To test this feature: ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 supervision 45 version 1 ip link set dev lan1 up ip link set dev lan2 up ip a add 192.168.0.1/24 dev hsr0 ip link set dev hsr0 up To remove HSR network device: ip link del hsr0 It is also possible to create another HSR interface, but it will only support HSR is software - e.g. ip link add name hsr1 type hsr slave1 lan3 slave2 lan4 supervision 45 version 1 Test HW: Two KSZ9477-EVB boards with HSR ports set to "Port1" and "Port2".
