Ethernet

Ethernet interfaces operate in Layer-3 routing mode by default. Interfaces are automatically created when a device is onboarded using a standard template. Additional interfaces can be added manually if needed.


GUI Configuration

Navigate to Device Settings → Network → Interfaces.

Interface List

The Interfaces list shows all configured interfaces with their current state:

Column Description
Name Interface identifier (e.g., eth0, eth1, vlan10)
Type Interface type — Ethernet (Physical), VLAN, Loopback, VXLAN Tunnel, etc.
Enable Toggle to administratively enable or disable the interface
Operating Status Live link state and traffic throughput (Tx/Rx Kbps or Mbps)
IP / Network Assigned IP address(es) and prefix
DHCP Server Summary of DHCP server pool range configured on this interface
Members Member interfaces (for bridge or bond types)
Description Optional label assigned to the interface

To add a new interface, click + Add Interface and select the interface type from the dropdown.

Add Interface

Available interface types include:

Type Description
Ethernet (Physical) Layer-3 routed physical port
VLAN (Sub-interface) 802.1Q tagged sub-interface on a physical port
Bond (LACP/802.3ad) Link aggregation group for bandwidth or redundancy
Bridge (Software Switch) Layer-2 software bridge combining multiple ports
GRE TAP (Layer 2) GRE tunnel operating in Layer-2 TAP mode
Loopback Virtual loopback interface

Assign a name to the new interface (or click on an existing interface name) to open the edit form.

Edit Ethernet Interface


Settings

Basic Settings

Field Description
Ethernet Interface Name Physical interface identifier (e.g., eth0, eth1). This maps directly to the OS-level interface name.
Admin Status Enable or disable the interface administratively
IPv4 Address Set to Static IPv4 Address to manually assign an IP, or DHCP to obtain one from an upstream server
IP Address / Prefix One or more IPv4 addresses in CIDR notation (e.g., 192.168.8.1/22). Click + Add IPv4 Address/Prefix to assign additional IPs.
IPv6 Address IPv6 address assignment (optional)
Description Free-text label for this interface

Note

Multiple IPv4 and IPv6 addresses can be assigned to a single interface. The first (primary) IP is used as the source address for routing decisions and DHCP server pool anchoring.

Other Settings

Click each option to expand and configure it:

Option Description
DynDNS Enable Dynamic DNS updates for this interface's IP address
Enable Tracking Enable interface tracking for VRRP failover or link-state monitoring
Link Speed/Duplex Override auto-negotiation — set speed to 10, 100, or 1000 Mbps and duplex to auto, full, or half (default: 1000 / auto)
MTU Maximum Transmission Unit in bytes (default: 1500). Reduce for tunneled interfaces to avoid fragmentation.
Proxy ARP Enable Proxy ARP so the device responds to ARP requests on behalf of hosts on other subnets
VRRP (High Availability) Configure VRRP for gateway redundancy on this interface
Route Metric Set the administrative distance/metric for routes via this interface
Netflow Export Enable NetFlow traffic export on this interface for flow-based monitoring
VRF Assign the interface to a VRF instance for network segmentation

CLI Configuration

Basic interface setup

interface eth0
  description "WAN uplink"
  speed 1000
  duplex auto
  mtu 1500
  ip address 61.13.198.166/30
  ip default-gateway 203.128.19.103
  enable

Reduced MTU (e.g., for tunneled or PPPoE WAN)

interface eth0
  mtu 1300
  ip address 61.13.198.166/30
  enable

Multiple IP addresses on one interface

interface eth1
  ip address 192.168.8.1/24
  ip address 10.0.0.1/30
  enable

Verification
