Checking the MAC address table on a virtual switch
As the devices connected to the virtual Network start to communicate with each other, the virtual switch on the Compute node learns the MAC addresses of the network interfaces. In this recipe, we will learn how to view the MAC address table of a virtual switch on an OpenStack Compute node.
Getting ready
For this recipe, you will require the following information:
- SSH-based login credentials for the Compute node
How to do it…
