Error while adding multiple ports in bridge

[Abhimnyu]

Hi i have proxmox node where i want to add multiple network ports in bridge, while adding the ports it work fine with three port but after adding fourth port the server network stops responding.

Adding 4 fiber ports in bridge first two ports from NIC-1 and other two ports are from NIC-2

checked by physical console bellow messages are found in "dmesg". Please suggest

[ 20.767539] vmbr0: received packet on enp94s0f1 with own address as source address (addr:34:80:0d:7d:5a:28, vlan:0)
[ 20.767541] vmbr0: received packet on enp94s0f0 with own address as source address (addr:34:80:0d:7d:5a:28, vlan:0)


This is my /etc/network/interfaces

auto vmbr0
iface vmbr0 inet static
address 192.168.0.20
netmask 255.255.255.0
gateway 192.168.0.1
bridge_ports enp24s0f0 enp24s0f1 enp94s0f0 enp94s0f1
bridge_stp off
bridge_fd 0


Thank you.

Where do the ports connect to?
What do you want to achieve?
Would a bond possibly be the way to go?

are you sure that you don't have a network loop ? you should use a bond.

Thanks for your quick reply.

1. These pors are connected to the switch.
2. I want to use one IP for all four network port it's for HA
3. Bond can be possibly way to go but I don't know how ?

Can I use bond in vmbr0 without configuring vlan ?

Well, in that case you need to use a bond because now you created, as @spirit mentioned, a loop.
You can select the bond interface as bridge port for the vmbr.

Make sure to select a bond mode that your switch supports.
Do you have one or two switches? Two stacked switches would be needed to not have a single point of failure there.

Thank you arron,

Yes i have two switches. i have configured the Bond and Bridge as bellow & it worked for me.

auto bond0
iface bond0 inet manual
slaves enp24s0f0 enp24s0f1 enp94s0f0 enp94s0f1
bond_miimon 100
bond_mode 802.3ad
bond_xmit_hash_policy layer2+3
