Cisco Cisco IPS 4255 Sensor

UDP length parameter in Atomic engines 

A new parameter to match a specific UDP length was added. This engine parameter is added in 
the Atomic IP Advanced and Atomic IP engine for l4-protocol UDP. The purpose of this 
parameter is to check if UDP total length falls within a specific range.

For IPS standalone appliances with 1 G and 10 G fixed or add-on interfaces, the maximum jumbo frame 
size is 9216 bytes. 

A jumbo frame is an Ethernet packet that is larger than the standard maximum of 1518 bytes (including 
Layer 2 header and FCS).

Cannot launch the IDM.

When the IDM is running under JRE 1.7 and the IPS version is 7.1.5 or earlier.

Use JRE 1.6 or enable the SSL 2.0-compatible ClientHello format in the Java settings in the 

Control Panel.

For IPS 7.1(6) and later, the IDM functions with JRE 1.7.

Because MySDN has been decommissioned, the URL in older versions of the IDM and the IME is no 
longer functional. If you are using IPS 6.0 or later, we recommend that you upgrade your version of the 
IDM and the IME.
