Cover the following interface
This option selects the physical interface to assign to the logical interface being created. If ‘Create a bridge
over multiple interfaces’ is selected, you can select multiple options.
Option Function
Ethernet Adapter ‘erspan0’ Currently not available in this software.
Et hernet Adapter ‘eth1’ This selects the ETH1 port.
Ethernet Adapter ‘eth2’ This selects the ETH2 port.
Bridge This selects the virtual bridge/switch. Multiple virtual
switch instance (VSI) can be created/used.
Ethernet Adapter ‘ loop0-7 ’ This selects a loopback adaptor.
This is a virtual adaptor allowing assignment of IP
addresses that will always be active.
This type of adaptor cannot be used as part of a bridge.
Ethernet Adapter ‘sfp1’ This selects the SFP port.
Ethernet Adapter ‘teq10’ Currently not available in this software.
Ethernet Adapter ‘w l an0’ This selects the Wi-Fi modem.
Ethernet Adapter ‘ wwan0 ’ This selects the cellular modem.
This type of adaptor cannot be used as part of a bridge.
Custom Allows creation of custom VLAN tag interfaces. See below
for details.
Custom: VLAN interface
This allows creation of virtual 802.1q VLAN tag interfaces. For example, entering ‘eth1.100’ creates an
interface that uses 802.1q packets with VLAN id 100 on ETH1.
Custom: VLAN bridge
To pass for example VLAN id 100 between ETH1 and ETH2, enter ‘eth1.100’ and ‘eth2.100’.
To create a VLAN bridge with ETH1 having id 100, ETH2 having id 200, and SFP being a trunk port:
First create a new logical interface, select ‘ Create a bridge over multiple interfaces ’, and th en select
‘eth1.100’ and ‘sfp1.100’.
Next create a second logical interface, s elect ‘ Create a bridge over multiple interfaces ’, and then select
‘eth2.200’ and ‘sfp1.200’.
Note: It is not necessary to assign an IP address to every bridge interface. If the Aprisa LTE only needs to do
L2 switching on a given VLAN, and not participate in any conversations, then it is normal to use Static
protocol, and leave the Address, Netmask etc blank/unassigned.
Custom: Stacked VLAN
It is possible to stack multiple 802.1q VLAN tags. For example to have an inner tag of 100, and outer tag of
200:
First the outer VLAN create a new logical interface, then enter custom interface of ‘eth1.200’. Select
Static protocol, and leave address, netmask etc blank/unassigned.
Next create a second logical interface, then enter custom interface of ‘eth1.200.100’.
