Outlines the preparation of switches and routers for Cyber Vision Sensor deployment, including storage configuration, clock synchronization, IOx service enablement, verification steps, and prerequisite requirements.
To deploy a Cyber Vision Sensor application in the routers and switches in your network, you must first prepare the devices.
-
Configure storage
This step does not apply to Catalyst 9x00 switches and the IR routers. These devices support IOx applications on internal storage.
The Cisco Cyber Vision Sensor application requires dedicated and compatible storage to install files, store configuration data, and manage logs. Format or partition storage, such as an SD card or SSD, to create a compatible file system for the Linux-based environment. The sensor application requires ext4. This preparation lets the switch's operating system (IOx) recognize, allocate, and write data to storage. Without this step, you cannot install or run the sensor application.
-
Synchronize clocks
The sensor application obtains its time from the host device. We recommend using an NTP server so that the various devices in your network are synchronized.Using an NTP across devices enables accurate monitoring, effective security analysis, and reliable communication with the central Cyber Vision Center. It also ensures the integrity of all data collected by the Cyber Vision Sensor.
Synchronize all device and IOx application clocks to UTC. -
Enable the IOx service
IOx is an application hosting framework. It allows applications to run directly on Cisco network devices. Enabling IOx activates a specialized environment on the device and provides the necessary runtime, resources, and isolation. This environment allows the sensor application to operate independently from the device core operating system (IOS XE). Without IOx, there is no platform or dedicated environment for the Cyber Vision Sensor application.
Before you begin
To carry out this taskflow, ensure that:
-
SSH access to the device is available.
-
The device is running a supported IOS XE software version.
-
If you wish to use SD card on a device, the card must be 4 GB or greater.
For instructions on setting up the prerequisites, refer to the configuration guides for the specific device.

If an IOx application does not have the necessary read and write permissions, the application may not initiate or function correctly.
