December 2002
Cisco IOS Release 12.2(8)ZB is a special release that is based on Cisco IOS Release12.2, with the addition of enhancements to the Cisco Home Agent feature. The Cisco IOS Release 12.2(8)ZB is a release optimized for the Cisco Home Agent Release 1.2 feature on the Cisco 7206VXR router platform, and the Cisco Multi-Processor WAN Application Module on the Cisco 6500 Catalyst Switch platform. 7206VXR images will be available starting with first maintenance release, 12.2(8)ZB1. The current image for the 7206VXR routers is 12.2(8)BY2.
Contents
These release notes include important information and caveats for the Cisco PDSN software feature provided in Cisco IOS 12.2(8)ZB for the Cisco 7206 series router platform.

Obtaining Technical Assistance
Introduction
The Home Agent (HA) maintains mobile user registrations and tunnels packets destined for the mobile to the PDSN/FA. It supports reverse tunneling, and can securely tunnel packets to the PDSN using IPSec. Broadcast packets are not tunneled. Additionally, the HA performs dynamic home address assignment for the mobile. Home address assignment can be from address pools configured locally, through either DHCP server access, or from the AAA server.
System Requirements
This section describes the system requirements for Cisco IOS Release 12.2(8)ZB:
•
•
•
Memory Requirements
Table 1 shows the memory requirements for the PDSN Software Feature Set that supports the Cisco 7206 router. The table also lists the memory requirements for the IP Standard Feature Set (for the Home Agent [HA]).
Hardware Supported
Cisco IOS Release 12.2(8)ZB is optimized for Cisco Home Agent Release 1.2 on the Cisco 7206VXR router platform, and the Cisco Multi-Processor WAN Application Module on the Cisco 6500 Catalyst Switch platform.
The recommended hardware configuration for a Release 1.2 Cisco Home Agent is a 7206VXR with NPE400-512MB and PA-FE-TX1 port adapters. This is the only configuration tested in the Cisco lab. Cisco does not support or test any other variations of this configuration. If you require a different configuration you should consult with your Cisco representative before you order.
The recommended hardware configuration for Home Agent Release 1.2 is based on a Catalyst 6500 chassis with a SUP2, and 512 MB of DRAM. The recommended MWAM configuration calls for 512 Meg RAM per processor, totalling 1Gigabyte per processor complex.
An IPSec Services Module (VPNSM) is required for hardware support of IPSec.
For a complete list of interfaces supported on 6500 platform, please refer to the on-line product information at Cisco.com home page. For hardware details on 6500 platform, please refer to the Catalyst 6500 product specifications at http://www.cisco.com/en/US/products/hw/switches/ps708/index.html).
Software Compatibility
Cisco IOS Release 12.2(8)ZB is a special release that is developed on Cisco IOS Release 12.2.
Cisco IOS Release 12.2(8)ZB supports the same features that are in Cisco IOS Release 12.2, with the addition of the Cisco Home Agent Release 1.2 feature.
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 EXEC command:
Router# show versionCisco Internetwork Operating System SoftwareIOS (tm) 6500 Software (C6500-H1IS-M), Version 12.2(8)BY, RELEASE SOFTWAREUpgrading to a New Software Release
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
MIBs
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 2.
Cisco IOS Feature Sets
The 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.
Cisco IOS Release 12.2(8)ZB supports the same feature sets as Cisco Release 12.2, with the exceptions that Cisco Release 12.2(8)ZB includes the Cisco Home Agent Release 1.2 feature. The Home Agent Release 1.2 feature is optimized for the Cisco 7206 router, and the Cisco 6500 Catalyst Switch.
Caution
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
Caveats for Cisco IOS Releases 12.2 can be found on CCO at http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cavs/122mcavs.htm
The "Open Caveats" section lists open caveats that apply to the current release and might also apply to previous releases.
The "Resolved Caveats" section lists caveats resolved in a particular release, which may have been open in previous releases.
Note
Open Caveats
This section describes possible unexpected behavior in Cisco IOS Release 12.2(8)ZB.
•
On the HA, data packets sent to MN immediately after the session establishment will be dropped. This happens only for the first MN on the tunnel, and with the tunnel scalability feature enabled.
There is no workaround.
•
On the HA, the tunnel input bytes in show ip mobile tunnel output indicates the wrong value (some extra bytes) when CEF is enabled.
There is no workaround.
Resolved Caveats
This section lists bugs that are resolved or closed in Cisco IOS Release 12.2(8)ZB.
•
When multiple, redundant, RADIUS servers are configured for authentication on the HA, and the primary RADIUS server fails, MoIP sessions fail to come up. RRQs are rejected with "Identification Mismatch".
The HA compares the RRQ's timestamp with it's own timestamp only after receiving an Access-Accept. In the abnormal case where the Access-Accept is delayed, the RRQ is rejected.
As a workaround, the timeout for the radius server may be set to a value less than the replay protection period.
•
While opening and closing MOIP sessions using 6500 MWAM PDSN, the HA reloads when the show ip mobile tunnel command is issued.
There is no workaround.
•
In the case of HA Redundancy, whenever a packet to the MN needs to be fragmented, but the DF bit is set, ICMP unreachable packet will not be sent to the sender of the packet.
A workaround is to disable the Tunnel scalability feature.
