Is eth1 connected to your switch as trunk? If no (e.g. you have the same
settings for eth1 and eth2 on the switch side), then you can't tag it
inside your host.

To put it another way:
- start with known-good configuration, THEN make incremental changes
- in yout case, start by testing whether it works on the HOST side when you
assign an IP address to eth1.500, WITHOUT br0-500 bridge, and WITHOUT any
ip address assigned to eth2.
