Private VLAN Configuration Task List
The following sections contain the procedures that configure a PVLAN:
• Creating PVLAN Ports
• Creating a Primary VLAN
• Creating a Community VLAN
• Creating an Isolated VLAN
Creating PVLAN Ports
PVLAN ports are those that are assigned to the Private VLAN. To assign PVLAN ports, follow these steps:
For interface details, refer to Enable a Physical Interface in Interfaces.
Figure 38-1 shows the use of the
switchport mode private-vlan command on a port and on a port channel.
Figure 38-1. switchport mode private-vlan Command Example
Step Command Syntax Command Mode Purpose
1
interface interface
CONFIGURATION Access INTERFACE mode for the port that you want to assign
to a PVLAN.
2
no shutdown
INTERFACE Enable the port.
3
switchport
INTERFACE Set the port in Layer 2 mode.
4
switchport mode
private-vlan
{host |
promiscuous | trunk
}
INTERFACE Select the PVLAN mode:
•
host (port in isolated or community VLAN)
•
promiscuous (intra-VLAN communication port)
•
trunk (inter-switch PVLAN hub port)
Note: Interfaces that are configured as PVLAN ports cannot be added to regular VLANs. Conversely,
“regular” ports (ports not configured as PVLAN ports) cannot be added to PVLANs.
