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.
