Cisco Cisco Aironet 1200 Access Point 릴리즈 노트

When you ping or run a link test from an access point to a client device installed in a PC running 
Microsoft Windows 2000, the ping or link test sometimes fails when the client has both wired and 
wireless connections to the LAN. Microsoft does not recommend this configuration. For more 
information, refer to Microsoft Knowledge Base article 157025 at this URL:

Repeater access points and workgroup bridges cannot associate to an SSID configured for Layer 3 
mobility. Layer 3 mobility is not supported on repeaters and workgroup bridges.

You must use a Wireless LAN Services Module (WLSM) as your WDS device in order to properly 
configure Layer 3 mobility. If you enable Layer 3 mobility for an SSID and your WDS device does not 
support Layer 3 mobility, client devices cannot associate using that SSID.

Cisco IOS Release 12.3(2)JA changes the default behavior of access points requesting an IP address 
from a DHCP server:

When you connect a 350, 1130AG, or 1200 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. 

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.
