For info Cisco trunks with a native VLAN, e.g.
interface SOMEPORT
switchport trunk encapsulation dot1q
switchport trunk native vlan R
switchport trunk allowed vlan R,S,T
switchport mode trunk
translates to
/interface bridge port
add bridge=bridge ingress-filtering=yes interface=PORTNAME pvid=R
/interface bridge vlan
add bridge=bridge tagged=…,PORTNAME,… vlan-ids=S
add bridge=bridge tagged=…,PORTNAME,… vlan-ids=T
and purely tagged trunks, e.g.
interface SOMEPORT
switchport trunk encapsulation dot1q
switchport trunk allowed vlan S,T
switchport mode trunk
translates to
/interface bridge port
add bridge=bridge frame-types=admit-only-vlan-tagged ingress-filtering=yes interface=PORTNAME
/interface bridge vlan
add bridge=bridge tagged=…,PORTNAME,… vlan-ids=S
add bridge=bridge tagged=…,PORTNAME,… vlan-ids=T
