Hello,

here my Proxmox-Server config in switchport access mode (Dell switch):

Network is up

/etc/network/interface
auto lo
iface lo inet loopback
auto bond0
iface bond0 inet manual
bond-slaves eno1 eno2
bond-mode 802.3ad
bond-miimon 100
bond-lacp-rate 1
down /sbin/ip link set down dev $IFACE

auto vmbr301 # vlan 301 for Proxmox server
iface vmbr0 inet static
address xxxx
netmask 255.255.255.0
gateway xxxx
dns-nameservers xxx
dns-search xxxxx
bridge_ports bond0
bridge_stp off
mridge_maxwait 0
bridge_fd 0

iface vmbr301 inet6 static
address xxxx
netmask 64
gateway xxx
dns-nameserver xxxx
dns-search xxxxx
pre-up echo 0 > /proc/sys/net/ipv6/conf/$IFACE/autoconf


If i switch now to trunk mode, the network is not coming up!!

Dell switch config in trunk mode:
description "aaaaa bond0"
switchport mode trunk
switchport trunk allowed vlan 301-308,311-315,317-321,325-326

what do I have to do to make Proxmox run in tagged vlan mode?

regards
Hartmut
