Una volta configurato lo switch HP 1820-24G Switch J9980A per avere il port trunking tra le porte selezionate ed eventualmente aver assegnato il trunk alla VLAN si passa alla configurazione del sistema.
Attenzione che HP chiama Trunk dinamico la modalità LACP.

Ho trovato in alcuni howto questa specifica.
Male non dovrebbe fare.

echo "mii" >> /etc/modules

Si passa alla configurazione dell file /etc/network/interfaces in questo modo.

auto lo
iface lo inet loopback
iface enp2s0f0 inet manual
        post-up ifconfig enp2s0f0 txqueuelen 5000 && ifconfig enp2s0f0 mtu 9000
iface enp2s0f1 inet manual
        post-up ifconfig enp2s0f1 txqueuelen 5000 && ifconfig enp2s0f1 mtu 9000
auto bond0
iface bond0 inet manual
        bond-slaves enp2s0f0 enp2s0f1
        bond-mode 802.3ad
        bond-miimon 100
        bond-downdelay 200
        bond-updelay 200
        bond-lacp-rate 1
        bond-xmit-hash-policy layer2+3
        post-up ifconfig bond0 mtu 9000 && ifconfig bond0 txqueuelen 5000
auto vmbr0
iface vmbr0 inet static
        address  172.16.5.10
        netmask  255.255.255.0
        bridge_ports bond0
        bridge_stp off
        bridge_fd 0
        post-up ifconfig vmbr0 mtu 9000 && ifconfig vmbr0 txqueuelen 5000

A questo punto dopo il riavvio il Bond/Trunk risulterà attivo.
