Operating and Maintaining the Cisco Mobile Wireless Home Agent

This section describes configuration details, statistics, and MIBs supported by the Home Agent. A definitive description of each Mobile IP command can be found at the following URL: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fipras_r/1rfmobip.htm

The Home Agent can be managed using either the Cisco IOS CLI or using Cisco Works for Mobile Wireless.

Cisco's Mobile Wireless Home Agent has the following configurable parameters:

Managing user profiles (local users)

Configuring IP pools locally

Configuring security associations with communicating nodes

Configuring ingress/egress filtering

Configuring mobile binding updates

Configuring routing information

Statistics

The Mobile Wireless Home Agent maintains statistics on a global basis for the following parameters:

Advertisements, received and sent

Registrations, requests and replies

Registrations, accepted and denied

Bindings

Binding Updates

Gratuitous and Proxy ARPs

Route Optimization Binding Updates

The Mobile Wireless Home Agent maintains statistics on a per FA-HA tunnel basis for the following parameters:

Source and Destination IP address of the tunnel

Tunnel Type, IPinIP or GRE

Reverse Tunneling allowed

Number of Users using that tunnel

Traffic sent on the tunnel, packets and bytes

Traffic received on the tunnel, packets and bytes

The Mobile Wireless Home Agent maintains statistics per host, identified by NAI or home IP address, for the following parameters:

Lifetime

Session duration

Traffic transmitted to the host, packets and bytes

Traffic received from the host on the reverse tunnel, packets and bytes


Note The statistics can be cleared from the CLI. The MIB counters are not cleared.


SNMP, MIBs and Network Management

The HA implements SNMPv2 as specified in the suite of protocols: RFC 1901 to RFC 1908. The Home Agent supports the MIB defined in "The Definitions of Managed Objects for IP Mobility Support UsingSMIv2," RFC 2006, October 1995. An additional Cisco MIB, CISCO- MOBILE-IP-MIB provides enhanced management capabilities. The RADIUS MIB, as defined in RADIUS Authentication Client MIB, RFC 2618, June 1999. A full list of MIBs that are supported on the Ciscco 7200 Internet Router, Cisco 7600 Switch and Cisco 6500 Catalyst series platforms can be found at the following URL: http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml

Session counters maintained in the MIB cannot be reset using SNMP or the Cisco IOS CLI. Home Agent CPU and Memory Utilization counters are accessible using the CISCO-PROCESS-MIB.

Release 3.0 adds a Home Agent Version MIB Object.

Conditional Debugging

The HA supports conditional debugging based on NAI, as well as conditional debugging based on the MN's home address. Only AAA and Mobile IP components will support conditional debugging.

From the CLI, it is possible to trace activity of all or a particular user identified by NAI. Monitoring the activity of a particular user, called conditional debugging, will display the user activity related to Mobile IP messages and the RADIUS messages.

This release provides an option to display the condition (username/IMSI), along with each debug statement. This helps to match a debug statement to its condition. To enable this feature, use the following command:

ip mobile debug include username

The following MobileIP debugs are supported for conditional debugging:

debug ip mobile

debug ip mobile host

The following AAA debugs are supported for conditional debugging:

debug aaa authentication

debug aaa authorization

debug aaa accounting

debug aaa ipc

debug aaa attr

debug aaa id

debug aaa subsys

The following RADIUS debugs are supported for conditional debugging:

debug radius

debug radius accounting

debug radius authentication

debug radius retransmit

debug radius failover

debug radius brief

Monitoring and Maintaining the HA
