Getting 802.1Q VLANs to work with VMWare

gistfile1.txt

Here’s how to create multiple VLANs on a Linux machine running on a VMWare server. I did this to run arpwatch to monitor IP conflicts on our LAN. Be sure not to send any traffic out these interfaces unless you intend it to broadcast to all attached NICs.

In VMWare:
1) Click on the server root node, and choose the Configuration tab
2) Select the properties for the NIC that you want to use VLAN tagging on
3) Select Edit to enable Promiscuous Mode

Then in Linux:

4)

# First bring up interface
ip link set eth1 up
# Add VLAN tagged interfaces
ip link add link eth1 name vlan6 type vlan id 6
ip link set vlan6 up
ip link add link eth1 name vlan22 type vlan id 22
ip link set vlan22 up
ip link add link eth1 name vlan23 type vlan id 23
ip link set vlan23 up
