Ubiquiti NanoBridge M5 – management VLAN

Using firmware version v5.3.3 there is no way to set management VLAN using a browser, but it can be easily set using SSH in a couple of steps as described below.

This blog post is now obsolete.

Edit rc.poststart script:

# vi /etc/persistent/rc.poststart

For example to set IP address 10.1.2.3 on vlan 123 and remove general IP address set in browser you can use such commands:

vconfig add br0 123
ifconfig br0.123 10.1.2.3 netmask 255.255.255.0 up
ifconfig br0 0.0.0.0

Make rc.poststart file executable and check changes:

XM.v5.3.3# chmod +x /etc/persistent/rc.poststart
XM.v5.3.3# /etc/persistent/rc.poststart

Store changes to flash if everything works as expected:

XM.v5.3.3# cfgmtd -w -p /etc/
Found Backup1 on[1] ...
Found  Active on[2] ...
Storing Active[1] ... [%100]
Active->Backup[2] ... [%100]

Reboot device:

XM.v5.3.3# reboot

ifconfig output:

XM.v5.3.3# ifconfig

Update

Since AirOS 5.5 everything can be done using browser.
