Interfaces
Ping test: Uses ICMP to determine connectivity. The default behavior is to ping the
l
interface gateway, which means that an initial traceroute is sent to the hostname or IP
address configured in the SureLink advanced settings, and then the first hop in that route
is used for the ping test.
DNS test: Performs a DNS query to the named DNS server.
l
HTTP test: Uses HTTP(s) GET requests to determine connectivity to the configured web
l
server.
Test DNS servers configured for this interface: Tests communication with DNS servers
l
that are either provided by DHCP, or statically configured for this interface.
Test the interface status: Tests the current status of the interface. The test fails if the
l
interface is down. Failing this test infers that all other tests fail.
Custom test: Tests the interface with custom commands.
l
TCP connection test: Tests that the interface can reach a destination port on the
l
configured host.
Test another interface's status: Tests the status of another interface.
