esnode9: one interface of the bonding is off or degraded

On esnode9 one of the bonding's two interfaces was off:

root@esnode9:~# ip link show ens21f1np1
3: ens21f1np1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 6c:92:cf:cc:9d:c7 brd ff:ff:ff:ff:ff:ff
    altname enp200s0f1np1
root@esnode9:~# networkctl
IDX LINK       TYPE     OPERATIONAL SETUP
  1 lo         loopback carrier     unmanaged
  2 ens21f0np0 ether    enslaved    configured
  3 ens21f1np1 ether    off         unmanaged
  4 bond0      bond     carrier     configured
  5 vlan440    vlan     routable    configured

after switching it on, it appears degraded:

root@esnode9:~# ip link set ens21f1np1 up
root@esnode9:~# ip a s ens21f1np1
3: ens21f1np1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

It seems one of the systemd configuration file is incorrect:

root@esnode9:~# cat /etc/systemd/network/bond0-interfaces.network
[Match]
Name=ens21f0np0
Name=ens21f0np0

[Network]
Bond=bond0

added activity::MRO label

Right, according to the ipxe setup, it should be:

PRESEED_INTERFACE0: ens21f0np0
PRESEED_INTERFACE1: ens21f1np1

After fixing the interfaces name in the bonding declaration, restarting networking service has no effect so I rebooted the node and all the network interfaces are correct:

root@esnode9:~# cat /etc/systemd/network/bond0-interfaces.network 
[Match]
Name=ens21f0np0
Name=ens21f1np1

[Network]
Bond=bond0
root@esnode9:~# ip a s ens21f1np1
3: ens21f1np1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP group default qlen 1000
