Cisco Cisco IPS 4255 Sensor

The BIOS on Cisco IPS sensors is specific to IPS sensors and must only be upgraded under instructions 
from Cisco with BIOS files obtained from the Cisco website. Installing a non-Cisco or third-party BIOS 
on IPS sensors voids the warranty. 

All IPS platforms allow ten concurrent CLI sessions.

The AIM IPS and the NME IPS do not support the IPv6 features, because the router in which they are 
installed does not send them IPv6 data. IPv6 inspection may work on the IDSM2, but we do not officially 
support it. There is no support for IPv6 on the management (command and control) interface.
