Hello!
I have a Cisco WS-C4948E and a Proxmox server.
I configured LACP on cisco using the following commands:
```
interface Port-channel 2
switchport
switchport mode access
switchport access vlan 1000
service-policy input RATE-LIMIT
service-policy output RATE-LIMIT
!
interface range GigabitEthernet1/21 - GigabitEthernet1/24
shutdown
no shutdown
switchport
no service-policy input RATE-LIMIT
no service-policy output RATE-LIMIT
channel-group 2 mode active
```
on Proxmox I have the following network interface file:
```
auto lo
iface lo inet loopback
iface eno1 inet manual
iface eno2 inet manual
iface eno3 inet manual
iface eno4 inet manual
auto bond0
iface bond0 inet static
bond-slaves eno1 eno2 eno3 eno4
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer2+3
auto vmbr0
iface vmbr0 inet static
address 188.XXX.YYY.249/24
gateway 188.XXX.YYY.1
bridge-ports bond0
bridge-stp off
bridge-fd 0
up ip addr add 192.168.1.249/24 dev $IFACE label $IFACE:0
down ip addr del 192.168.1.249/24 dev $IFACE label $IFACE:0
iface vmbr0 inet6 static
address 2a0e:8f02:XXXX::f0f9/64
gateway 2a0e:8f02:XXXX::1
iface idrac inet manual
```
Why I have network issues (connection reset) and many MACs assigned to 192.168.1.249?

I have a Cisco WS-C4948E and a Proxmox server.
I configured LACP on cisco using the following commands:
```
interface Port-channel 2
switchport
switchport mode access
switchport access vlan 1000
service-policy input RATE-LIMIT
service-policy output RATE-LIMIT
!
interface range GigabitEthernet1/21 - GigabitEthernet1/24
shutdown
no shutdown
switchport
no service-policy input RATE-LIMIT
no service-policy output RATE-LIMIT
channel-group 2 mode active
```
on Proxmox I have the following network interface file:
```
auto lo

Why I have network issues (connection reset) and many MACs assigned to 192.168.1.249?
