Private VLANs provide port-based security and isolation of local ports
contained within different private VLAN groups. This switch supports two
types of private VLANs – primary and community groups. A primary VLAN
contains promiscuous ports that can communicate with all other ports in
the associated private VLAN groups, while a community (or secondary)
VLAN contains community ports that can only communicate with other
hosts within the community VLAN and with any of the promiscuous ports in
the associated primary VLAN. The promiscuous ports are designed to
provide open access to an external network such as the Internet, while the
community ports provide restricted access to local users.
Multiple primary VLANs can be configured on this switch, and multiple
community VLANs can be associated with each primary VLAN. (Note that
private VLANs and normal VLANs can exist simultaneously within the same
switch.)
To configure primary/secondary associated groups, follow these steps:
1. Use the Configure VLAN (Add) page to designate one or more
community VLANs, and the primary VLAN that will channel traffic
outside of the VLAN groups.
2.
Use the Configure VLAN (Add Community VLAN) page to map a
community VLAN to the primary VLAN.
3.
Use the Configure Interface page to set the port type to promiscuous
(i.e., having access to all ports in the primary VLAN), or host (i.e.,
having access restricted to community VLAN members, and channeling
