What types are supported on private VLANs?

What types are supported on private VLANs?

There are three types of VLAN within a private VLAN:

  • Primary VLAN – it forwards the traffic from the promiscuous ports to isolated ports, community ports and other promiscuous ports in the same private VLAN.
  • Community VLAN – is a secondary VLAN.
  • Isolated VLAN – is a secondary VLAN.

What are operation modes of private VLANs?

An access port assigned to a private VLAN operates in one of two modes:

  • Host – The port inherits its behavior from the type of private VLAN it is assigned to.
  • Promiscuous – The port can communicate with any other private VLAN port in the same primary VLAN.

Can I use any VLAN ID?

VLANs are identified by a VLAN ID (a number between 0 – 4095), with the default VLAN on any network being VLAN 1. Each port on a switch or router can be assigned to be a member of a VLAN (i.e., to allow receiving and sending traffic on that VLAN).

What can be done with a private VLAN?

Generally, it is used for connecting switches with routers, Firewalls etc. An isolated port belongs to a secondary isolated VLAN.These are the host ports whose traffic is forwarded to the promiscuous port. A private VLAN allows only that traffic to the isolated port which is coming from its associated promiscuous port.

Which is port belongs to a private VLAN?

An isolated port belongs to a secondary isolated VLAN.These are the host ports whose traffic is forwarded to the promiscuous port. A private VLAN allows only that traffic to the isolated port which is coming from its associated promiscuous port. This port belongs to a secondary community VLAN.

Can a community VLAN communicate with a primary VLAN?

Community: Any switch ports associated with a common community VLAN can communicate with each other and with the primary VLAN but not with any other secondary VLAN. There can be multiple distinct community VLANs within one Private VLAN domain. There are mainly two types of ports in a Private VLAN: Promiscuous port (P-Port) and Host port.

Can a Promiscuous port communicate with a secondary VLAN?

In particular, a promiscuous port is a port that can communicate with all other private VLAN port types via the primary VLAN and any associated secondary VLANs, whereas isolated or community ports can communicate over their respective secondary VLANs only.
