Setting vlan using bridge vlan

Hello, I want to set a vlan using bridge vlan add dev eth0 vid 10
in the /etc/config/network i added a new section

config vlan 'myvlan'
option device 'eth0'
option vlanid '99'
option pvid '1'
option untagged '1'

and in the /etc/init.d/network i added the bellow snippet is this right to do?

EXTRA_COMMANDS="setmyvlan delmyvlan"
EXTRA_HELP=<<EOF
		SET a vlan with configs from the config file network
		DEL a vlan with configs from the config file network
EOF

CONFIGURATION=network

setmyvlan(){
	config_load "${CONFIGURATION}"
	local device
	local vlanid
	local pvid
	local untagged
	

	config_get device myvlan device
	config_get vlanid myvlan vlanid
	config_get pvid myvlan pvid
	config_get untagged myvlan untagged
	
	echo "adding a vlan to the device:$device with an ID: $vlanid"
	bridge vlan add dev $device vid $vlanid
	bridge vlan
}

You don't need to edit /etc/init.d/network or script anything to add a vlan. It's enough to edit /etc/config/network, then run /etc/init.d/network reload. The section you added does not look correct though. Was it generated by a LLM? The equilvalent of the command bridge vlan add dev eth0 vid 10 would be

config device
    option type '8021q'
    option ifname 'eth0'
    option vid '10'
    option name 'eth0.10'

config interface
    option device 'eth0.10'
    option proto 'none'

The device section is not strictly needed. option device 'eth0.10' automatically creates a vlan subinterface with vid 10 on eth0.
If your device has an integrated switch, you may want to use switch-vlans instead, or bridge-vlans if the device uses DSA. See here for more info: https://openwrt.org/docs/guide-user/network/vlan/switch_configuration#creating_driver-level_vlans

Almost certainly this is entirely wrong -- in fact, I don't think anything in your post would work as expected.

Bridge VLANs are required for DSA. They can be used in certain circumstances on non-DSA devices, but typically it is better to use swconfig syntax (on swconfig devices) or dotted notation on devices with individually routed ports.

The example provided below is not actually the equivalent for a bridge VLAN as it uses dotted notation. The 802.1q stanza is not necessary and the interface may or may not be correct, depending on the hardware in use. Usually the interface will have a name, even when it is unmanaged.

The best way to move forward in this situation is to see the default config from the device:
