Open Vswitch is an Open Source software switch designed specifically to be used in virtualized environments such as OpenStack or RHEV-H. OVS (Open Vswitch) was designed to make it easier to manage, configure, and monitor virtual traffic within a virtualized environment.
Below, is Part 1 in what I suspect will be a multiple part series on configuring, viewing, and managing your virtualized network via OVS.
Viewing OVS Bridges
To view OVS Bridges configured on a system, use the command ovs-vsctl as shown below. On my test system, we have three configured bridges; br-ex, br-int, and br-tun.
# ovs-vsctl show
The output from the command above is rather verbose. If you prefer a more terse output you best try the command below. In this instance the only output is the name of our bridges.
