Interface numbering

The interfaces have their own numbering in the Secure SD-WAN Manager called the interface ID. The interface IDs are mapped to the corresponding network interfaces on the Engine when you configure the Engine software.

Table 1. Interface numbering for Engines
Interface type Interface numbering in the Secure SD-WAN Manager
Layer 3 physical

(Firewall/VPN role)

Each physical interface has a unique interface ID number.
Layer 2 physical

(Firewall/VPN role)

Physical

(IPS and Layer 2 Firewall roles)

VLAN Each VLAN interface has a VLAN number. The defined VLAN interfaces are displayed, for example, as “5.202” for network interface 5 with VLAN 202.
ADSL Each ADSL interface has a unique interface ID number. ADSL interfaces are only supported on legacy Engine appliances.
Wireless The wireless interface has a unique interface ID number. An SSID (service set identifier) interface represents an 802.11 wireless LAN. You can add several SSID interfaces to the wireless interface.
Modem Modem Interfaces are identified with modem numbers. The modem number is mapped to the modem’s IMEI (international mobile equipment identity) number. Each modem is assigned a unique ID when you connect the modem to the engine. You can change the mapping between the modem’s IMEI number and the modem ID through the engine command line, if necessary.
Tunnel Tunnel interfaces are numbered with tunnel interface ID numbers. The mapping of Tunnel Interfaces to physical network interfaces on the engine is done automatically by the engine operating system based on the routing configuration.
Integrated switch

Integrated switches are identified with switch IDs. Integrated switches have predefined switch IDs. For example, the switch ID is 0 on Engine 110 appliances.

You can add port group interfaces to switches. Port group interfaces are identified by port group IDs. The defined switches and port group interfaces are displayed, for example, as 0.1 for switch ID 0 with port group 1.
