BONDING configurations issues

[e.satyavani]

Hi Team,

I am trying to configure the 4 node cluster, to have the HA availability I have used the bond mode as 802.3ad, but unable to see the ping response , on switch end also port-channel not came up due to the bonding configurations.



Here is the reference network interfaces configurations :

auto lo
iface lo inet loopback

iface eno1 inet manual

iface eno2 inet manual

auto bond0
iface bond0 inet manual
bond-slaves eno1 eno2
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer2+3

iface bond0.5 inet manual

auto vmbr0v5
iface vmbr0v5 inet static
address 10.10.10.2/24
gateway 10.10.10.1
bridge-ports bond0.5
bridge-stp off
bridge-fd 0

auto vmbr0
iface vmbr0 inet manual
bridge-ports bond0
bridge-stp off
bridge-fd 0

I'm a novice at Proxmox but I did see something about 802.3ad being split between two switches where you needed enterprise switches to allow this to work. Otherwise your bond needs to be on the same switch. I could be wrong here...

Yes, your correct. Please tell model and config of switch.
We're running such config with two Cisco Nexus 93xx and working well.
