# Network Diagnostics

The CTERA Edge Filer 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. **iPerf** – Measures the maximum achievable upload and download bandwidths using either TCP or UDP.

**To use network diagnostics:**

1. In the **Configuration** view, select **System > Network** in the navigation pane.  

The **Network Interfaces** 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**, **DNS Lookup**, and **Traceroute** all require an address.  

**Ping** – Tests the reachability of a host on the network.  

**DNS Lookup** – Queries the DNS.  

**Traceroute** – Displays the route packets across the network. For example:

**TCP Connect** – Tests whether a specific TCP port is open.

Or:

**Wake** – Remotely awakens computers using the WoL (Wake on LAN) command based on the MAC address of the computer. For more details, see [Remotely Awakening Computers](/v1/docs/remotely-awakening-computers-5-1-1-1-1).  

**iPerf** – Measures the maximum achievable upload and download bandwidths using either TCP or UDP.  

![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-VO05OBZ6.png?sv=2026-02-06&spr=https&st=2026-11-11T04%3A43%3A45Z&se=2026-11-11T05%3A43%3A45Z&sr=c&sp=r&sig=JPWjc%2B%2FSSGF%2FFtaqP%2Fh%2BTXyGSu3eIkKKQOpFC8ZXpn4%3D)  

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 are displayed in the window, under the tool details.
6. Click **Close** when you have completed the diagnostic tests.
