parameter in the ‘sys’ interface. The MAC addresses are specified as a list of 48-bit addresses
separated by commas. An example of setting this parameter is shown below.

15.2 Backhaul Health Monitoring
A gateway node can monitor its connectivity to a remote device to ensure that its backhaul
connection is functioning properly. If a gateway determines that it has lost connectivity over its
backhaul link, it will stop advertising its gateway capability to nodes in the mesh cluster. If the
backhaul connection is re-established, the gateway will revert to advertising its gateway
services. While the backhaul link is down the gateway will switch to repeater mode and will
forward traffic from other mesh nodes and its clients.
The backhaul health monitoring function has no effect on a node configured as a
repeater.
Backhaul health monitoring is enabled with the ‘monitor.health.enable’ parameter in the ‘sys’
interface as shown in the example below.
> use sys
sys> set monitor.health.enable=yes
The health monitoring scheme, if configured incorrectly, can incapacitate a mesh
cluster. If the device that is used to check the state of the backhaul link fails or if an
address that the gateway cannot reach is specified, the gateway will not function
properly and it will not be possible to communicate with it over the backhaul link.
The host that the gateway uses to test backhaul health is specified with the
‘monitor.health.host’ parameter in the ‘sys’ interface. The device specified with this parameter
must be capable of responding to ping, or ICMP echo, packets from the gateway for the health
monitoring to function properly. The example below shows how to set this parameter.
> use sys
sys> set monitor.health.host=10.0.1.1
