® announces the availability of Cisco
® Home Agent Service Manager 4.0 for configuring and troubleshooting Cisco Home Agent. As part of the Mobile Wireless Center for Cisco Mobile Exchange suite of applications, Cisco Home Agent Service Manager complements the CiscoWorks LAN Management Solution (LMS) to provide end-to-end management of Cisco Mobile Exchange (Figure 1). The Mobile Wireless Center addresses the element-management requirements of mobile operators and provides fault, configuration, and troubleshooting capability as mobile operators transition their networks from second-generation (2G) circuit-based traffic to 2.5G and third-generation (3G) IP-based services.
Mobile Wireless Center for Cisco Mobile Exchange
Cisco Home Agent forms part of the Cisco Mobile Exchange framework, which offers mobile operators a standards-based framework that links the radio access network (RAN) to IP networks and their value-added, content-based IP services. Cisco Mobile Exchange enables the intelligent framework that identifies users, knows where they are, and delivers services to them anywhere, over any access medium, to any client device. In this context, Cisco Home Agent identifies a host device by a single IP address even if the device moves its physical point of attachment from one network to another. The result: subscribers with mobile devices can roam to another network without restarting applications or terminating and re-establishing a connection.
Cisco Mobile Wireless Home Agent is deployed at the mobile operator's data center. It resides on the Cisco Catalyst
® Series Multiprocessor WAN Application Module, which is used in the Cisco Catalyst 6500 Series and the Cisco 7600 Series platforms. All traffic sent to the subscriber terminal is routed through the home agent, regardless of the network where the traffic originates. Likewise, traffic from the subscriber terminal is also routed through the home agent, regardless of its ultimate destination. As a result, the subscriber retains a constant connection and remains addressable even while roaming across different access networks. That is, Cisco Mobile Wireless Home Agent serves as an anchor point for subscriber PCs or PDAs, no matter how many times the subscriber changes link types and crosses network boundaries.
Cisco Mobile Exchange uses the proven Cisco 7600 Series Router platform to deliver all of the connectivity needs required, including support for General Packet Radio Service (GPRS), Universal Mobile Telecommunications Service (UMTS), Code Division Multiple Access 2000 (CDMA2000), wireless LAN (WLAN), packet data serving node (PDSN), and tunneling protocols such as generic routing encapsulation (GRE), IP Security (IPSec), and Layer 2 Tunneling Protocol (L2TP).
A typical IP-based CDMA2000 mobile wireless network built around Cisco Mobile Exchange is represented in Figure 2, where the Cisco Home Agent solution provides proxy Address Resolution Protocol (ARP) services to wireless subscribers.
In this context, Cisco Home Agent Service Manager has functions for provisioning and troubleshooting Mobile IP services to efficiently activate services and improve network reliability. Integrated with CiscoWorks LMS, Cisco Home Agent Service Manager provides a GUI similar to other CiscoWorks applications and interacts with the CiscoWorks Common Services Job Browser, making it a powerful tool for bidirectional device interaction and status. Furthermore, the Cisco Home Agent Service Manager console allows easy navigation through configuration and troubleshooting tasks in a familiar environment.

Home Agent Service Activation
Cisco Home Agent Service Manager provides a Web-based GUI to create, modify, and delete services within the Cisco Home Agent-Cisco Mobile Exchange complex to support seamless roaming to customers, by offering an always-on IP connection that persists independent of location, movement, or wireless infrastructure. Cisco Home Agent also provides the ability to forward packets at rates appropriate for each connection based on the quality of service (QoS). Cisco Home Agent Service Manager activates, deactivates, and modifies the following services within Cisco Home Agent:
• Local IP Pools
• Virtual Networks
• Home Address Assignment (with or without NAI)
• Mobile IP Mobility Security Association
• Home Agent VRF Sub-Network
• Hot Lining
Figure 3 shows one of the Cisco Home Agent provisioning consoles.

Home Agent Configuration Discrepancy Analysis
Cisco Home Agent Service Manager also provides the capability of analyzing home agent configuration discrepancies within the defined grouping to proactively flag questionable configurations and prevent service-impacting misconfigurations. The Sync Report dashboard provides an intuitive report card that shows devices out of sync status as shown in Figure 4. The dashboard also allows the operator to see the actual commands that are not matching.
Cisco Home Agent Service Manager Console for Configuration Discrepancy Analysis
Cisco Home Agent Service Manager features a troubleshooting dashboard that provides predefined key information on:
• Home agent show commands outputs
• Home agent debug results
• Home agent syslog messages
