Using the Private VLAN Commands

To use the PVLAN feature, use the following commands.

  • Enable/disable Layer 3 communication between secondary VLANs. INTERFACE VLAN mode [no] ip local-proxy-arp
    • NOTE: Even after you disable ip-local-proxy-arp ( no ip-local-proxy-arp) in a secondary VLAN, Layer 3 communication may happen between some secondary VLAN hosts, until the address resolution protocol (ARP) timeout happens on those secondary VLAN hosts.
  • Set the mode of the selected VLAN to community, isolated, or primary. INTERFACE VLAN mode [no] private-vlan mode {community | isolated | primary}
  • Map secondary VLANs to the selected primary VLAN. INTERFACE VLAN mode [no] private-vlan mapping secondary-vlan vlan-list
  • Display type and status of PVLAN interfaces. EXEC mode or EXEC Privilege mode show interfaces private-vlan [interface interface]
  • Display PVLANs and/or interfaces that are part of a PVLAN. EXEC mode or EXEC Privilege mode show vlan private-vlan [community | interface | isolated | primary | primary_vlan | interface interface]
  • 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 traffic is still transmitted across secondary VLANs.
  • NOTE: The outputs of the show arp and show vlan commands are augmented in the Dell Networking OS version 7.8.1.0 to provide PVLAN data. For more information, refer to the Dell Networking OS Command Line Reference Guide .
