Cisco Cisco IPS 4255 Sensor

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 the 
IDM, they are turned into something unrecognizable and you will not be able to delete or edit the 
resulting object through the 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 the SensorApp is reconfigured, there is a short period when the SensorApp is unable to 
respond to any queries. Wait a few minutes after reconfiguration is complete before querying the 
SensorApp for additional information. 

The IDM and the 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.

This section describes how to recover the password for the sensor. It contains the following topics:

Password recovery implementations vary according to IPS platform requirements. Password recovery is 
implemented only for the cisco administrative account and is enabled by default. The IPS administrator 
can then recover user passwords for other accounts using the CLI. The cisco user password reverts to 
cisco and must be changed after the next login.
