# vlans<br />
<br />
```<br />
sudo ip link add link eno1 name eno1.52 type vlan id 52<br />
sudo ip link add link eno1 name eno1.52 type vlan id 52<br />
sudo ip link set dev eno1.52 up<br />
sudo ip addr add 192.168.52.2/24 brd 192.168.52.255 dev eno1.52<br />
ping 192.168.52.1 # this would be firewall or other host see line below<br />
sudo tcpdump -nnei eno1 -vvv | grep "vlan 52"<br />
sudo tcpdump -i eno1 vlan 52<br />
```<br />
<br />
use same but on other host (ie firewall)<br />
```<br />
sudo ip addr add 192.168.52.1/24 brd 192.168.52.255 dev eno1.52<br />
```<br />
<br />
## on cisco<br />
<br />
this setups a trunk native vlan is 1 for untagged and default allows all vlans <br />
<br />
portfast might not be the best idea if you don't know what you are doing<br />
```<br />
conf t<br />
int vlan 52<br />
exit<br />
interface GigabitEthernet0/1<br />
switchport trunk encapsulation dot1q<br />
switchport mode trunk<br />
spanning-tree portfast trunk<br />
```<br />
<br />
you might also use these for link agg (LACP)<br />
```<br />
interface Port-channel1<br />
channel-group 1 mode active<br />
```<br />
<br />
# Trouble shooting<br />
<br />
## Cisco<br />
<br />
```<br />
sh int trunk<br />
sh lacp neighbor<br />
```<br />
<br />
If you make changes you might need to do a shut/no shut on range of interfaces you are using.<br />
<br />
## Linux<br />
<br />
```<br />
cat /proc/net/bonding/bond0<br />
```<br />
