Cisco Cisco IPS 4255 Sensor 릴리즈 노트

The following restrictions and limitations apply to Cisco IDM 7.2.2:

After you upgrade the IPS software on your sensor, you must restart the IDM so that the latest 
features for the new software version are present in the IDM. 

The IDM opens MySDN from the last browser window you opened, which is the default setting for 
Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet Options, 
and then click the Advanced tab. Scroll down and uncheck the Reuse windows for launching 
shortcuts check box.

For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no 
password cisco command, but you cannot remove it. To use the no password cisco command, there 
must be another administrator account on the sensor. Removing the cisco account through the 
service account is not supported. If you remove the cisco account through the service account, the 
sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system 
image.

The IDM does not support any non-English characters, such as the German umlaut or any other 
special language characters. If you enter such characters as a part of an object name through IDM, 
they are turned into something unrecognizable and you will not be able to delete or edit the resulting 
object through IDM or the CLI. This is true for any string that is used by the CLI as an identifier, 
for example, names of time periods, inspect maps, server and URL lists, and interfaces.
