Problems in vlan and my secondary network adapter in nanostation ac

Installing and Using OpenWrt Network and Wireless Configuration
1

In the Ubiquiti configuration I have my two network interfaces and manage them as I please, in openwrt it becomes a switch0 with vlan: one interface eth0, two vlan eth0.1 and eth0.2; where is the secondary interface or the supposed eth1, any guide for a configuration similar to that of Ubiquiti?

Many devices have just one link between the CPU and the internal switch. In this case, LAN and WAN traffic must be separated using VLANs.

If this is the case, just use eth0.1 and eth0.2 as your interfaces.

Thanks for answering
How can I install eth1 to the cpu?

Drivers that abstract the switch out of the picture so to the administrator it looks like there are separate "real" eth ports is called DSA. OpenWrt only uses DSA on a few models. The different configuration scheme here doesn't limit what the hardware actually can do. If you only need two simple untagged ports just refer to them as eth0.1 and eth0.2. If you need VLANs to appear on the Ethernet cable you will need to configure the switch separately.

You cannot, and you do not need it.

Please post here the output of uci export network

In your case:

UBNT	OpenWrt
eth0	eth0.1
eth1	eth0.2

Treat them like this, it is only the name that changed, nothing else.
