Cisco Cisco IPS 4255 Sensor Notas de publicación

Do not remove power to the IDS 4215 during the update process, otherwise the upgrade can get 
corrupted. If this occurs, the IDS 4215 will be unusable and require an RMA.

This section provides information on upgrading to IPS 6.0(6)E3, and contains the following topics:

The following upgrade notes and caveats apply to upgrading to 6.0(6)E3:

The sensor must report its version as 5.1(5) or later for you to apply the 6.0(6)E3 service pack.

When you upgrade AIM-IPS, you must disable heartbeat reset on the router before installing an 
upgrade. You can reenable heartbeat reset after you complete the upgrade. If you do not disable 
heartbeat reset, the upgrade can fail and leave AIM-IPS in an unknown state, which may require a 
system reimage to recover. 

If you try to upgrade a 5.1(5) sensor to 6.0(6)E3, you may receive an error that Analysis Engine is 
not running:

sensor# upgrade scp://user@10.1.1.1/upgrades/IPS-K9-6.0-6-E3.pkg

Password: ********

Warning: Executing this command will apply a major version upgrade to the application 

partition. The system may be rebooted to complete the upgrade.

Continue with upgrade?: yes

Error: Analysis Engine is not running. Please reset box and attempt upgrade again.

If you receive this error, you must get Analysis Engine running before trying to upgrade again. This 
error is often caused by a defect in the currently running version. Try rebooting the sensor, and after 
reboot, run the setup command and remove the interfaces from the virtual sensor vs0. When it is not 
monitoring traffic, Analysis Engine usually stays up and running. You can upgrade to 6.0(6)E3 at 
this time. After the upgrade to IPS 6.0(6)E3, add the interfaces back to the virtual sensor vs0 using 
the setup command.

Or you can use the recovery CD (if your sensor has a CD-ROM) or the system image file to reimage 
directly to IPS 6.0(6)E3. You can reimage a 5.x sensor to 6.0(6)E3 because the reimage process does 
not check to see if Analysis Engine is running.
