own community VLAN, and with their designated promiscuous ports. (Note that
private VLANs and normal VLANs can exist simultaneously within the same switch.)
Figure 2-35. Promiscuous and Community VLAN Ports
Each private VLAN consists of two components: a primary VLAN and one or more
community VLANs. A primary VLAN allows traffic to pass between promiscuous
ports, and between promiscuous ports and community ports subordinate to the
primary VLAN. A community VLAN conveys traffic between community ports, and
from the community ports to their associated promiscuous ports. Multiple primary
VLANs can be configured on this switch, and multiple community VLANs can be
configured within each primary VLAN.
To configure private VLANs, follow these steps:
1. Use the Private VLAN Configuration menu (page 2-57) to designate one or more
community VLANs and the primary VLAN that will channel traffic outside of the
community groups.
2. Use the Private VLAN Association menu (page 2-58) to map the secondary (i.e.,
community) VLAN(s) to the primary VLAN.
3. Use the Private VLAN Port Configuration menu (page 2-60) 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 all other
traffic through a promiscuous port). Then assign any promiscuous ports to a
primary VLAN and any host ports a secondary VLAN (i.e., community VLAN).
Displaying Current Private VLANs
The Private VLAN Information page displays information on the private VLANs
configured on the switch, including primary and community VLANs, and their
associated interfaces.
Command Attributes
• VLAN ID – ID of configured VLAN (1-4093, no leading zeroes).
• Primary VLAN – The primary VLAN with which the selected VLAN is associated.
(Note that this displays as VLAN 0 if the selected VLAN is itself a primary VLAN.)
