I've got a Debian Jessie server with two Intel i350 onboard 1Gbps NICs which I would like to bridge using 802.3ad protocol to my HP 1920G 48port managed switch.
Here is the kernel I'm running
~ % uname -a
Linux ltsp 4.9.0-0.bpo.3-amd64 #1 SMP Debian 4.9.30-2+deb9u5~bpo8+1 (2017-09-28) x86_64 GNU/Linux
I've setup the switch's LACP ports 3 & 4 for the 802.3ad, but when I try to connect my bonded network it complains that 'The ports configuration is improper for being attached'.
In my /etc/modules I have
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
loop
vhost_net
bonding
I've installed ifenslave
sudo apt install ifenslave-2.6
Here is the /etc/network/interfaces file
auto lo
iface lo inet loopback
# bond0 is the bonding NIC and can be used like any other normal NIC.
# bond0 is configured using static network information.
auto bond0
iface bond0 inet static
address 192.168.200.5
gateway 192.168.200.1
netmask 255.255.255.0
dns-nameservers 8.8.8.8
dns-search lan
# Use IEEE 802.3ad LACP bonding protocol
bond-mode 4
bond-miimon 100
bond-slaves none
#eth2 is manually configured, and slave to the “bond0” bonded NIC
allow_hotplug eth2
auto eth2
iface eth2 inet manual
bond-master bond0
bond-primary eth2
#eth3 ditto, thus creating a 2-link bond.
allow_hotplug eth3
auto eth3
iface eth3 inet manual
bond-master bond0
Which gives the output
~ % cat /proc/net/bonding/bond0

This doesn't work. I cannot ping this machine on 192.168.200.5. What am I missing here?
Update 23/08/2018
Tried setting bonding attributes in the modules file.
Edit /etc/modules
bonding mode=4 miimon=100 lacp_rate=1
Update 28/08/2018: more info from HP switch
display current-configuration in the HP command line gives me this output;

GigabitEthernet1/0/3 & GigabitEthernet1/0/4 are the ports I'm trying to bond. You can see that they are part of the link-aggregation group.
Update: Looking at the logfile
To check the logfile I had to do this through the web backend 'device -> syslog' and after restarting the network on my test bonding machine I got these four lines;
Aug 28 10:59:06:287 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/4 link status is UP.
Aug 28 10:58:56:005 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/3 link status is UP.
Aug 28 10:58:43:066 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/3 link status is DOWN.
Aug 28 10:58:33:338 2018 IFNET Error LINK_UPDOWN GigabitEthernet1/0/4 link status is DOWN.
