Configuring Native 802.1Q Vlans On Private Vlans - Cisco nexus 5000 series Configuration Manual

Configuring Native 802.1Q VLANs on Private VLANs

This example shows how to add VLANs to the list of allowed VLANs on an Ethernet PVLAN trunk port:
switch# configure terminal
switch(config)# interface ethernet 1/3
switch(config-if)# switchport private-vlan trunk allowed vlan 15-20
Configuring Native 802.1Q VLANs on Private VLANs
Typically, you configure 802.1Q trunks with a native VLAN ID, which strips tagging from all packets on that
VLAN. This configuration allows untagged traffic and control traffic to transit the Cisco Nexus device.
Secondary VLANs cannot be configured with a native VLAN ID on promiscuous trunk ports. Primary VLANs
cannot be configured with a native VLAN ID on isolated trunk ports.
A trunk can carry the traffic of multiple VLANs. Traffic that belongs to the native VLAN is not encapsulated
Note
to transit the trunk. Traffic for other VLANs is encapsulated with tags that identify the VLAN that the
traffic belongs to.
Before You Begin
Ensure that the PVLAN feature is enabled.
