Vlan translation Nexus 9300

[Pascal Lacroix]

Hi,

is it possible to do a one to one vlan translation on a Nexus 9300? The Nexus is running in NX-OS mode and VXLAN is not enabled.

With the switch port vlan mapping command i get a warning message:

hostname(config-if)# switchport vlan mapping 10 20
Warning: Eth1/37 : VLAN translation is only supported on vxlan enabled vlans

Is it possible to use the command below or is there another way to do the vlan mapping?

interface Ethernet1/37
switchport vlan mapping 10 dot1q-tunnel 10

kind regards,

Pascal

not sure what nexus code you are using, look at the document

NX-OS version is 9.3(6)

the solution for this is to enable VXLAN on the vlan that needs to be translated. I have tested this with the config below and that works:

feature nv overlay
feature vn-segment-vlan-based

vlan 750
vn-segment 750

interface Ethernet1/1
switchport
switchport mode trunk
switchport vlan mapping enable
switchport vlan mapping 700 750
switchport trunk allowed vlan 750
