Hello, I've tried with 240-4, the VLAN problem is still present.
File /etc/systemd/network/00-xgbe1.link : [Match] MACAddress=00:50:56:96:0d:d7 [Link] Name=xgbe1 File /etc/network/interfaces : iface xgbe1.40 inet static address 192.168.40.218/24 $ sudo ifup xgbe1.40 Cannot find device "xgbe1.40" ifup: failed to bring up xgbe1.40 $ sudo dmesg [...] [ 56.261847] vmxnet3 0000:13:00.0 xgbe1: intr type 3, mode 0, 3 vectors allocated [ 56.263559] vmxnet3 0000:13:00.0 xgbe1: NIC Link is Up 10000 Mbps [ 56.446638] 8021q: 802.1Q VLAN Support v1.8 [ 56.446861] 8021q: adding VLAN 0 to HW filter on device xgbe1 [ 56.449675] rename5: renamed from xgbe1.40 $ ip link 3: xgbe1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 00:50:56:96:0d:d7 brd ff:ff:ff:ff:ff:ff 5: rename5@xgbe1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 00:50:56:96:0d:d7 brd ff:ff:ff:ff:ff:ff The device xgbe1.40 is created and renamed during ifup to "rename5@xgbe1". If you think the problem is not the same as mentioned earlier, I can open a new bug report. Best regards. -- * *Emmanuel DECAEN
