Field Notice: FN - 62123 - Management Center for IPS Sensors (IPS MC) 2.1 Has a Serious Defect When Updating or Upgrading 5.x Sensors


June 21, 2005


Products Affected

  • IPS MC - 2.1

Problem Description

After performing an upgrade or update that was downloaded from Cisco.com or a Local Server using the Automatic Signature Donwload feature of the Management Center for IPS Sensors 2.1, the 5.x IPS Sensors will become unmanageable. The Sensor will continue to function properly and can be seen in the IPS MC, but the IPS MC will not be able to deploy configurations, import/re-import or perform any other functions to sensors running the same signature version.

Background

The IPS MC 2.1 Software has a defect in the Automatic Signature Download feature that corrupts the IPS MC database during the download and apply procedures. The IPS MC is capable of successfully performing the update or upgrade to the Sensor, but the process causes the IPS MC's database to become corrupt and not match the information that it has deployed to the Sensor. All Sensors that have been updated with the same Signature that has been corrupted in the IPS MC database will be unmanageable.

Problem Symptoms

If the IPS MC 2.1 Upgrade has been performed without the patch, and the 5.x Sensors are either updated or upgraded by the unpatched 2.1 IPS MC using the Automatic Signature Download feature, then the Sensors will become unmanageable.

Workaround/Solution

Immediately following the IPS MC 2.1 upgrade, apply the CSCsb19306 patch prior to performing any Sensor upgrades or updates and the manageability problem will be avoided.

If the Sensors have already been upgraded or updated with an unpatched version of IPS MC 2.1 using the Automatic Signature Download feature, then apply the CSCsb19306 patch and then re-import all of the Sensors in order to ensure that all signature versions are corrected.

The CSCsb19306 patch can be found on the Software Download page.
