Private VLAN is designed as an extension of VLAN standard to add further segmentation of the logical broadcast domain. A regular VLAN is a single broadcast domain, whereas a private VLAN partitions a larger VLAN broadcast domain into smaller sub-domains. A sub-domain is represented by a pair of VLANs: a Primary VLAN and a - Secondary VLAN.

The original VLAN that is being divided into smaller groups is called Primary, + which implies that all VLAN pairs in a private VLAN share the same Primary VLAN. All the secondary VLANs exist only inside the Primary. Each Secondary VLAN has a specific VLAN ID associated to it, which differentiates one sub-domain from another.</para> <para>For further reading:</para> @@ -50,6 +72,9 @@ </listitem> </itemizedlist> </section> + <section id="ability-pvlan"> + <title>Prerequisites</title> + </section> <section id="prereq-pvlan"> <title>Prerequisites</title> <para>Ensure that you configure private VLAN on your physical switches out-of-band.</para>
