This Product Bulletin describes the content and delivery information concerning Cisco IOS™ software release 12.3(8)XW, the release vehicle for the Packet Data Serving Node Release 2.0, and migration vehicle for the Cisco IOS software release 12.3(7)XJ, the initial release vehicle for Mobile Wireless Home Agent 2.0. This release is focused on the Cisco 7206VXR, 7600, and Catalyst 6500 platforms. The 7600 and 6500 utilizes the Multi-Processor WAN Application Module (MWAM). The features delivered with this release will be incorporated into the 12.4(1st)T release, but 12.3(8)XW represents a release vehicle that provides these features sooner. For more information about the Cisco IOS software release process, please see Product Bulletin #537.
MIGRATION GUIDE
Figure 1 below displays Cisco IOS 12.3(8)XW release functionality relative to the 12.3 and 12.3T releases. This diagram also identifies the migration path.
This is also the migration path for the previous Early Deployment release 12.3(7)XJ.

Detailed Information
On-Demand Address Pools (ODAP)
Cisco On Demand Address Pool (ODAP) feature supports the capability of a large IP address pool per chassis. Each separate PDSN processor will request a subnet of IP addresses from the large IP address pool. Local pools per member would not need to be configured at all; one main pool would be configured on a Centralized Server. The benefits include more efficient use of IP addresses, centralized management benefits, and simplified operational procedures.
Prepaid Per IS-835C
The Prepaid feature provides PDSN to AAA server support of the prepaid VSAs, as defined in Is-835C. It provides real time metering of Simple IP, Proxy Mobile IP and VPDN based services. It also provides undifferentiated real time metering of Mobile IP services. "Undifferentiated" means that all the Mobile IP flows for a single user will be rated equally. Metering can be based on data volume or call duration. Note that the AAA server must support the defined VSAs, and be integrated with a Prepaid Billing Server (PBS).
Resource Revocation Per IS-835C
This allows the PDSN to clean up an HA binding (e.g. when call drops) as well as allows HA to clean up a PDSN session, e.g. on handoff. This is the implementation of the standardization of Cisco binding update feature available in HA R1.2 with an additional enhancement.
Packet of Disconnect (PoD) Per IS-835C
This provides a trigger mechanism to cancel sessions on the PDSN and/or HA. The trigger can come from AAA, billing mediation, etc. (whoever is controlling the access). It can be used alone, or in conjunction with Resource Revocation feature, to clean up the session/binding. This means that resources are not wasted.
Always on Per IS-835B
The always-on service maintains a subscriber's packet data session irrespective of ppp inactivity timer value for the user. At the same time, by making use of a finite ppp inactivity timer value, this feature provides a compromised approach to keep a session only as long as the user is reachable.

On-Demand Address Pools (ODAP)
Cisco On Demand Address Pool (ODAP) feature supports the capability of a large IP address pool per chassis. Each separate HA processor will request a subnet of IP addresses from the large IP address pool. Local pools per member would not need to be configured at all; one main pool would be configured on Centralized Server. The benefits include more efficient use of IP addresses, centralized management benefits, and simplified operational procedures.
Home Agent Server Load Balancing (HA-SLB)
The Server Load Balancing (SLB) function runs on the Supervisor and front ends a pool of HAs, providing load balancing across a group of HAs running on the MWAMs listed in its server farm. Only one virtual IP address must be known to the FA. Note that the proper option is also required on the Supervisor image to enable this feature. See Ordering section for 6500 and 7600 starting on Page 10 for details.
Resource Revocation Per IS-835C
This allows PDSN to clean up an HA binding (e.g. when call drops) as well as allows HA to clean up a PDSN session, e.g. on handoff. This is the implementation of the standardization of Cisco binding update feature available in HA R1.2 with an additional enhancement.
Packet of Disconnect (PoD) Per IS-835C
This provides a trigger mechanism to cancel sessions on the PDSN and/or HA. The trigger can come from AAA, billing mediation, etc. (whoever is controlling the access). It can be used alone, or in conjunction with Resource Revocation feature, to clean up the session/binding. This means that resources are not wasted.
HA Redundancy Enhancements
This is an enhancement to the existing HA Redundancy feature. It adds support for the feature when local pool IP addressing, or proxy DHCP addressing, is utilized.
Conditional Debugs
Enhancement made to existing conditional debug feature to add support for Mobile IP.
Hotlining
Uses standard IS-835C based CoA messages to change user session profiles at the start of the session or in mid session. Data packets from the subscriber in the upstream can be re-directed to a different server, which will capable of handling these packets. This provides support for "web steering" statically configured by realm and dynamically configured per user within the realm. Example is a prepaid user who runs out of quota can be redirected mid session.
VRF
HA can have virtual HAs which are using the Virtual Router Function (VRF) to support address overlapping. Thus, one HA can provide connection to different corporate users using a different transport.
For more detailed information about the platforms and features being delivered in 12.3(8)XW, please reference the following documents:
Note: Cisco Software Application Support (SAS) must be ordered for the PDSN; it is not covered under Smartnet. See Product Numbers section below for details. Cisco SAS includes 24-hour technical assistance from the Cisco Technical Assistance Center (TAC) via telephone and the Web, online tools, plus bug fixes, maintenance, and rebuilds of the same release (R2.0) of PDSN and HA.
Product Numbers
The spare product code is designated with `=' and should be ordered when moving to a different PDSN or HA image, or when the platform hardware is not being ordering conjunction with the software.
There are two PDSN images available with R2.0: Basic and Premium.
• Basic-Includes basic feature set. 10k session capacity on 7206VXR; 20k session capacity on MWAM
• Premium-Includes basic feature set plus Prepaid. 20k session capability on 7206VXR and MWAM
There are two HA images available with R2.0: Basic and Premium.
• Basic-Includes basic feature set
• Premium-Includes basic feature set plus Hotlining, VRF
There are two options when ordering software for the MWAM:
• Single Image
• Bundled Image
Each single image contains one PDSN image to run on one of the five MWAM processors; each bundled image contains five PDSN images that run on each of five MWAM processors.
When ordering more than one single image, the first one should be ordered as an option to the MWAM. Any subsequent single images, should be ordered as spares.
The following are additional ordering guidelines and sample configurations for a Home Agent. Note that the configurations are provided for guidance only and do not include hardware Smartnet contracts, or ancillary equipment such as cables, rack mount kits, or high speed fan trays. Please discuss your desired configuration with your Cisco representative prior to ordering.
HA and PDSN R2.0 on 7206VXR
The PDSN and HA images operate on a 7206VXR; it can be used on the NPE-400, providing backward compatibility to R1.2, and on the NPE-G1. All new orders must utilize the NPE-G1.
Following is the recommended hardware configuration for a 7206VXR to be ordered as a PDSN or HA R2.0.

HA and PDSN R2.0 on 7600
HA and PDSN operate on separate MWAMs. They can be licensed by MWAM (5 processors), or by processor (single image). Note that PDSN and HA images can not coexist on the same MWAM, though an HA MWAM and a PDSN MWAM can coexist in the same chassis.
The 12.2.17d-SXB1 software version must run on the supervisor. The HA and PDSN on MWAM are only supported with the SUP2/MSFC2.
Following is the recommended hardware configuration for a 7613 to be ordered as an HA and/or PDSN R2.0. Recommended supervisor software is also included.
