When a full bonding configuration is made with systemd in /etc/systemd/network, on 2 two differents physical hosts, same hardware and in same VLAN: ----- bond0.netdev ------ [NetDev] Name=bond0 Kind=bond [Bond] Mode=802.3ad TransmitHashPolicy=layer3+4 MIIMonitorSec=100ms LACPTransmitRate=fast ----- vlan3147.netdev ------ [NetDev] Name=vlan3147 Kind=vlan [VLAN] Id=3147 ----- bond0.network ------ [Match] Name=bond0 [Network] VLAN=vlan3147 BindCarrier=enp1s0f1 enp1s0f0 LinkLocalAddressing=no ----- enp1s0f0.network ------ [Match] Name=enp1s0f0 [Network] Bond=bond0 ----- enp1s0f1.network ------ [Match] Name=enp1s0f1 [Network] Bond=bond0 ----- vlan3147.network ------ [Match] Name=vlan3147 [Address] Address=**masked ip***/25 [Route] Destination=10.0.0.0/8 Gateway=**masked ip*** [Route] Destination=**masked ip***/16 Gateway=**masked ip*** And in /etc/modprobe.d/bonding.conf options bonding max_bonds=0 ..... the two different physicals hosts have the same MAC address on bonding: on host A: 32: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 16:d6:b0:24:16:3b brd ff:ff:ff:ff:ff:ff on host B: 32: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 16:d6:b0:24:16:3b brd ff:ff:ff:ff:ff:ff So strange... how the MAC is generated ? There is no relevant rules in /etc/udev/rules.d/70-persistent-net.rules to explain it, and issue occurs only with systemd-network, *NOT* with legacy configuration /etc/network/interfaces.
