Network configuration in buildroot-ng
|
|
|
|
|
|
The network configuration in buildroot-ng is stored in /etc/config/network
|
|
and is divided into interface configurations.
|
|
Each interface configuration either refers directly to an ethernet/wifi
|
|
interface (eth0, wl0, ..) or to a bridge containing multiple interfaces.
|
|
It looks like this:
|
|
|
|
config interface "lan"
|
|
option ifname "eth0"
|
|
option proto "static"
|
|
option ipaddr "192.168.1.1"
|
|
option netmask "255.255.255.0"
|
|
option gateway "192.168.1.254"
|
|
option dns "192.168.1.254"
|
|
|
|
"ifname" specifies the Linux interface name.
|
|
If you want to use bridging on one or more interfaces, set "ifname" to a list
|
|
of interfaces and add:
|
|
option type "bridge"
|
|
|
|
It is possible to use VLAN tagging on an interface simply by adding the VLAN IDs
|
|
to it, e.g. "eth0.1". These can be nested as well.
|
|
|
|
This sets up a simple static configuration for eth0. "proto" specifies the
|
|
'protocol' used for the interface. The default image usually provides 'none'
|
|
'static', 'dhcp' and 'pppoe'. Others can be added by installing additional
|
|
packages.
|
|
|
|
When using the 'static' method like in the example, the options "ipaddr" and
|
|
"netmask" are mandatory, while "gateway" and "dns" are optional.
|
|
DHCP currently only accepts "ipaddr" (IP address to request from the server)
|
|
and "hostname" (client hostname identify as) - both are optional.
|
|
|
|
PPP based protocols (pppoe, pptp, ...) accept these options:
|
|
username:
|
|
The PPP username (usually with PAP authentication)
|
|
password:
|
|
The PPP password
|
|
keepalive:
|
|
Ping the PPP server (using LCP). The value of this option
|
|
specifies the maximum number of failed pings before reconnecting.
|
|
The ping interval defaults to 5, but can be changed by appending
|
|
",<interval>" to the keepalive value
|
|
demand:
|
|
Use Dial on Demand (value specifies the maximum idle time)
|
|
|
|
(pptp)
|
|
server: The remote pptp server IP
|
|
|
|
For all protocol types, you can also specify the MTU by using the "mtu" option.
|
|
|
|
|
|
|
|
|
|
Setting up the switch (currently broadcom only)
|
|
|
|
|
|
The switch configuration is set by adding a 'switch' config section.
|
|
Example:
|
|
|
|
config switch eth0
|
|
option vlan0 "1 2 3 4 5*"
|
|
option vlan1 "0 5"
|
|
|
|
On Broadcom hardware the section name needs to be eth0, as the switch driver
|
|
does not detect the switch on any other physical device.
|
|
Every vlan option needs to have the name vlan<n> where <n> is the VLAN number
|
|
as used in the switch driver.
|
|
As value it takes a list of ports with these optional suffixes:
|
|
|
|
'*': Set the default VLAN (PVID) of the Port to the current VLAN
|
|
'u': Force the port to be untagged
|
|
't': Force the port to be tagged
|
|
|
|
The CPU port defaults to tagged, all other ports to untagged.
|
|
On Broadcom hardware the CPU port is always 5. The other ports may vary with
|
|
different hardware.
