IDSM2 with IPS5.1 (on cat65K sup 720 IOS 12.2SXF) will support ? Inline ? mode.But does it support ? blocking? as well ? ??
? CCO document says ?Supervisor 720 with Cisco IOS supports VACL deny statements; however, IDSM-2 cannot block with Cisco IOS-style VACLs.
? Here VACL deny means ? not consider to monitor that particular VLAN or IP address ? right ? OR is it like totally blocking the user traffic? Or blocking the connection from the respective host/connection/IP.

Hi Rajan,
All sensors can block on supported network devices
regardless of whether the sensor is configured as
inline. In the case where an IDSM2 is installed on
a Catalyst switch running IOS, and the user wants
the sensor to block on the switch, the blocking
device should be specifed as a router. The sensor
will block with ACLs, not VACLs. Blocks can either
be unconditional (denying all packets from the
attacker) or connection oriented.
One point to keep in mind is that a sensor in inline
mode can also perform inline deny actions like "deny packet inline", "deny attacker inline", etc. These
deny actions are unrelated to the sensor blocking
response.
Regards,
Sean

Hi Sean,
Thanks for your valuable info.Now IDSM can block on cat6k after selecting the blocking device as Router(initially I had selected as cat6K.I need to test the same with inline pairs after sometime.
