vlans

sudo ip link add link eno1 name eno1.52 type vlan id 52
sudo ip link add link eno1 name eno1.52 type vlan id 52
sudo ip link set dev eno1.52 up
sudo ip addr add 192.168.52.2/24 brd 192.168.52.255 dev eno1.52
ping 192.168.52.1 # this would be firewall or other host see line below
sudo tcpdump -nnei eno1 -vvv | grep "vlan 52"
sudo tcpdump -i eno1 vlan 52

use same but on other host (ie firewall)

sudo ip addr add 192.168.52.1/24 brd 192.168.52.255 dev eno1.52

on cisco

this setups a trunk native vlan is 1 for untagged and default allows all vlans

portfast might not be the best idea if you don't know what you are doing

conf t
int vlan 52
exit
interface GigabitEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk
 spanning-tree portfast trunk

you might also use these for link agg (LACP)

interface Port-channel1
channel-group 1 mode active

Trouble shooting

Cisco

sh int trunk
sh lacp neighbor

If you make changes you might need to do a shut/no shut on range of interfaces you are using.

Linux

cat /proc/net/bonding/bond0
