No internet access as LACP bond

[bulowaty]

Hello,
I would like to ask for help.
I have Dell server with installed latest version of Proxmox VE and Cisco infrastructure.
I want to do LACP bonding between both ethernet interfaces.

I have ports on switch configured in this way:

interface Port-channel3
description SERVER
switchport mode trunk
lacp max-bundle 2
!
interface GigabitEthernet1/0/43
switchport trunk native vlan 601
switchport mode trunk
channel-protocol lacp
channel-group 3 mode active
!
interface GigabitEthernet1/0/44
switchport trunk native vlan 601
switchport mode trunk
channel-protocol lacp
channel-group 3 mode active
!

and /etc/network/interfaces looks like that

auto lo
iface lo inet loopback

auto eno3
iface eno3 inet manual

auto eno4
iface eno4 inet manual

auto bond0
iface bond0 inet manual
    bond_slaves eno3 eno4
    bond_miimon 100
    bond_mode 802.3ad
    bond_xmit_hash_policy layer2+3
   
auto vmbr0
iface vmbr0 inet static
    address 192.168.60.11
    netmask 255.255.255.128
    gateway 192.168.60.1
    bridge_ports bond0
    bridge_stp off
    bridge_fd 0
    bridge_vlan_aware yes
    bridge_vids 2-4094

iface eno1 inet manual

iface eno2 inet manual

The problem is that proxmox says the links are up, but on switch there are down so I have no internet access to the host.
Could you please let me know how to configure LACP between Cisco switches and Proxmox correctly?
I tried to use proxmox wiki, but there is bond0 on static mode so it requre to add address variable.

Ps. the machine has not internet access so I cannot install any other soft like ifenslave, ifconfig or openvswitch.
[edit] on switch ports are enabled but link is down

Thanks for help, regards Robert

bonding config seem to be ok on both side

can you send result of:

cat /proc/net/bonding/bond0

&&

ip addr

 

[bulowaty]

Of course.
ip addr


cat /proc/net/bonding/bond0

all seem fine.

Are you sure to see the link down on your cisco ? That's strange, because if lacp negociatation was failed, the link should be down in linux too.

interface Port-channel3
 description SERVER
 switchport trunk native vlan 601
 switchport mode trunk
 spanning-tree portfast disable
 lacp max-bundle 2
!

This is the solution. I forgot to put native vlan 601 on port-channel settings in switch. Thanks for reply!
