Client Roaming - Cisco 2100 Series Configuration Manual

Adding Mesh Access Points to the Mesh Network
Using the CLI to Configure Antenna Gain
Using the controller CLI, follow these steps to configure the antenna gain.
To configure the antenna gain for the 802.11a backhaul radio, enter this command:
Step 1
config 802.11a antenna extAntGain antenna_gain Cisco_AP
where antenna_gain is in 0.5-dBm units (for example, 2.5 dBm = 5).
To save your changes, enter this command:
Step 2
save config
Workgroup Bridge Groups on Mesh Access Points
A workgroup bridge (WGB) connects a wired network over a single wireless segment by learning the
MAC addresses of its wired clients on the Ethernet interface and reporting them to the mesh access point
using Internet Access Point Protocol (IAPP) messaging. The mesh access point treats the WGB as a
wireless client.
When configured as a WGB, the 1130, 1240, and 1310 autonomous access points as well as the series
3200 mobile access router (MAR) can associate with mesh access points. The mesh access points can be
configured as RAPs or MAPs. WGB association is supported on both the 2.4-GHz (802.11b) and 5-GHz
(802.11a) radio on the 1522, and the 2.4-GHz (802.11b) and 4.9-GHz (public safety radio) on the 1524.
Note Refer to the "Cisco Workgroup Bridges" section in Chapter 7 of this manual for configuration details.

Client Roaming

High-speed roaming of Cisco Compatible Extension (CX), version 4 (v4) clients is supported at speeds
up to 70 mph in outdoor mesh deployments of 1522 and 1524 mesh access points. An application
example might be maintaining communication with a terminal in an emergency vehicle as it moves
within a mesh public network.
Cisco Wireless LAN Controller Configuration Guide
8-24
The 1130, 1240, 1310 autonomous access point must be running Cisco IOS release 12.4(3g)JA or
later (on 32-MB access points) or Cisco IOS release 12.3(8)JEB or later (on 16-MB access points).
Cisco IOS releases prior to 12.4(3g)JA and 12.3(8)JEB are not supported.
If your mesh access point has two radios, you can only configure workgroup bridge mode
Note
on one of the radios. Cisco recommends that you disable the second radio. Workgroup bridge
mode is not supported on access points with three radios such as 1524.
Client mode WGB (BSS) is supported; however, infrastructure WGB is not supported.
Mesh access points can support up to 200 clients including wireless clients, WGBs, and wired
clients behind the associated WGBs.
WGBs operating with Cisco IOS release 12.4(3g)JA cannot associate with mesh access points if the
WLAN is configured with WPA1 (TKIP) +WPA2 (AES), and the corresponding WGB interface is
configured with only one of these encryptions (either WPA1 or WPA2).
