Native VLAN Dot11Radio Interface

Hi all,

Probably a very simple question...

Is it true that I only need to create a dot11radio interface for corresponding wireless VLANs and not management addresses.

The reason i ask, on most access points i have seen and not configured myself, if for example, the AP is using VLAN2 as its native VLAN which is trunked to a switch, there has always been a corresponding radio interface for the native vlan which i don't think is correct.

When i remove this radiointerface, the AP complains a bit but it doesn't cause any issues.

I guess having this radiointerface doesn't cause any issues too as its not mapped to a VLAN within the dott1radio0 interface.

Just looking for best practices really!

Many thanks

Paddy

Update

-------

When you create a VLAN using the HTTP interface it creates the corresponding radio interface automatically.

I've been using the CLI to configure my APs as i'm a real techie 😉 so i've not been creating radio interfaces unless they are needed i.e. my management vlan doesn't need a radio interface

Thanks and sorry for such a pony question!

virtual dot11 radio interface is used for communication to other infrastructure devices, like repeater, workgroup bridges, and non-root bridges (not apply to to AP). When there is an infrastructure device associates, the virtual dot11 radio interface is brought up. When all infrastructure devices disassociate, the virtual dot11 radio interface is brought down.

As there is no easy way to add or delete interface in IOS, we always create a virtual dot11 radio interface right after it boots up or a VLAN is created. This is working by design.

Thanks Dixon, this makes sense
