4.4.24 Private VLAN
4.4.24.1 Configuration
Use the Private VLAN Configuration page to add Virtual Local Area Networks
(VLANs) to the device and to configure existing VLANs as private VLANs. Private
VLANs provide Layer 2 isolation between ports that share the same broadcast
domain. In other words, a private VLAN allows a VLAN broadcast domain to be parti-
tioned into smaller point-to-multipoint subdomains. The ports participating in a private
VLAN can be located anywhere in the Layer 2 network. Each subdomain is defined
(represented) by a primary VLAN and a secondary VLAN. The primary VLAN ID is
the same for all subdomains that belong to a private VLAN. The secondary VLAN ID
differentiates subdomains from each another and provides Layer 2 isolation between
ports that are members of the same private VLAN.
VLAN The VLAN ID associated with the PBVLAN. Untagged traffic that
matches the protocol criteria is tagged with this VLAN ID.
Protocol The protocol or protocols to use as the match criteria to determine
whether a particular packet belongs to the PBVLAN. The protocols in
this list are checked against the two-byte EtherType field of ingress
Ethernet frames on the PVBLAN Group Interfaces. When adding a
protocol, you can specify the EtherType hex value or (for IP, ARP, and
IPX) the protocol keyword.
To configure the protocols associated with a PBVLAN group, use the
buttons available in the protocol table:

To add a protocol to the group, click button and enter the
protocol to add.

To delete an entry from the list, click button associated with
the entry to remove.

To delete all entries from the list, click button in the heading
row.
Available Interfaces The interfaces that can be added to the PBVLAN group. An interface
can be a member of multiple groups as long as the same protocol is
not specified in more than one group that includes the interface. To
move an interface between the Available Interfaces and Group Inter-
faces fields, click the interface (or CTRL + click to select multiple inter-
faces), and then click the appropriate arrow to move the selected
interfaces to the desired field.
Group Interfaces The interfaces that are members of the PBVLAN group.

Note! The default VLAN and management VLAN are not displayed on the
page because they cannot be configured as private VLANs.
