airMAX - Pass VLAN Traffic as Tagged and Management as Untagged


Overview


Readers will learn how to pass management traffic as "untagged" and leave VLAN traffic "tagged", or more simply, pass traffic transparently through the airMAX radio.

NOTES & REQUIREMENTS: This article applies to both M and AC devices.

VLAN Configuration


Back to Top

The setup is pretty straightforward. Since you are not untagging VLANs on the radio and management ports are untagged, you will require a VLAN aware switch on both sides. Go to Network tab to make these configurations, use the screenshots below as examples. Click on either airMAX M or airMAX AC image to see it in large. Note that no changes have been made to the default bridge setup and no VLAN interfaces have been created, despite passing VLAN-tagged traffic.

Switch Perspective


Back to Top

For reference here is an example of what the switch port that is connected to the radio might look like. The Management VLAN is changed to VLAN100 and set to "U" (untagged) while all other non-Management VLANs would be set to "T" (tagged). If a VLAN shouldn't pass on the interface, set to "E" (exclude).
