Wireless Access Points

Hi All,

Quick question, what is the Maximum number SSID's can one have per Cisco 1100 and 1200 series AP and what are the limitations,

[Rob Huffman]

Hi Tau,

Autonomous 1100 and 1200 Series;

You can configure up to 16 SSIDs on your access point and assign different configuration settings to each SSID.These are the settings you can assign to each SSID:

•VLAN

•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!

PS: I hope you were referring to Autonomous AP's :)

Thanks Rob,

What about LWAPP ?? Is this Posible as well.

Hi Tau,

You are most welcome my friend :)

You can have multiple SSID's using the WLC and LWAPP AP's. In this model, SSID's are tied to WLAN's. Have a look;

http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00805e7a24.shtml

APs that are converted to LWAPP mode support eight basic service set identifiers (BSSIDs) per radio and a total of eight WLANs per AP.

When a converted AP associates to a WLC, only the WLANs with IDs 1 through 8 are pushed to the AP.

From this good Q & A doc;

Access Points Converted to LWAPP Support 8 BSSIDs per Radio

Access points converted to LWAPP mode support 8 BSSIDs per radio and a total of 8 wireless LANs per access point. (Cisco 1000 series access points support 16 BSSIDs per radio and 16 wireless LANs per access point.) When a converted access point associates to a controller, only wireless LANs with IDs 1 through 8 are pushed to the access point.

From this AP 1230 doc;

http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_release_note09186a00804fc3b6.html#wp153975

Q. What features present in Cisco Aironet 1000 Series Access Points will not be available in the LAP versions of Cisco Aironet 1100, Aironet 1130 AG, Aironet 1200, Aironet 1230 AG, Aironet 1240 AG, and Aironet 1300 Series Access Points?

A. While the vast majority of LWAPP features are supported by these access points, there are some features available on Cisco Aironet 1000 Series Access Points that are not available on LAP access points. None of these features are considered to be significant obstacles to a full WLAN deployment; they are listed here so that customers can be fully aware of any device limitations.

Support for 8 instead of 16 basic service set identifiers (BSSIDs)

Background: LAP devices will support a maximum of 8 BSSIDs per access point. Cisco Aironet 1000 ***Discontinued*** Series Access Points support up to 16 BSSIDs per access point.

The need for more than 16 BSSIDs is minimized because of the LWAPP architecture's "Identity-Based Networking" feature, whereby the authentication, authorization, and accounting (AAA) server can map, on a per-user basis, between any wireless BSSID to any of 256 wired-side VLANs.

From this good LWAPP doc;

Hi,

In Lightweight Configuration each SSID is associated with a WLAN.

"In controller software release 4.2 or later, all Cisco lightweight access points support 16 BSSIDs per radio and a total of 16 wireless LANs per access point. In previous releases, they supported only 8 BSSIDs per radio and a total of 8 wireless LANs per access point. When a converted access point associates to a controller, only wireless LANs with IDs 1 through 16 are pushed to the access point."

This is what is mentioned in the following link -

http://www.cisco.com/en/US/docs/wireless/controller/5.0/configuration/guide/c5lwap.html#wp1129862

Thus you can have 16 SSIDs on the AP.

This is my understanding based on the documents. Never tried this practically.
