VLAN subinterfaces is a traditional way of VLAN configuration in Linux. This approach requires configuration of IP address on each subinterface to work with UPDv4 transport The new transport however is intended for a different configuration model - VLAN aware bridges with many interfaces and the VLAN devices on top of the bridge. Here is an example how to configure it: ip link add name br0 type bridge ip link set dev br0 type bridge vlan_filtering 1 ip link set dev br0 up ip link set dev eth1 master br0 ip link set dev eth2 master br0 bridge vlan add vid 20 dev eth1 bridge vlan add vid 20 dev eth2 bridge vlan add vid 30 dev eth1 bridge vlan add vid 20 dev br0 self bridge vlan add vid 30 dev br0 self ip link add link br0 name br0.20 type vlan id 20 ip link add link br0 name br0.30 type vlan id 30 ip addr add 192.168.20.1 dev br0.20 ip addr add 192.168.30.1 dev br0.30 ip link set dev br0.20 up ip link set dev br0.30 up PTP4L configuration file: [eth1@20] vlan 20 vlan_intf br0.20 delay_mechanism E2E network_transport RAWUDPv4 [eth1@30] vlan 30 vlan_intf br0.30 delay_mechanism E2E network_transport RAWUDPv4 [eth2@20] vlan 20 vlan_intf br0.20 delay_mechanism E2E network_transport RAWUDPv4 Thanks, Andriy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
