Dell Configuration Guide for the S4048–ON System 9.14.2.5

Creating a Primary VLAN

A primary VLAN is a port-based VLAN that is specifically enabled as a primary VLAN to contain the promiscuous ports and PVLAN trunk ports for the private VLAN.

1. Access INTERFACE VLAN mode for the VLAN to which you want to assign the PVLAN interfaces.
   CONFIGURATION mode
   interface vlan vlan-id
2. Enable the VLAN.
   INTERFACE VLAN mode
   no shutdown
3. Set the PVLAN mode of the selected VLAN to primary.
   INTERFACE VLAN mode
   private-vlan mode primary
4. Map secondary VLANs to the selected primary VLAN.
   INTERFACE VLAN mode
   private-vlan mapping secondary-vlan vlan-list
   The list of secondary VLANs can be:

   • Specified in comma-delimited (VLAN-ID,VLAN-ID) or hyphenated-range format (VLAN-ID-VLAN-ID).
   • Specified with this command even before they have been created.
   • Amended by specifying the new secondary VLAN to be added to the list.
5. Add promiscuous ports as tagged or untagged interfaces.
   INTERFACE VLAN mode
   tagged interface or untagged interface
   Add PVLAN trunk ports to the VLAN only as tagged interfaces.
   You can enter interfaces in numeric or in range format, either comma-delimited (slot/port,port,port) or hyphenated (slot/port-port).
   You can only add promiscuous ports or PVLAN trunk ports to the PVLAN (no host or regular ports).
6. (OPTIONAL) Assign an IP address to the VLAN.
   INTERFACE VLAN mode
   ip address ip address
7. (OPTIONAL) Enable/disable Layer 3 communication between secondary VLANs.
   INTERFACE VLAN mode
   ip local-proxy-arp
