This section describes important information about the access point.
CCKM and Fast Roaming on Cisco 7921/7925 IP Phones
When a 7921 or 7925 wireless associates to an access point in a WDS with CCKM, it cannot fast roam
because call admission control is not enabled. To work around this issue you must enable admission
control by issuing the admit-traffic command in the access point SSID configuration as shown in the
following example:

Layer 3 Not supported with NAC for MBSSID
Layer 3 is not supported with NAC for MBSSID in this release.
DFS Enabled by Default on 5-GHz Radios in North America
In this release, Dynamic Frequency Selection (DFS) is automatically enabled on 5-GHz radios
configured for use in North America. The 5-GHz radios use DFS to detect radar signals and avoid
interfering with them. Radios configured for use in Europe and Singapore also use DFS. Other regulatory
domains do not use DFS. Refer to the

Change to Default IP Address Behavior
Cisco IOS Releases 12.3(2)JA and later change the default behavior of access points requesting an IP
address from a DHCP server:
address from a DHCP server:
•
When you connect a 1200 or 1230 series access point with a default configuration to your LAN, the
access point requests an IP address from your DHCP server and, if it does not receive an address,
continues to send requests indefinitely.
access point requests an IP address from your DHCP server and, if it does not receive an address,
continues to send requests indefinitely.
•
When you connect an 1100 series access point with a default configuration to your LAN, the 1100
series access point makes several attempts to get an IP address from the DHCP server. If it does not
receive an address, it assigns itself the IP address 10.0.0.1 for five minutes. During this five-minute
window, you can browse to the default IP address and configure a static address. If after five minutes
the access point is not reconfigured, it discards the 10.0.0.1 address and reverts to requesting an
address from the DHCP server. If it does not receive an address, it sends requests indefinitely. If you
miss the five-minute window for browsing to the access point at 10.0.0.1, you can power-cycle the
access point to repeat the process.
