Cisco Cisco IPS 4255 Sensor 릴리즈 노트

The URL points to where the update file is located, for example, to retrieve the update using FTP, enter 
the following:

sensor(config)# upgrade ftp://username@ip_address//directory/IPS-engine-E3-req-6.1-1.pkg

Enter the password when prompted.

Enter password: ********

Enter 

 to complete the upgrade.

Installing the E3 engine update does not require the sensor to reboot except for the AIM IPS. For 
the duration of the update and subsequent software initialization, IPS inspection is halted and 
data bypassed according to the bypass configuration of the sensor.

In some rare instances, the E3 engine upgrade causes the CLI to hang during the install, and 
attempts to log in to the sensor CLI fail.  Rebooting the sensor restores functionality.

The following upgrade notes and caveats apply to IPS 6.1(1)E3:

If you are using automatic upgrade with the AIM IPS, NME IPS, and other IPS appliances or 
modules, make sure you put both the minor version upgrade file, IPS-K9-6.1-1-E3.pkg, the AIM IPS 
upgrade file, IPS-AIM-K9-6.1-1-E3.pkg, and the NME IPS upgrade file, 
IPS-NME-K9-6.1-1-E3.pkg, on the automatic update server so that the AIM IPS and NME IPS can 
correctly detect which file needs to be automatically downloaded and installed. If you only put the 
minor version upgrade file, IPS-K9-6.1-1-E2.pkg, on the automatic update server, the AIM IPS and 
NME IPS will download and try to install it, which is the incorrect file for the AIM IPS and 
NME IPS.

To install the IPS-K9-6.1-1-E3.pkg, IPS-AIM-K9-6.1-1-E3.pkg, or IPS-NME-K9-6.1-1-E3.pkg 
minor upgrade file, you must be running IPS version 5.0(1) or later on your sensor. Use 
IPS-AIM-K9-6.1-1-E2.pkg to upgrade the AIM IPS only. Use IPS-NME-K9-6.1-1-E3.pkg to 
upgrade the NME IPS only. Use IPS-K9-6.1-1-E2.pkg for all other supported sensors.

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

After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest 
software features.
