What is private VLAN mode?

Private VLAN, also known as port isolation, is a technique in computer networking where a VLAN contains switch ports that are restricted such that they can only communicate with a given uplink. Each private VLAN typically contains many private ports, and a single uplink.

What are the private VLAN types?

There are two types of VLANs in Private VLANs:

  • Primary VLAN – All the ports in the private VLAN belong to a primary VLAN. A private VLAN can have only one primary VLAN.

How to configure promiscuous trunk port on Cisco Nexus 7000?

Promiscuous trunk—Beginning with Cisco NX-OS Release 5.0 (2) and Cisco DCNM Release 5.1 (1), on the Cisco Nexus 7000 Series devices, you can configure a promiscuous trunk port to carry traffic for multiple primary VLANs. You map the private VLAN primary VLAN and either all or selected associated VLANs to the promiscuous trunk port.

What is a VLAN interface in Cisco Nexus 7000?

By default, the VLANs are in the active state and pass traffic. A VLAN interface, or switched virtual interface (SVI), is a Layer 3 interface that is created to provide communication between VLANs.

Can a private VLAN be a layer 2 port?

Private VLANs provide additional protection at the Layer 2 level. A Layer 2 port can function as either a trunk port, an access port, or a private VLAN port. Beginning with Cisco NX-OS Release 5.0 (2), the system supports private VLAN promiscuous trunk ports and isolated trunk ports.

How many VLANs can I configure in promiscuous trunk port?

Each primary VLAN and one associated and secondary VLAN is a private VLAN pair, and you can configure a maximum of 16 private VLAN pairs on each promiscuous trunk port. Private VLAN promiscuous trunk ports carry traffic for normal VLANs as well as for primary private VLANs.
