Configuring Port VLAN Mapping on a Trunk Port

You can configure VLAN translation between the ingress (incoming) VLAN and a local (translated) VLAN
on a port. For the traffic arriving on the interface where VLAN translation is enabled, the incoming VLAN
is mapped to a translated VLAN that is VXLAN enabled.
On the underlay, this is mapped to a VNI, the inner dot1q is deleted, and switched over to the VXLAN network.
On the egress switch, the VNI is mapped to a translated VLAN. On the outgoing interface, where VLAN
translation is configured, the traffic is converted to the original VLAN and egress out. Refer to the VLAN
counters on the translated VLAN for the traffic counters and not on the ingress VLAN. Port VLAN (PV)
mapping is an access side feature and is supported with both multicast and ingress replication for flood and
learn and BGP EVPN mode for VXLAN.
Notes for Port VLAN Mapping:
• The ingress (incoming) VLAN does not need to be configured on the switch as a VLAN. The translated
• All Layer 2 source address learning and Layer 2 MAC destination lookup occurs on the translated VLAN.
• Port VLAN mapping is supported on Cisco Nexus 9300 Series switches. Beginning with Cisco NX-OS

VLAN needs to be configured and a vn-segment mapping given to it. An NVE interface with VNI
mapping is essential for the same.
Refer to the VLAN counters on the translated VLAN and not on the ingress (incoming) VLAN.
Release 7.0(3)I6(1), port VLAN mapping is supported on Cisco Nexus 9300-EX Series switches.
