Extend PVLAN domain to another switch

This section describes how to extend a PVLAN domain to another switch.

To extend the primary and secondary VLANs to a connected device, add a regular switch port in Trunk mode to the VLANs of the PVLAN. The regular switch port in Trunk mode is also called an Inter-Switch Link (ISL) trunk port or PVLAN trunk.

Dell Technologies recommends that you do not configure the ISL as a promiscuous or secondary port.

NOTE:
  • For a regular switch port in Trunk mode, you must tag all VLANs of the PVLAN domain.
  • If you enable local proxy arp in the primary VLAN, both the host and the primary VLAN (as the local proxy) send an ARP reply.
  1. Enter Configuration mode. 
    OS10# configure terminal
  2. Enter Interface Configuration mode. 
    OS10(config)# interface ethernet 1/1/4
  3. Configure the Switchport mode as trunk for the port to carry more than single VLAN traffic. 
    OS10(conf-if-eth1/1/4)# switchport mode trunk
  4. Associate the port to be a trunk member of the primary and secondary VLANs. 
    OS10(conf-if-eth1/1/4)# switchport trunk allowed vlan 10
OS10(conf-if-eth1/1/4)# switchport trunk allowed vlan 20
OS10(conf-if-eth1/1/4)# switchport trunk allowed vlan 30
OS10# show vlan
