Hi,
I am getting started with proxmox so apologies in advanced for the basic questions but was wondering if someone could help guide me in the right direction.

  1. How can I enable lacp-fast
  2. How can I enabled jumbo frames (various post show different methods)
    e.g. pre-up ip link set eth0 mtu 9000 && ip link set eth1 mtu 9000 && ip link set bond0 mtu 9000
  3. What is the correct procedure for editing /etc/networking/interfaces as the config file states
  4. Will the changes break the WebUI network view?
"
Code:
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Background
  • 2x 10GbE -> Data Network
  • 2x 10GbE -> Storage Network
  • Switch - Arista 7050S with MLAG
  • Just using bonds and bridge no ovs
Thank you in advance!
 
ok, so I got jumbo frames working now and the lacp fast but just wanted to make sure its okay to configure as below.
Code:
auto bond0
iface bond0 inet manual
    bond-slaves eno1 enp3s0f0
    bond-miimon 100
    bond-mode 802.3ad
    bond-xmit-hash-policy layer2+3
    bond-lacp-rate 1
#Data Network

auto bond1
iface bond1 inet manual
    bond-slaves eno2 enp3s0f1
    bond-miimon 100
    bond-mode 802.3ad
    bond-xmit-hash-policy layer2
    bond-lacp-rate 1
    mtu 9000
#Storage Network

auto vmbr0
iface vmbr0 inet static
    address  10.11.4.12
    netmask  255.255.0.0
    gateway  10.11.0.1
    bridge-ports bond0.101
    bridge-stp off
    bridge-fd 0
#101_internal_vlan

auto vmbr1
iface vmbr1 inet static
    address  172.19.19.112
    netmask  255.255.255.0
    bridge-ports bond1.1000
    bridge-stp off
    bridge-fd 0
    pre-up ip link set bond1.1000 mtu 9000
#1000_storage
