View and configure network interfaces on the Simplifyd Box device from the shell

Default Interface Configuration

Every Box router ships with the following default interface layout:

Interface	Mode	Default IP	Description
`wan0`	DHCP	—	Ethernet WAN uplink
`wan1`	DHCP	—	Ethernet WAN uplink
`wan2`	DHCP	—	Ethernet WAN uplink
`wwan0`	DHCP	—	4G/5G cellular modem (model-dependent)
`wwan1`	DHCP	—	4G/5G cellular modem (model-dependent)
`lan0`	Static	`192.168.200.1/24`	Ethernet LAN
`tun0`	—	assigned by gateway	Secure cloud tunnel

wwan0 and wwan1 are only present on models with internal 4G/5G modems (BXE2150C, BXW2150C).

Interface Naming Convention

Prefix	Type
`wan`	Ethernet WAN uplink
`wwan`	4G/5G wireless WAN
`lan`	Ethernet LAN
`wlan`	WiFi LAN (WiFi models)
`tun`	Virtual tunnel (cloud connection)

Viewing Interfaces

Show All Interfaces

show interfaces

Displays a table of all interfaces with their IP addresses, link state, and uplink connectivity status.

Example:

Uplink Connectivity values:

Yes — the interface has confirmed internet connectivity
No — the interface is up but cannot reach the internet
N/A — not applicable (LAN or tunnel interfaces)

Show a Single Interface

show interface <name>

Displays detailed configuration for a specific interface.

Example:

wan-edge-1615561 # show interface wan0
+------------------+----------------+
| Enabled          | true           |
| DHCP Enabled     | true           |
| IP Address       | 192.168.178.25 |
| Gateway Address  | 192.168.178.1  |

wan-edge-1615561 #

Configuring Interfaces

Assign a Static IP Address

intf <interface> set ip <address>/<mask> gw <gateway>

Example — assign 192.168.1.100/24 with gateway 192.168.1.1 to wan0:

intf wan0 set ip 192.168.1.100/24 gw 192.168.1.1

For LAN interfaces, the gateway is optional:

intf lan0 set ip 10.0.0.1/24

Enable DHCP

intf <interface> enable dhcp

Example:

intf wan0 enable dhcp

Enable an Interface

intf <interface> up

Example:

intf wan1 up

Disable an Interface

intf <interface> down

Example:

intf wan1 down

Set MTU

intf <interface> set mtu <value>

Example — set MTU to 1500 bytes on wan0:

intf wan0 set mtu 1500

The default MTU for tunnel traffic is optimized automatically. Only change the MTU on WAN interfaces if your ISP or upstream equipment requires a specific value.

VLAN Sub-interfaces

You can create 802.1Q VLAN sub-interfaces on any Ethernet interface to segment traffic.

Add a VLAN Sub-interface

intf <interface> add subintf-vlan <vlan-id>

Example — create VLAN 10 on lan0:

intf lan0 add subintf-vlan 10

This creates a sub-interface named lan0.10.

Remove a VLAN Sub-interface

intf <interface> del subintf-vlan <vlan-id>

Example:

intf lan0 del subintf-vlan 10

Adding and Removing IP Addresses

You can assign additional IP addresses to an interface without replacing the existing one.

Add an IP Address

add ip <address>/<mask> intf <interface>

Example:

add ip 10.0.0.10/24 intf lan0

Remove an IP Address

rm ip <address>/<mask> intf <interface>

Example:

rm ip 10.0.0.10/24 intf lan0
