Network Diagnostics
The gateway provides diagnostic tools directly through the user interface for network troubleshooting:
ping – Tests the reachability of a host on the network.
DNS lookup – Queries the DNS.
traceroute – Displays the route packets across the network.
TCP Connect – Tests whether a specific TCP port is open.
Wake – Remotely awakens computers using the WoL (Wake on LAN) command.
To use network diagnostics:
1 In the CONFIGURATION tab, select System > Network in the navigation pane.
The Network page is displayed.
2 Click Diagnostics.
The Network Diagnostics window is displayed.
3 In the Diagnostic Tool field, select the tool you want to use.
The window changes to reflect the diagnostic test requested.
Ping – Tests the reachability of a host on the network.
DNS Lookup – Queries the DNS.
Traceroute – Displays the route packets across the network.
TCP Connect – Tests whether a specific TCP port is open.
Wake – Remotely awakens computers using the WoL (Wake on LAN) command based on the MAC address of the computer or broadcast IP.
iPerf – Measures the maximum achievable upload and download bandwidths using either TCP or UDP.
Note: The iPerf diagnostic option dopes not work on C200 gateways.
where:
Address – The address of the computer to measure.
Port – The port to measure.
Threads – The number of threads to test the connection.
TCP or UDP – The protocol to measure.
Measure Upload or Measure Download – The direction to measure.
The following command is run: iperf -c {Address} -fM -m -i5 -t25 -p {Port}
if the number of threads is changed from the default, 1, the command is run with the -P flag with the thread number. For example, iperf -c {Address} -fM -m -i5 -t25 -p {Port} -P 10
if UDP is specified, the command is run with the -u flag. For example: iperf -c {Address} -fM -m -i5 -t25 -p {Port} -u
4 Enter the information required for the test, such as the IP address you want to ping.
5 Click Go.
The test results appear in the Network Diagnostics window.
6 Click Close when you have completed the diagnostic tests.
