Geofencing

Geofencing is a location-based feature that includes

defining a geographical boundary within which a device can be deployed,
configuring alerts to be sent to Cisco SD-WAN Manager or a mobile number when a device leaves the geographical boundary, and
restricting network access when a device leaves the specified boundary.

Geographical boundary

Devices use Global Positioning System (GPS) functionality provided by a Long-Term Evolution (LTE) Pluggable Interface Module (PIM) to determine the device location.

You can configure these for geofencing:

Base location (latitude and longitude) and a geofence range for device detection
Short message service (SMS) alert registration for sending SMS messages to a mobile number
GPS enablement on an LTE PIM in the controller cellular 0/x/0 section

Geofencing status alerts are sent to Cisco SD-WAN Manager upon detection of device boundary violations.

Overview

Configuration

In Cisco SD-WAN Manager, you can use operational commands for restricting network access if a device exceeds its geographical boundary. For information on the operational commands for restricting network access, refer to the Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide.
From Cisco vManage Release 20.7.1, you can configure geofencing using a Cisco System feature template.

Benefits of geofencing

Protects against inappropriate access to an organization's network if a device is beyond its geographical boundary
Notifies end users of any displaced devices
Supports a geofence radius for specifying the target location of the device
Supports SMS alerts for mobile phone alerts

Configure geofencing

Geofencing is a location-based feature that enables defining a geographical boundary within which a device can operate.

Use one of these methods to configure geofencing:

Feature template
CLI commands

Configure geofencing using templates

Geofencing is a location-based feature that enables defining a geographical boundary within which a device can operate.

From Cisco vManage Release 20.7.1, you can configure geofencing using a Cisco System feature template.

Before you begin

Follow these steps to configure geofencing using a feature template.

Step 1	From the Cisco SD-WAN Manager menu, choose Configuration > Templates.
Step 2	Click Feature Templates. In Cisco vManage Release 20.7.x and earlier releases, Feature Templates is titled Feature.
Step 3	Click Add Template.
Step 4	Choose a device.
Step 5	In the Select Template > Basic Information section, click Cisco System.
Step 6	In the Template Name field, enter a name for the template. The name can be up to 128 characters and can contain only alphanumeric characters.
Step 7	In the Template Description field, enter a description of the template. The description can be up to 2048 characters and can contain only alphanumeric characters.
Step 8	In the Basic Configuration section of the Cisco System template, choose a value from the drop-down list for Console Baud Rate (bps). Console Baud Rate (bps) is a mandatory field for configuring geofencing.
Step 9	Click GPS or navigate to the GPS section of the Cisco System template.
Step 10	In the Latitude field, leave the field set to Default for automatic detection of a device. Range: -90.0 - 90.0
Step 11	In the Longitude field, leave the field set to Default for automatic detection of a device. Range: -180.0 - 180.0. Note If you manually specify Latitude and Longitude coordinates, you disable automatic detection of a device. Automatic detection of a device can fail if a device does not have a last-known valid location.
Step 12	In the Geo Fencing Enable field, change the scope from Default to Global, and click Yes to enable geofencing. The Geo Fencing Enable field is not enabled by default.
Step 13	(Optional) In the Geo Fencing Range in meters field, specify a geofencing range unit in meters. The geofencing range specifies the radius from the base target location in meters. The default geofencing range is 100 meters. You can configure a geofencing range of 100 to 10,000 meters.
Step 14	(Optional) In the Enable SMS drop-down list, change the scope to Global, and click Yes to enable SMS alerts. An SMS alert is delivered when a device is determined to be outside the configured geofencing radius of its target location. Note The presence of a SIM card is mandatory in the Long-Term Evolution PIM for receiving SMS alerts.
Step 15	(Optional) In the Mobile Number 1 field, add a mobile number for receiving SMS alerts. Note Mobile numbers must start with a + sign, include a country code, an area code, with no spaces between the country code and the area code, and the remaining digits. Sample mobile number: +12344567236. You can configure additional mobile phone numbers by clicking the + icon. You can configure up to a maximum of four mobile numbers.
Step 16	Click Save.

Configure geofencing using CLI commands

Geofencing is a location-based feature that enables defining a geographical boundary within which a device can operate.

For information on the operational commands for restricting network access, refer to the Cisco Catalyst SD-WAN Monitor and Maintain Configuration Guide.

Before you begin

Follow these steps to configure geofencing using CLI commands:

Step 1

Configure latitude, longitude, a geofence range, and SMS alerts.

Configure a base location latitude and longitude.

Example:

Device(config)# system
Device(config-system)# gps-location latitude 37.317342 longitude -122.218170

Enable automatic detection of a device where the device determines its own location.
Example:
```
Router(config)# system
Router(config-system)# no gps-location latitude
Router(config-system)# no gps-location longitude
Router(config-system)# gps-location auto-detect-geofencing-location
```
Do not configure latitude and longitude coordinates when using the auto-detect-geofencing-location parameter.

You can choose to either configure a base location using latitude and longitude coordinates, or you can enable automatic detection of a device.
Enable, configure, and specify a geofence range.

For geofencing range, the unit is meters. Geofencing range is an optional configuration parameter, and if not configured, it takes the default value of 100 meters.
Example:
```
Device(config-system)# gps-location geo-fencing-enable
Device(config-system)# gps-location geo-fencing-config
Device(conf-geo-fencing-config)# geo-fencing-range 1000
```

Add mobile numbers for receiving SMS alerts.

Example:

Device(config-geo-fencing-config)# sms                                                                       
Device(config-sms)# sms-enable
Device(config-sms)# mobile-number +12344567234
Device(config-mobile-number-+12344567234)# exit
Device(config-mobile-number-+12344567234)# mobile-number +12344567235
Device(config-mobile-number-+12344567235)# exit
Device(config-mobile-number-+12344567235)# mobile-number +12344567236
Device(config-mobile-number-+12344567236)# exit
Device(config-mobile-number-+12344567236)# mobile-number +12344567237
Device(config-mobile-number-+12344567237)# exit
Device(config-sms)# commit

Step 2

Enable GPS on an LTE PIM.

These are example CLI configurations for enabling GPS on an LTE PIM in the 0/x/0 section of the configuration.

Enable GPS on an LTE PIM in the controller cellular section.

Example:

Device(config)# controller Cellular 0/2/0
Device(config-Cellular-0/2/0)# lte gps enable

Enable ms-based mode with a SIM card present in an LTE PIM.

We recommend that you use ms-based with a SIM card present.

Mobile station-based assistance refers to the case where the Global Navigation Satellite System (GNSS-enabled) mobile device computes its own position locally.
Example:
```
Device(config-Cellular-0/2/0)# lte gps mode ms-based
```
Enable National Marine Electronics Association (NMEA) streaming.
Example:
```
Device(config-Cellular-0/2/0)# lte gps nmea
```
