Service Manual

• Display primary-secondary VLAN mapping.
EXEC mode or EXEC Privilege mode
show vlan private-vlan mapping
• Set the PVLAN mode of the selected port.
INTERFACE
switchport mode private-vlan {host | promiscuous | trunk}
NOTE: Secondary VLANs are Layer 2 VLANs, so even if they are operationally down while primary VLANs are
operationally up, Layer 3 trac is still transmitted across secondary VLANs.
NOTE: The outputs of the show arp and show vlan commands provide PVLAN data. For more information, refer to
the Dell Networking OS Command Line Reference Guide .
Conguration Task List
The following sections contain the procedures that congure a private VLAN.
• Creating PVLAN Ports
• Creating a Primary VLAN
• Creating a Community VLAN
• Creating an Isolated VLAN
Creating PVLAN ports
PVLAN ports are ports that will be assigned to the PVLAN.
1. Access INTERFACE mode for the port that you want to assign to a PVLAN.
CONFIGURATION mode
interface interface
2. Enable the port.
INTERFACE mode
no shutdown
3. Set the port in Layer 2 mode.
INTERFACE mode
switchport
4. Select the PVLAN mode.
INTERFACE mode
switchport mode private-vlan {host | promiscuous | trunk}
• host (isolated or community VLAN port)
• promiscuous (intra-VLAN communication port)
• trunk (inter-switch PVLAN hub port)
Example of the switchport mode private-vlan Command
For interface details, refer to Enabling a Physical Interface in the Interfaces chapter.
NOTE: You cannot add interfaces that are congured as PVLAN ports to regular VLANs. You also cannot add “regular”
ports (ports not congured as PVLAN ports) to PVLANs.
The following example shows the switchport mode private-vlan command on a port and on a port channel.
