Got the same problem but with edgerouter-x and gl.inet mt-1300 - both mt7621

After upgrading to OpenWrt 21.02-SNAPSHOT r16248-089efd61e9 / LuCI openwrt-21.02 branch git-21.196.35996-de8bc46

Before upgrading (r16247)

ezplanet:

Bridge configuration:

config device
option name 'br-lan'
option type 'bridge'
option mtu '1492'
option ipv6 '0'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'

ezplanet:

I resolved it by changing the switch configuration as follows:

config device
option type 'bridge'
option name 'switch0'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'
option mtu '1492'

config bridge-vlan
option device 'switch0'
option vlan '1'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
list ports 'lan4'

config interface 'lan'
option device 'switch0.1'
[...]

I have taken this from an openwrt forum thread. It would be nice if we had a migration path and the new switch configuration properly documented since so far it has been hacks and guesswork

ezplanet:

A similar configuration to the above (for WRT32x) works also for an EA8300, however due to the latter having a legacy switch, the bridge eth0+eth1 (necessary to use all 5 ethernet ports in the same LAN in a repeater configuration), is quite cumbersome as I had to create a switch over an existing switch as follows to make it work:

config device
option type 'bridge'
option name 'switch1'
list ports 'eth0'
list ports 'eth1'
option mtu '1492'

config bridge-vlan
option device 'switch1'
option vlan '1'
list ports 'eth0'
list ports 'eth1'

config interface 'lan'
option device 'switch1.1'
option proto 'static'
option ipaddr 'x.x.x.x'
[...]

Fixed in the latest version
