I need everything I can on vlans over wireless 802.11b connetions thanks So long and thanks for all the fish.

Wow, that's a huge question; or two. I'd try the IEEE website if you want to read the spec sheet on the 802.11b wireless protocol (something like 11Mbps), but the VLAN thing is another matter. Can you be more specific? What is it you are trying to do that's not working over your wireless connection?

 

[gunthnp]

well what need to no is if 802.11b wireless brige can understand vlan.

ok when a vlan paket is sent it adds vlan info to the header right before the mac address when it hit the wireless (802.11b)brige will it strip it and and loss the the vlan info and the mac address or can it read the vlan info and mac address and send it on it way So long and thanks for all the fish.

VLANs don't alter the packets or headers going through a network. Let's see... you want to add a wireless network to a network VLAN? Is that what you're trying to do? Well... consider the wireless AP (Access Point) as a bridge. Add the AP's port to your VLAN and now all the members of your wireless network are part of your VLAN.

To get from one VLAN to another, don't forget -- you need a router. Maybe you want to give use more information on what you are trying to do...?

ok I work a school we have a 3640 ciso router linking the vlans and all ready have wireless boxs linking the schools but I need to set up district wide vlans and so I need to I make sure that vlan info can be understod by the wireless boxs So long and thanks for all the fish.

Ok, gunthnp... I see... you're doing the nice frame tagging type of VLAN 802.10 stuff... the 'real stuff'... in that case there is the VLAN ID stuff packed into those packets.

The switches on the outside of the VLAN core will spit out the packets in the native Ethernet II frame format (assuming you're talking about IP over Ethernet II frames). The Access Points hooked onto your Ethernet network can understand that frame format and will alter the header from the Ethernet header structure to the 802.11 structure. [see

]

But... it sounds like you want to know if your Access Points can understand the 802.10 VLAN frame formats and be part of the VLAN switching process directly...? I don't know about that... think they must be 'one off' to receive standard Ethernet frames.

<-- there's a school with wireless VLANs and the Cisco 3600 dial access stuff.

Cool!

thanks that was what is was looking for. So long and thanks for all the fish.
