Keen observers will have noticed that I pasted the output from the wrong vlan1.
The correct output is below.
vlan1: flags=8942<BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
ether 84:2b:2b:0b:b3:72
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect (1000baseT <full-duplex>)
status: active
vlan: 304 vlanpcp: 0 parent interface: bce0
groups: vlan
