Cisco Cisco IPS 4255 Sensor

inside the adaptive security appliance. The configuration on the main adaptive security appliance 
can be used to designate which packets/connections should be monitored by the AIP SSM as either 
promiscuous or inline.

When deploying an IPS sensor monitoring two sides of a network device that does TCP sequence 
number randomization, we recommend using a virtual senor for each side of the device. 

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

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 CLI as an identifier, for example, names of time periods, 
inspect maps, server and URL lists, and interfaces.

You can only install eight IDSM2s per switch chassis.

When SensorApp is reconfigured, there is a short period when SensorApp cannot respond to any 
queries. Wait a few minutes after reconfiguration is complete before querying SensorApp for 
additional information. 

IDM and IME launch 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 most IPS platforms, you can now recover the password on the sensor rather than using the service 
account or reimaging the sensor. This section describes how to recover the password for the various IPS 
platforms. It contains the following topics:
