Guidelines for Using 1130AG Series Lightweight Access Points Chapter 4 Troubleshooting Lightweight Access Points Guidelines for Using 1130AG Series Lightweight Access Points Keep these guidelines in mind when you use a 1130AG series lightweight access point: • The access points can only communicate with Cisco 2006 series or 4400 series controllers. Note Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series controllers are not supported because they lack the memory required to support access points running Cisco IOS software. • The access points do not support Wireless Domain Services (WDS) and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it. • The access points support eight BSSIDs per radio and a total of eight wireless LANs per access point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1 through 8 are pushed to the access point. • The access points do not support Layer 2 LWAPP. They must get an IP address and discover the controller using DHCP, DNS, or IP subnet broadcast. • The access point console port is enabled for monitoring and debug purposes (all configuration commands are disabled when connected to a controller). Using DHCP Option 43 You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling the access point to find and join a controller. For additional informataion, refer to the "Configuring DHCP Option 43 for Lightweight Access Points" section on page G-1. Checking the Lightweight Access Point LEDs If your access point is not working properly, check the Status LED on the top panel or the Ethernet and Radio LEDs in the cable bay area. You can use the LED indications to quickly assess the unit's status. Figure 4-1 shows the access point LEDs. Cisco Aironet 1130AG Series Access Point Hardware Installation Guide 4-2 OL-8369-05

Troubleshooting Lightweight Access Points

Guidelines for Using 1130AG Series Lightweight Access Points

Keep these guidelines in mind when you use a 1130AG series lightweight access point:

•

The access points can only communicate with Cisco 2006 series or 4400 series controllers.

Note

Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series controllers are not

supported because they lack the memory required to support access points running Cisco

IOS software.

•

The access points do not support Wireless Domain Services (WDS) and cannot communicate with

WDS devices. However, the controller provides functionality equivalent to WDS when the access

point associates to it.

•

The access points support eight BSSIDs per radio and a total of eight wireless LANs per access

point. When a lightweight access point associates to a controller, only wireless LANs with IDs 1

through 8 are pushed to the access point.

•

The access points do not support Layer 2 LWAPP. They must get an IP address and discover the

controller using DHCP, DNS, or IP subnet broadcast.

•

The access point console port is enabled for monitoring and debug purposes (all configuration

commands are disabled when connected to a controller).

Using DHCP Option 43

You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling

the access point to find and join a controller. For additional informataion, refer to the

“Configuring

DHCP Option 43 for Lightweight Access Points” section on page G-1

Checking the Lightweight Access Point LEDs

If your access point is not working properly, check the Status LED on the top panel or the Ethernet and

Radio LEDs in the cable bay area. You can use the LED indications to quickly assess the unit’s status.

Figure 4-1

shows the access point LEDs.
