Cisco Wireless Controller Basic Setup

I purchased a Cisco 2906 wireless controller and three lightweight waps for a client and am trying to bring it online

The initial config is fine and I can get to the gui in a browser.
I have created a wlan and I *believe* I need to point that to a dynamic interface. However, I cannot figure out the correct address for that dynamic interface. The documentation leads me to believe it must be on a different subnet, but I'm not sure.

If I'm not mistaken, once I clear this hurdle, I should just be able to plug the wap into the correct port and then repeat for the two other waps. Correct?

Thanks
Steve

If you controller is configured correctly, once you connect your WAP to your LAN, with power, it will find the controller the the controller will download the boot code to the WAP. So yes you are correct.

wantabe, you mean the 2nd part of the question, right?

What I still don't know how to do it configure those dynamic ports, but they sure seem to need to be on a different subnet.


Commented:
I think I'm a little confused. I've logged into 6 of my controllers here looking to see what your refering to & don't see any dynamic ports on the controller interface. Are you refering to the AP manager or the virtual interface?

I'm referring to dynamic interfaces, this is from p.3-8 of the config guide (800 pages!)

Dynamic interfaces, also known as VLAN interfaces, are created by users and designed to be analogous
to VLANs for wireless LAN clients. A controller can support up to 512 dynamic interfaces (VLANs).
Each dynamic interface is individually configured and allows separate communication streams to exist
on any or all of a controllers distribution system ports. Each dynamic interface controls VLAN and other
communications between controllers and all other network devices, and each acts as a DHCP relay for
wireless clients associated to WLANs mapped to the interface. You can assign dynamic interfaces to
distribution system ports, WLANs, the Layer 2 management interface, and the Layer 3 AP-manager
interface, and you can map the dynamic interface to a backup port.
You can configure zero, one, or multiple dynamic interfaces on a distribution system port. However, all
dynamic interfaces must be on a different VLAN or IP subnet from all other interfaces configured on the
port. If the port is untagged, all dynamic interfaces must be on a different IP subnet from any other
interface configured on the port.

Ok, I think I know whatyour refering to. I don't think you need a dynamic interface. I have three static interfaces on all my wireless controllers. I have the following:

1 - AP-Manager    static interface

2 - virtual Interface    static interface

3 - Managment Interface     static interface


When you say you connect via a web browser, you're probably typing in the managment interface IP in te browser correct? When you create an additional interface on the controller, you can create a dynamic or static interface. The dynamic interface would be good for different security issues, For example, if you have a guest SSID for users to comeonto your WLAN, you don't know if there computer is fully patch or the virus defs are up to date, so you could force them off to a different VLAN via the dynamic interface, so their traffic would not hurt the other traffic on your LAN/WLAN. I hope this helps.

You are correct with the exception of the part where you say I can create a static interface, I can only create dynamic. There is a diagram i the manual that indicates I may have to use a dynamic as well.

Thx

The key was changing some settings on the switch. Cisco was very helpful. This is an extremely complicated piece of hardware. Thanks all.

I agree. I always recomend buying SmartNet for at least one year when buying Cisco stuff.

smartnet?

Commented:
Yes, if you spoke with Cisco tech support, you had to give them the serial number off of something. If that device was not covered under smartnet, they WOULD not have talked to you. SmartNet is basically warranty & tech support.
