Baystack-How to egress untagged frames on a Trunk port

[TLMsup]

Hi,

I've got several Baystack 450 and Baystack 325 switches and want to connect Wireless Access-Points.

SHORT QUESTION:
----------------
In order to manage the AP, I need to define a switch port on the Baystack that is both Tagged for a set of VLANs and untagged for the management VLAN. I haven't seen a way to do this. However it seems that this feature is required by the 802.1Q standard (see 8.11.2).

Detail EXPLAINATION:
--------------------
Since the Wireless Access-Points can affect several VLANs to my wireless clients, the port on which the Access-Point is connected to the Baystack is defined as a Trunk/Tagged port that belongs to a set of VLANs including users-vlans and the management-vlan.

The problem is that my Access-Point management interface can't be tagged: when the AP needs to communicate to the Radius Server, every frames is sent untagged. The AP waits for replies in untagged frames, but since the port is a Trunk port, replies come back tagged and are refused by the AP.

I really need a way to get the switch port egress untagged frames for the management VLAN while egressing tagged frames for al other vlans.

Thank you in advance.

What rev code are you running on the BS 450 ?

You're right I forgot to mention the versions:

* BS 325 is FW:3.5.0.2 and SW: 3.5.0.06
* BS 450 is FW:1.48 and SW: 4.5.1.2

Thank you.

I got the answer for my question from a Nortel engineer:

* This is an advanced functionality only available on some switches from the Baystack product line: for instance Baystack 470

* This functionality will never be developped on the Baystack 450

* But it will be available in a future firmware version on the Baystack 425 and 325. This new firmware should be released in Q4
