When everything is configured, VLAN membership on the bridge in this
selftest are as follows:
# bridge vlan show
port vlan-id
swp2 1 PVID Egress Untagged
555
br1 1 Egress Untagged
555 PVID Egress Untagged
Note that it is possible for untagged traffic to just flow through as VLAN
1, instead of using VLAN 555 as intended by the test. This configuration
seems too close to "works by accident", and it would be better to just shut
out VLAN 1 altogether.
To that end, configure vlan_default_pvid of 0:
# bridge vlan show
port vlan-id
swp2 555
br1 555 PVID Egress Untagged
