Cisco IOS Software IP Source Tracker Feature
Discontinuation

PBxxxx

Last updated: January 2007

This product bulletin serves as formal notification of the discontinuation of support for the IP

Source Tracker feature on all Cisco

platforms running Cisco IOS

Software T-train and mainline

Cisco IOS Software images. The capability to configure IP Source Tracker will be removed from

the upcoming Cisco IOS Software Release 12.4T (after the 12.4(13)T release) and from future T-

train and mainline releases.

Support for the IP Source Tracker feature will continue to be provided in the Cisco IOS Software

12.0S and 12.2S family releases.

Alternative Solutions

The IP Source Tracker feature allows you to gather information about the traffic flowing to a host

that is suspected to be under attack. This feature also allows you to trace an attack back to its

entry point into the network. If the traceback capability is a requirement for your network, you can

use the Cisco NetFlow feature, which provides a similar function for the platforms running the T-

train and mainline software images.
