The Interface-x nodes under IPS Interfaces represent an interface (a single physical port, peer ports, or an interface group) on a particular Sensor. The number of interface nodes displayed depends upon the type of Sensor. Interface nodes are displayed individually by default because the default monitoring mode is SPAN mode.
Full-duplex Tap and Inline modes require two physical ports, and each mode uses these two ports to form a single logical interface. Therefore, all configuration and policy decisions are made at a logical interface level.
After a new Sensor is installed, a policy is inherited from the admin domain and enforced on all Sensor interfaces. Subinterfaces are user created within this resource, and can be edited here or from the Sub-interface-x resource node.
Tip
Interfaces can be allocated to child domains for specialized management.
The navigation path to the interface nodes is as follows:
Click the Devices tab.
Select the domain from the Domain drop-down list.
On the left pane, click the Devices tab.
Select the device from the Device drop-down list.
For a standalone Sensor, select IPS Interfaces → <interface name>.
For Sensors in a stack, select IPS Interfaces → <Stackname-node id> → <interface name>.
The primary tasks that you can perform are customizing policies, assigning policies, and configuring inspection options.
