Config¶

The file /etc/config/qmp is the central configuration file (based on UCI).

Network interfaces¶

config 'qmp' 'interfaces'
#       option 'configure_switch' 'eth0'                    # (uncomment line if available, e.g. WGT634U)
        option 'lan_devices'      'eth0 wlan1 dummy0'       # LAN (dhcp server)
        option 'wan_devices'      'eth1'                    # WAN (dhcp client)
        option 'mesh_devices'     'wlan0 wlan2 eth0 eth1'   # Mesh devices, will be extended by VLAN tag!
        option 'no_vlan_devices'   ''                       # Network devices where we do not want to use VLAN tag (not recommended!)

Node information¶

config 'qmp' 'node'
        option 'primary_device' 'eth0'
        option 'community_id' 'qMp'
