Interface Monitoring
As a complementary feature to Load Balancing, you can actively monitor each WAN connection to assure
that full network functionality exists.
Interface Monitoring must be enabled; it is off by default. It is set separately for each configured WAN
interface.
Three failures must occur before the system sets the port status to Unavailable and re-assigns subscribers.
Monitoring may be configured for both the Monitoring Interval (default is 60 seconds) and for three different
methods as required by the network:
The default method (Automatic) will generate a random DNS query to each configured DNS
server. Receiving an ?Error? back from the server(s) verifies full network connectivity.
Host Probing (Ping) — A Host or IPaddress can be pinged to verify connectivity via ICMP
response.
Host Probing (HTTP) will generate an HTTP GET to the configured Web address. The HTTP
response will verify network connectivity.
To view configured WAN interfaces, select
Configuration > Interface Monitoring in the Web
Management Interface. The Interface Monitoring Settings screen appears:
