Adding Remote Devices

Each instance of the Sensor Control must know which remote devices are under its control, since it might discover devices that are intended for another Sensor Control. Use this page to add remote devices to the Sensor Control, then connect and disconnect them as necessary.

There are three ways in which you can associate a remote device with the appropriate instance of the Sensor Control:

• Manual Definition: Remote device parameters are entered in the Sensor Control one at a time.

• Remote Device Definition List: Parameters for multiple remote devices are imported as a batch using a CSV (Comma-Separated Value) file.

• Via the Discovery Inventory: Remote devices that have been discovered by the Sensor Control(using the remote device discovery instances that were created in the Discovery ▶ Configuration page) can be added here individually or in groups of up to 25 devices.

The list of all remote devices that have previously been added to the Sensor Control appears here when you first open the page. For more information, see the section below.

Remote Devices ▶ Configuration page

Accedian Sensor Control devices, are described in the following table which lists the types and corresponding names.

Accedian Module Types and Device Names

For information on specific parameters, refer to the following section.

Remote Device Parameters (Remote Devices ▶ Configuration)

Remote Device Name: A name that uniquely identifies the remote device across the network. (Max 25 characters.)

MAC Address: The base MAC address of the remote device (for example 00:15:AD:1D:72:00). This address value is incremented by 1 to assign a MAC address to the second port of the device (for example 00:15:AD:1D:72:01).
Serial Number: The unique serial number assigned to the remote device.
Security Key: The device-specific Grain-128a security key that is associated with each device. The expected format is 00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF

The security key is used to establish a secured session between the Sensor Control and the remote device. These sessions are used to report the link state, as well as to ensure that the parameter and register settings on the remote device can be managed from the Sensor Control instance.

To use the Accedian Management Key (AMK) as the security key, leave this field blank. The AMK ensures a universal authentication mechanism on Accedian devices; its value can be used to connect to all newly-shipped devices that have never been managed.

Regardless of the type of security key being used to protect the remote device, the key value is periodically changed to prevent the management sessions with the Sensor Control from being spoofed.

Linked: Indicates whether or not the remote device is currently linked to this instance of the Sensor Control.

Vendor: Indicates whether the device is a Cisco-branded or Accedian-branded remote device.

Type: The type of remote device.

Linking Devices to the Sensor Control

The Linked column of the summary table indicates whether or not the remote device has been linked to this instance of the Sensor Control.

The Linked column will display one of four possible statuses:

• No: The remote device is not linked to the Sensor Control
• Yes: The remote device is linked to the Sensor Control
• Initializing: The remote device is being initialized prior to linking to the Sensor Control
• Updating: The remote device is linked to Sensor Control and the firmware update is in-progress
• Update failed: The remote device is linked to Sensor Control and the firmware update failed

A remote device is considered linked to a Sensor Control when the following are true:

• It has been added to the Sensor Control and configured properly, including authorization.
• It has been discovered by the Sensor Control and a management session between the remote device and the Sensor Control has been successfully established.

No direct intervention on your part is required to link a device to a Sensor Control. Once linked, the remote device’s physical ports are added to the list of ports available on the Sensor Control.

Unlinking Devices From the Sensor Control

You can unlink a remote device from its Controller simply by revoking the Sensor Control 's authorization over the device.

To unlink a remote device from the Sensor Control

1. Access the page Remote Devices ▶Configuration.
   A listing of all devices currently associated with this instance of the Sensor Control is displayed.

2. Click the name of the remote device that you want to unlink from the Sensor Control.
   The Remote Device Configuration page is displayed. Details related to the selected device are provided.

3. Revoke the Sensor Control's authorization over the remote device by clearing the Connect check box.
   The selected device is automatically unlinked from the Sensor Control.

Using the FlexMonitor

The FlexMonitor check box is used to enable the FlexMonitor feature. The FlexMonitor instance with the UNI port connected receives monitored traffic for the flowmeter and flow broker.

Enable this feature when the remote device is not in-line with network traffic. By using a mirror port and sending monitoring traffic on the UNI port, management is performed on an NNI port. The FlexMonitor feature disables the port and prevents it from forwarding traffic from the NNI to the UNI port, as well as from the NNI to the UNI port.

When the UNI port is not connected, the FlexMonitor feature is not in use.
