I set up a network bonding for failsafe in Ubuntu 18.04 according to this netplan:



network:
 version: 2
 ethernets:
 eno1:
 dhcp4: no
 enp2s0:
 dhcp4: no
 bonds:
 bond0:
 addresses: [192.168.3.5/24]
 gateway4: 192.168.3.253
 nameservers:
 addresses: [208.67.222.222,208.67.220.220,8.8.8.8,8.8.4.4]
 dhcp4: no
 interfaces:
 - eno1
 - enp2s0
 parameters:
 mode: active-backup
 primary: eno1


Now when I log in I get:



IP address for enp2s0: 192.168.3.96
IP address for eno1: 192.168.3.96
IP address for bond0: 192.168.3.5


and ifconfig gives me (abridged):



bond0: flags=5187<UP,BROADCAST,RUNNING,MASTER,MULTICAST> mtu 1500
 inet 192.168.3.5 netmask 255.255.255.0 broadcast 192.168.3.255
 inet6 xxx:a31d prefixlen 64 scopeid 0x20<link>
 ether xxx:a3:1d txqueuelen 1000 (Ethernet)

eno1: flags=6211<UP,BROADCAST,RUNNING,SLAVE,MULTICAST> mtu 1500

 ether xxx:a3:1d txqueuelen 1000 (Ethernet)


I am sure that, before the bond was set, one of the two MACs ended with :a3:1c



Did I make mistakes while setting the bond, or is this an intended behaviour?
