• The deployment procedure with the Local Manager is not supported by firmware version 17.3.x. Perform the Procedure with the Cisco Cyber Vision sensor management extension instead.

• Monitor sessions based on physical ports for IE3400 and IE3300 switches only capture ingress packets. If the monitor sessions do not capture all ports, the DPI results are incomplete, inaccurate, or missing.

• Cisco Catalyst 9300: deployments will be possible for sensors on firmware version 17.6.x as of Cisco Cyber Vision version 4.0.1.

• IOx redundancy is not supported: sensors will not persist after a failover. This applies to stacks of Cisco Catalyst 9300, stacks of Cisco Catalyst 9300X, and Cisco Catalyst 9400 with redundant processor boards.

• IOx redundancy is not supported: sensors will not persist after a failover. This applies to stacks of Cisco IE9300 with redundant processor boards.

• The sensor application supports RSPAN on Catalyst 9x00 in addition to ERSPAN in Cisco Cyber Vision version 4.1.3. In case of RSPAN usage, multicast packets and packets VLAN information are not transferred to the sensor application.

• Active discovery is not possible on a network configuration where the Center and the sensor are on different networks with L3nat-IOx as L3nat-IOx is not able to NAT more than one interface.
