3. Troubleshooting Functional Failures During Operation
164
If the track operating status is
Init, the track is stopped
because it is immediately after startup. Wait until the startup
waiting time elapses.
If the track operates, yet the track type is ICMP, go to No. 2.
2 Check whether IPv4 communication can be made
with track target
For the destination address, source address, and
next hop, use the same values as for the track
settings.
• Execute the
ping command.
If the ping destination address and responding address are
different, the address that responded is the subnet broadcast
address of the destination address.
IPv4 ICMP polling monitoring does not operate when the
destination is a broadcast address.
Check the configuration.
If the track has no next hop specified, and there is no
response or the response is unstable, check the network
communication between the Switch and the track target
device.
If the track has a next hop set, and there is no response or
the response is unstable, go to No. 3.
3 Check whether IPv4 communication can be made
with the router set as the next hop
• Execute the
ping command.
If communication with the device specified as the next hop
is unstable, check the IPv4 network communication
between the Switch and the next-hop device.
If communication with the device specified as the next hop
is stable, check the IPv4 network communication between
the next-hop device and the track target device.
