I recently upgraded from 19.07 to 21.02.1 on my WRT3200ACM.
There are a couple of problems I am tracking.
One of them is the missing VLAN and switch config from my previous settings.
Below are the previous network settings, I had port mirroring activated.
I understand port mirroring has changed in the new release.
Is VLAN and switch configuration still possible in LUCI?
config switch option name 'switch0' option reset '1' option enable_vlan '1' option mirror_monitor_port '0' option enable_mirror_rx '1' option enable_mirror_tx '1' option mirror_source_port '6' config switch_vlan option device 'switch0' option vlan '1' option ports '0 1 2 3 5t' option vid '1' config switch_vlan option device 'switch0' option vlan '2' option ports '4 6t' option vid '2'
