Network

The Network menu includes setup and status information for DNS, NTP, PTP, Livewire Clock, SNMP, and each of the available LAN interfaces.

DNS

Select Network (A) from the System > Network menu to begin, then choose DNS (B) to open the DNS page. Displayed information (C) includes:

• DNS State - Displays the IP address of the actual DNS server(s).

• mDNS Node Name - Shows the name used for mDNS (Bonjour, Avahi)

• DNS - Field for manually entering the IP address of a DNS server.

NTP

Select NTP (A) from the Network menu to open the NTP page. Displayed information (B) includes:

• NTP State - Displays the current NTP server.

• Enable NTP - Enables and disables NTP.

• Use Fallback NTP - When enabled, uses the internet NTP servers at debian.pool.ntp.org if the unit cannot connect to the specified NTP servers.

• NTP Server - Fields for entering up to four local NTP server addresses.

PTP

Select PTP (A) from the Network menu to open the PTP page. Displayed information (B) includes:

• PTP Clock Domain - The field for entering the proper PTP clock domain.

• PTP DSCP Class - Options include 0, 8 CS1, 10 AF11, 16 CS2, 18 AF21, 24 CS3, 26 AF31, 32 CS4, 34 AF41, 40 CS5, 46 EF (AES67), 48 CS6 (Ravenna), and 56 CS7. 48 CS6 (Ravenna) is the default setting.

Livewire Clock

Select Livewire (A) from the Network menu to open the PTP page. Displayed information (B) includes:

• Mode - Choose "Follower" or "Disabled," as Livewire cannot act as a Leader.

• Network Interface - Selects the network interface used for Livewire.

• Locked to Leader - Indicates when Livewire is locked to the Leader clock.

• Leader ID - The IP address of the Leader clock.

• Offset - Displays the difference (delay) between the local clock and the Leader in microseconds.

• Jitter - Displays the variations in delay between the local clock and the Leader in microseconds.

SNMP

Select SNMP (A) from the Network menu to open the SNMP page. Displayed information (B) includes:

• Enable - Enables and disables SNMP.

• Community - Identifies the SNMP Community string.

• Host Name, System Location, and System Contact - Populated fields from the System Setup menu.

• Trap Sink IP Address - The IP Address of the SNMP trap receiver.

• Trap Sink Port - The port of the SNMP trap receiver.

LAN Interfaces

A total of four LAN interfaces are available. The LAN 1 CTRL and LAN 2 interfaces operate in a similar fashion to one another, so the information below applies to both.

LAN 3/4 differs from LAN 1 and LAN 2 in that they are internally connected by a switch to the network chip which is in turn connected to the SoM via a PCIe link. Therefore, they share the same IP Address, Gateway, MAC Address, and PTP settings.

Interface Menu

Choose the individual Interface (A) for each LAN under the Network menu. In the example below, we've chosen the LAN 1 CTRL interface. Displayed information (B) includes:

• Link Up - Indicates the presence of an active, working link (True or False).

• Speed - The current link speed and type (100Mb/s, Full Duplex).

• RX Bytes - Indicates the number of bytes received since the link was made active.

• TX Bytes - Indicates the number of bytes transmitted since the link was made active.

• RX Throughput Bps - The actual measured receive throughput.

• TX Throughput Bps - The actual measured transmit throughput.

• MAC Address - The MAC address of the interface.

IP Menu

Select IP (A) for the selected LAN under the Network menu.

The Current IP Addresses section (C) displays the current dynamic and static IP addresses.

When Use Dynamic Addresses (B) is enabled, the unit will automatically retrieve an IP address from the network's DHCP server. When disabled, the specified static IP address is used instead.

Static IP Addresses are listed in the Static Addresses window section (D). Clicking the Edit button (E) will open a pop-up window where the address type (IPv4 or IPv6) and subnet mask may be defined. Clicking the Delete button (F) removes the selected static IP address.

To add a new static IP address, click on the Add IP Address button (G), which will open a pop-up window where the address type, IP address, and subnet mask information can be entered.

Clicking the Restore Factory Defaults button (H) will set the LAN to DHCP and remove all static IP addresses.

Gateway Menu

Select Gateway (A) for the selected LAN under the Network menu.

The Current Gateways section (B) lists the current gateways.

The Static Gateways section (C) lists the IP addresses of any manually-added gateways along with any specific actions. To add a new gateway, click on the Add Gateway button (D) which will open a pop-up window to enter the new address.

PTP Menu

Select PTP (A) for the selected LAN under the Network menu.

The Status section (B) contains the following information:

• Hardware PTP Capable - Indicates when the Ethernet hardware is capable of extracting a PTP sync.

• PTP Status - Options include None, Initializing, Faulty, Disabled, Listening, Pre-Leader, Leader, Passive, Uncalibrated, and Follower.

• Locked to Leader - Indicates when PTP is synced to a Leader clock on the network.

• Leader ID - Displays the MAC address of the PTP Leader.

• Distance to Leader - Shows the number of hops between the Leader and flexAI unit.

• Offset from Leader (us)

• Mean Path Delay (us)

The Configuration section (C) contains the PTP Mode control. Options include Disabled and Follower, as flexAI cannot be used as a PTP Leader device.
