Hello,

First time using Proxmox, also not extremely familiar with networking. I've been following youtube vids a lot to get me this far. I'm trying to get a server with dual NICs bonded with proxmox. Below are the relevant files/configs. The interfaces file is on proxmox and got mostly from a youtube vid https://www.youtube.com/watch?v=nIip66Rzt4I).

Below that is my cisco config. Mos of this is me guessing with trial and error. The second attempt was via video (https://www.youtube.com/watch?v=3J_CfskgBzU).

Either or, I cant get my proxmox connected to my linux machine. (not pictured in config) but my proxmox cant ping the gateway so I'm assuming its an issue with it and not between the linux machine and proxmox (at this point at least).

*The below is not copy and pasted, but form memory as I don't have it in front of me. So if there's a typo, it doesnt mean there is one in the actual config. (Not sayign there isnt one..). Also these are dummy IPs and not what I'm actually using, but the ones I'm using are viable and within parameters to work. (It all connected when using single NIC, but not when attempting to use a bond)

Any idea what I need to modify to make this work?

Proxmox /etc/network/interfaces file:

Code:
auto lo
iface lo inet loopback
iface enp0s25 inet manual
iface enp7s0 inet manual

auto bond0
iface bond0 inet manual
bond-slaves enp0s25 enp7s0
bond-miimon 100
bond-xmit-hash-policy layer2+3
bond-mode 802.3ad

auto vmbr0.100
iface vmbr0.100 inet static
address 10.10.10.10/27
gateway 10.10.10.1

auto vmbr0 iface vmbr0 inet manual
bridge-ports bond0
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4092

NOTE: lacp feature is enabled

Vlan 100 is the vlan for proxmox and 4092 is an unused vlan (the first YouTube vid said to set native to this..?)

cisco switch attempt 1:
Code:
vlan 100
description proxmox
no shutdown
ip address 10.10.10.1/27

vlan 4092
description unused
no shutdown

ethernet 1/1
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk native 4092
switchport trunk allowed vlan 100,4092

ethernet 1/2
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk native 4092
switchport trunk allowed vlan 100,4092


cisco attempt 2:
Code:
vlan 100
description proxmox
no shutdown
ip address 10.10.10.1/27

vlan 4092
description unused
no shutdown

port-channel 1
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk native 4092
switchport trunk allowed vlan 100,4092

ethernet 1/1
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk native 4092
switchport trunk allowed vlan 100,4092
channel group 1

ethernet 1/2
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk native 4092
switchport trunk allowed vlan 100,4092
channel group 1
