Network Devices

The Network Devices page in the Kentik portal allows you to view information about existing devices registered with Kentik and add or edit devices. The structure of the page is covered in the following topics:

• About Devices
• Supported Device Types
• Devices Page
• Device List
• Device Details
• Label Controls
• Device List Filters
• Device Settings Dialog
• Manage Devices

Notes:
- Device settings made in the Device Settings Dialog are covered in Device Settings.
- Devices may be set up during your organization's initial onboarding with Kentik (see Onboarding).
- For assistance with any aspect of adding or managing a device, contact Kentik (see Customer Care).

Devices are one of the primary types of Data Sources in Kentik, classified as either routers (including switches and firewalls) or hosts (utilizing Kentik's software host agent). They can send flow data (e.g., NetFlow, sFlow, IPFIX), be polled for SNMP data, and have BGP data read by Kentik. This data is correlated with other information like GeoIP and DNS in the Kentik Data Engine (KDE).

• Register the Device: Register a new device in the Kentik portal (see Manage Devices).
• Configure the Device:
  - For routers or networking hardware, see Router Configuration.
  - For hosts using Kentik’s software host agent, see Host Configuration.

Kentik supports devices in two main categories:

• Routers: Includes switches and firewalls.
• Hosts: Includes cloud resources.

These categories differ in how they store and report traffic and use different Device Settings. The table below lists the device types available in the portal, categorized accordingly. The types are listed in the order in which they appear in the Type drop-down on the General tab of the Device settings dialog (see Device General Settings).

Notes:
- All router types are fundamentally "NetFlow-enabled routers”. Choosing a specific device type (e.g., "Cisco IOS XR") allows for the collection of Device-specific Dimensions.
- Selecting "MPLS router" enables data collection for MPLS Dimensions but not for device-specific dimensions.

Note: In the Device API the above device types are referenced using the subtype values listed above.

The Devices page of the Kentik portal may be reached by choosing Settings from the main menu, then clicking Networking Devices (under Data Sources). All registered devices for your organization are listed on the page, which includes the following main UI elements:

• Share (on SubNav): Opens the Share dialog to enable you to share the current view (see Sharing via the Share Dialog).
• Actions (on SubNav): A drop-down menu from which you can choose to export or subscribe to the current view:
  - Export: Exports the page’s content as a visual report (PDF) or data table (CSV). A notification appears when the export is ready to download.
  - Subscribe: Opens the Subscribe dialog enabling you to subscribe to regular reports from the page, either by choosing an existing subscription (combination of email address and schedule) or specifying a new one. The form in the Subscribe dialog is the same as on the Subscription tab of the Share dialog, which is covered in Subscription Tab UI.
  - Unsubscribe: Opens the Unsubscribe dialog. Click the Subscription drop-down, select the subscription from which you’d like to unsubscribe, and click Unsubscribe.
  Note: Unsubscribe will only appear if you have an existing subscription for this page.
• Selection indicator: Indicates how many devices are currently selected in the Device list (see the Select column in Device List Columns). Label controls apply to the selected devices.
• Label controls: A set of buttons that allow you to manage labels for devices in the list (see Label Controls).

• Plan: The devices are grouped by their Kentik billing plan (see About Plans).
• Flow Type: The devices are grouped by the Flow Protocols used to send flow data to Kentik.
• Vendor: The devices are grouped by their manufacturer.

The Device list is covered in the following topics:

• About the Device List
• Device List Columns
• Device List Actions

The Device list is a table that shows information about your organization’s devices as well as available actions. By default, the list is ordered alphabetically by name (ascending). To change the sort order of the list, click on a heading to choose a sorting column, and on the resulting blue up or down arrow to choose the sorting direction (ascending or descending).

Each row of the Device list shows the device's values for each of the Device List Columns, as well as Device List Actions. You can also show an extensive set of additional details about the device by clicking on the device's row, which slides out the Device Details drawer from the right of the page. If the drawer is already open and you click on the row for a different device, the details will be replaced with details for the new device. To close the drawer, click anywhere outside of the Device list.

The columns displayed in the Device list depend on the settings selected in the Customize Columns popup (see Customize Device List). The following columns are available:

• Select All (checkbox in header row): A checkbox for toggling the selection state of all devices in the Device list:
  - If no checkboxes in the list are checked, or only some are checked, then clicking this checkbox will select all checkboxes.

• RTBH: Enabled if the device is assigned to an RTBH mitigation platform (see Configure Platform Devices).

Kentik's labeling feature enables you to create a label (essentially a property whose value is text) and apply it to one or more entities represented within the Kentik portal, creating a group that can be referenced collectively rather than individually (e.g. when filtering). The Devices page includes a set of label-related controls that are located above the Search field. The controls apply only to devices that are currently selected in the Device list:

• Add/Edit Labels: A link to the Labels page, where you can create, edit, or remove labels that are available to apply to the selected devices.
• Clear Labels: Clears the labels that are applied to all currently selected devices.
• Apply Labels: A field that shows, applies, and removes individual device labels (see Apply Labels Field).

The Apply Labels field is active only when one or more devices are selected in the Device list, at which point the field is populated with all labels that are already applied to any selected device. Clicking in the field will drop down a filterable list of labels; clicking on any listed label will add that label to the field and to all selected devices. Clicking the X at the right of a label in the field will remove that label from all selected devices.

Device list filters are available in the Filters pane, which is covered in the following topics:

• Device Filters Pane
• Filter Categories
• Filter Application Rules

The Filters pane to the left of the Device list includes a set of filters that you can use to narrow the list of devices that appear in the table (using Filter Application Rules). This pane includes the following types of controls:

• Reset to default (present only when one or more filters are specified): A button that removes all currently set filters.
• Collapse: A button that collapses the Filters pane. To expand the pane, click the Show/Hide Filters button (see Devices Page).
• Selection field: Each field displays lozenges for criteria selected from that field’s menu and filters the Device list to devices matching those criteria. To select criteria, click in the field and choose an item from the filterable drop-down list. To remove criteria, click the X at the right of its lozenge.
• Checkboxes: Checkboxes allow you choose one or more filter criteria for that category (see Filter Categories). Once checked, the criteria will appear as a lozenge in the Search field. To remove, click the X at the right of its lozenge or uncheck the box in the Filters pane.

Filter criteria for the Device list fall into the following categories:

• Site (selection field): Include only the devices at the selected sites.
• Flow Status (checkboxes): Include only devices whose status is:
  - Direct flow: Device’s flow is coming directly from a router or other network hardware.
  - Kentik Agent: Device’s flow is coming via Kentik's kproxy software agent (see Kentik Proxy Agent).
  - No flow: No flow is detected for the device.
• SNMP status (checkboxes): Include devices based on their current SNMP polling status (Detected or Not Detected).
• Streaming Telemetry Status: Include devices based on their current Streaming Telemetry status (Detected or Not Detected).
• BGP status (checkboxes): Include devices based on their current BGP peering status (Established, Not Established, or Not Configured).
• Plan (selection field): Include only devices with the selected billing plan (see Licenses).
• Label (selection field): Include only devices with the selected labels applied. After clicking the selection field, the drop-down list stays open to select multiple labels. Click off of the list to close it.
• Vendor (checkboxes): Filter devices based on the vendor specified as the device's manufacturer (derived via SNMP polling).
• Type (checkboxes): Filter devices of a given type (see Supported Device Types).
• Flow Type (checkboxes): Filter devices based on the format of the flow data: NetFlow v5, v9, IPFIX, or sFlow (see Flow Protocols).
• Credential (checkboxes): Filter devices based on the credentials used in the device’s settings (see Credentials Vault).

Kentik applies the following rules to filter categories and criteria:

• Criteria are ORed (match any) within categories and ANDed (match all) between categories.
• When criteria are selected in more than one category, a device is displayed only if it matches at least one of the selected criteria in all of the categories with criteria selected.
• When no criteria are selected for a category, the device may match any of the category’s listed criteria.

Adding or editing a device via the Kentik portal involves specifying information with the settings on the tabs of the Device dialog that opens when you click either the Add Device button or the Edit icon in the device's row of the Device list. These settings are covered in detail in Device Settings.

Devices are created and edited via the Devices page of the Kentik portal (choose Settings from the main menu, then Networking Devices under Data Sources). The add/edit process is covered in the following sections:

• Add a Device
• Edit a Device
• Remove a Device
• Enable BGP
