OL-11186-01
Important Notes
DFS Not Supported on Certain 1130 Series Access Points
1130 series access points with FCC Certification Number (LDK102054) do not support dynamic
frequency selection (DFS) on channels 52 to 64 and 100 to 140 in the US and Canada. The FCC
Certification Number (also called FCC ID number) is shown on the product label on the bottom of the
unit. Only access points with LDK102054E on the product label can support DFS in the US and Canada.

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

interfering with them. Radios configured for use in Europe and Singapore also use DFS. Other regulatory
domains do not use DFS. Refer to the
for detailed information.
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 350, 1130, 1200, 1230, 1240 series access point, or a 1300 series outdoor access
point/ridge 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.

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.

Save Interface Level Configuration Before Upgrading to Releases 12.3(8)JEA or
Later
Later
If the access points have SSIDs configured at the interface level (rather than at the global level), before
upgrading to Cisco IOS Release 12.3(7)JA and above, upgrade to Cisco IOS Release 12.3(4)JA, save the
configurations and then upgrade to Release 12.3(8)JEA. This procedure must be followed to make sure
that the SSID configurations are converted from the interface level to global level.
