Configure Network Parameters

Configure the Roving Edge Device network settings through your controlling host that's connected to the serial port.

Note

For a list of serial console commands, see Operating the Serial Console

From the controlling host terminal window, select the Configure the Network menu option. The following options are displayed:
- Set Node IP Settings (Current Node Only): Set the node IP address, subnet mask, and default gateway.
- Display Settings: Show the current network settings.
- Set Public IP Pool Range for Compute Instances: Set the external IP address pool for compute instances.
  
  IP addresses are allocated from this pool when an instance is created with public IP address assigned to it.
  
  Important – This operation removes the current external IP address pool, and replaces it with the ranges from the new input.
  
  The best practice is to use a contiguous range of IPs. An ideal range is a CIDR range such as 10.10.0.0 - 10.10.0.15, which corresponds to 10.10.0.0/28, which is what is stored internally.
  
  If you're updating your public IP pool range, none of the IPs in the existing range can be allocated to a compute instance during the operation. The best practice is to ensure all public IPs are dissociated with all compute instances before updating your public IP pool range.
- Display Public IP Pool Status: Show the current public IP pool range.
- Control Network Ports: Enable or disable network ports.
- Configure DNS: Configure the DNS servers for the current node control plane. Reboot the device for the DNS configurations to take effect, if the device is already unlocked.
- Configure Subnet Gateway: Configure the gateway for a given subnet. The destination can be the default IGW or a private IP Address. You can perform the following tasks:
  - Show Configuration: Show the current subnet gateway configuration. The output shows whether the destination is IGW or a private IP address for each subnet.
  - Update Configuration: Update the current subnet gateway configuration. For example:
```
---------------------------------------------------------------------------------------------
Idx  Subnet CIDR      DNS Label     Gateway
---------------------------------------------------------------------------------------------
1    10.0.1.0/24      Subnet-1      10.0.2.2
2    10.0.2.0/24      Subnet-2      IGW
3    10.0.3.0/24      Subnet-3      IGW
                                    
Enter Subnet Index: 1
Enter the gateway (IGW or private IP address) for this subnet:
```
- Configure NTP: Perform the following NTP configuration tasks:
  - Display NTP Configuration: Configure external NTP servers. For example:
```
Local Time and RTC
Local time: Fri 2022-05-13 04:26:41 UTC
Universal time: Fri 2022-05-13 04:26:41 UTC
RTC time: Fri 2022-05-13 04:26:43
Time zone: UTC (UTC, +0000)
NTP enabled: n/a
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
```
  - Update NTP configuration: Identify the primary and secondary servers that set up the NTP configuration for the device.
- Reset Network: Reset the network by erasing all the network configurations such as Node IP, Public pool, DNS, NTP, and Gateway.
- Help: Display online help for the Network Configuration menu options.
- Go Back: Return to the main serial console menu.
Use the menu options to configure the device network parameters according to your network environment. At minimum, configure these parameters:
- Network settings
- DNS
- NTP
