VLANS and Multiple SSID Question

I have the 1230 series AP's in my infrastructure with 3500 series switches that are trunked together via 802.1q the AP's have a 192.168.199.x address assigned to them all on a seperate vlan from the wired traffic and internal IP scheme.

What I would like to also do is create another vlan and introduce DSL to it so if guests etc can connect to WLAN/Internet they can do so through this other vlan and SSID however - How can I do that if those AP's are already on a diffrent vlan to seperate the internal network infrastructure? I do not think I can configure multi Vlan on a port cause the switch is involved in trunking. Any clues? Amd I correct?

Do I need to totally rethink this or is the another solution?

I hope I was clear

Re: VLANS and Multiple SSID Question

Hi Pete,

Have a read of these docs, this should help you on your way;

Cisco Aironet 1200 Series

Wireless Virtual LAN Deployment Guide

From this doc;

Wireless, LAN (WLAN)

VLANs on Aironet Access Points Configuration Example

From this doc;

Using VLANs with Cisco Aironet Wireless Equipment

From this doc;

Configuring Multiple SSIDs

From this doc;

Understanding Multiple SSIDs

The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access points on a network or sub-network can use the same SSIDs. SSIDs are case sensitive and can contain up to 32 alphanumeric characters. Do not include spaces in your SSIDs.

You can configure up to 16 SSIDs on your 1200 series access point and assign different configuration settings to each SSID. All the SSIDs are active at the same time; that is, client devices can associate to the access point using any of the SSIDs. These are the settings you can assign to each SSID:


•Client authentication method

•Maximum number of client associations using the SSID

•RADIUS accounting for traffic using the SSID

•Guest mode

•Repeater mode, including authentication username and password

•Redirection of packets received from client devices

If you want the access point to allow associations from client devices that do not specify an SSID in their configurations, you can set up a guest SSID. The access point includes the guest SSID in its beacon.

If your access point will be a repeater or will be a root access point that acts as a parent for a repeater, you can set up an SSID for use in repeater mode. You can assign an authentication username and password to the repeater-mode SSID to allow the repeater to authenticate to your network like a client device.

If your network uses VLANs, you can assign one SSID to a VLAN, and client devices using the SSID are grouped in that VLAN.

Hope this helps!

Re: VLANS and Multiple SSID Question

Great documentation. I just wanted to throw out there that I have 2 different networks I want to have 2 different SSID'S on. one from a dsl source where I will make it wide open for guests and the other is for full time employees that I have encrypted by third party software/server. The IP of the access point is on the protected full time vlan. I want to have another vlan to eb able to dish out ip addresses from a dsl/router where by the isp is local dsl. (hope I didnt confuse)
