Advanced Network Configuration

Modify Network Settings

If the Trustgrid service is unreachable the normal Network Configuration will be unavailable and it may be necessary to manually edit the network settings on the device to change the IP and DNS configuration. This can be done via the Advanced Network Configuration > Modify Network Settings option.

The file you are editing is a netplan configuration file. Only the WAN/outside interface should be configured via Netplan as all other interfaces are managed by Trustgrid. The file format is YAML so it is important that all sections are indented correctly. Each level is two spaces.

1. From the Advanced Network Configuration select the Modify Network Settings option

   

2. The file will be opened in a basic text editor. Use the arrow keys to navigate to the correct section and edit as needed. Once complete use TAB to move to OK (or Cancel to exit without saving).

   

3. You will be prompted to apply the changes. Select Yes to apply the changes.

   

4. You will then be asked if you want to save the changes permanently. Select Yes to save the changes.

   

5. The system will apply the changes and wait about 20 seconds for the network to stabilize.

   

6. After editing the file the change must be applied and then the Trustgrid service restarted.

Deleting the runtime file

A temporary file is created when the network settings are changed but not permanently saved. If this file exists you will see an option to delete it from the Advanced Network Configuration menu. Selecting this option will delete the file and the changes will be lost.

Change Interface Speed/Duplex

By default all interfaces are set to auto-negotiate speed and duplex settings. However, if the other interface is also set for auto negotiate it is common to end up with mismatched settings. (e.g. the port is configured for 100 full and the interface negotiates to 100 half) This can lead to performance problems and interface errors until the correct settings are hard set on the interface.

1. From the Advanced Network Configuration select the Change Interface Speed/Duplex option
2. Select the desired interface from the list.

   

3. Select the desired speed from the list.

   

4. Select the desired duplex from the list.

   

5. Select save to apply the changes.

Change Interface MTU

By default all interfaces set themselves to the typical MTU size for their environments (1500 for physical, VMware and Hyper-V, 9000 for AWS and Azure). However, if any device between the Trustgrid node and the resources it connects to (both control and data plane) is configured to use a smaller MTU size then this can cause problems.

To change the MTU size of the interface:

1. From the Advanced Network Configuration select the Change Interface MTU option
2. Select the desired interface from the list.

   

3. Enter the desired MTU size and select OK to apply the changes.
