


NoteFor all these migration plans, both hardware and software configurations have significant changes. This requires prudent operation planning and network redesign. The 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 4 lists the migration tasks that are based on the scenarios established in Table 3 .

 

Table 4 Migration Steps from Cisco PDSN 4.0 to 5.5

Scenario
Migration Steps

1

  • In SAMI cards with the Cisco PDSN Release 4.0 image, erase configuration on all processors and reload Cisco PDSN.
  • Configure the I/O memory (IOMEM) 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 to Cisco PDSN Release 5.5 and reconfigure the Cisco PDSN configuration on processor 3.
  • Provision MS and PCFs to use the newly added Cisco PDSN Release 5.5-based PDSN IP.
  • Provision the newly added PDSN with the HA to service MIP calls.

To minimize provisioning tasks, Cisco PDSN Release 5.5 reuses the IP address and routing scheme used in one of the Cisco PDSN Release 4.0 processors.

1. MS = Mobile Station.
2. PCF = Packet Control Function.

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 5.5.
  • 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 5.5 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 5.5-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 5.5 reuses the IP address and routing scheme used in one of the Cisco PDSN Release 4.0 processors.

4

  • 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.

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 to Cisco PDSN Release 5.5 and reconfigure the PDSN on processor 3.
  • You can configure the Cisco PDSN as both controller and collocated member. Cisco PDSN Release 5.5 interoperates with Cisco PDSN Release 3.0 or 4.0 controller or member.
  • Provision MS and PCFs to use the newly added Cisco PDSN Release 5.5-based PDSN IP.
  • Use the CDMA-1x IP address on the PDSN as controller or member IP when provisioning.
  • Provision newly added PDSN with that of the HA to service MIP calls.

To minimize provisioning tasks, Cisco PDSN Release 5.5 reuses the IP address and routing scheme used in one of the Cisco PDSN Release 4.0 processors.

5

  • 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. The recommended memory size is, however, 256 MB.


  • Upgrade both the SAMI blades to Cisco PDSN Release 5.5.
  • 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 5.5 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 5.5-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.
  • You can configure the Cisco PDSN to act as controller and collocated member.

In the case of a collocated member, ensure that you enable session redundancy, so that the standby is synchronized with sessions handled by the collocated member.

For an active controller to synchronize the information with the standby controller, ensure that all remote members connect to the HSRP main interface of the controller.

If the member IP is configured, ensure that it is the same as the CDMA -1x interface IP address.

6

  • 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.


  • Upgrade both the SAMI blades to Cisco PDSN Release 5.5.
  • Reconfigure the Cisco PDSN and enable inter-chassis HSRP redundancy as in Cisco PDSN Release 4.0.
  • Provision MS and PCFs to use the newly added Cisco PDSN Release 5.5-based PDSN IP.
  • Use the CDMA-1x IP address on the PDSN as controller or member IP when provisioning.
  • Provision the newly added Cisco PDSN with the HA to service MIP calls.

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:

http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/957_pp.htm

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
 
A summary of U.S. laws governing Cisco cryptographic products may be found at: http://www.cisco.com/wwl/export/crypto/tool/stqrg.html

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.


NoteRunning the reload command on the active SUP causes both the active and standby Supervisors to reload simultaneously, causing some downtime during the upgrade process. 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:

maintain.html#wp1047551

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 brief
P indicates configured to preempt.
|
Interface Grp Prio P State Active Standby Virtual IP
Gi0/0.101 300 110 Standby 20.20.101.10 local 20.20.101.101
 
7600a-Stdy# show cdma pdsn redundancy
CDMA PDSN Redundancy is enabled
 
CDMA PDSN Session Redundancy system status
PDSN state = STANDBY HOT
PDSN-peer state = ACTIVE
 
CDMA PDSN Session Redundancy Statistics
Last clearing of cumulative counters never
Total Current

Sessions 15 15
SIP Flows 15 15
MIP Flows 0 0
PMIP Flows 0 0
 
7600a-Stdy# show redundancy inter-device
Redundancy inter-device state: RF_INTERDEV_STATE_STDBY
Scheme: Standby
Groupname: pdsn-rp-sr1 Group State: Standby
Peer present: RF_INTERDEV_PEER_COMM
Security: Not configured
 
7600a-Stdy# show redundancy states
my state = 8 -STANDBY HOT
peer state = 13 -ACTIVE
Mode = Duplex
Unit ID = 0
 
Split Mode = Disabled
Manual Swact = Enabled
Communications = Up
 
client count = 9
client_notification_TMR = 30000 milliseconds
RF debug mask = 0x0
 
7600a-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.

Step 7 Configure the current standby Cisco PDSN using the procedures described from Step 1 to Step 5.


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)XR10

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.

Users are unable to setup session when subscriber count reaching almost near to the max configured pool range due to address allocation or address distribution limitation in single ip . With the present single-ip ip pool distribution logic, 2 out of 7 parts(total pool / 7) are held with Pcop, and remaining 5 are distributed such that one to each Tcop.

Due to this there are so many IPCs, and due to IPC failures, some time Tcop may not get the IP address though there is enough free chunk of pool range with the Pcop.

1. Configure extra IPs, if possible.

2. Less idle-timeout value also frees the aged users, and that way more IPs with the Tcops.

Whenever the port range is configured in the packet filter the PDSN RTP data is not flowing through the A10 auxiliary connections.

Configure the port number in the mobile node rather than the port ranges in the packet filter.
