Cisco Cisco Aironet 1200 Access Point Release Notes

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 Releases 12.3(2)JA and later change 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.

 and 

 in Cisco IOS Release 12.3(4)JA.

These caveats are open in Cisco IOS Release 12.3(4)JA:

CSCeb52431—When logging into a TACACS+ server, 1100 series access points sometimes send 
hundreds of additional authentication requests to the server after a successful authentication.

CSCef11167—The access point sometimes returns an inaccurate value when you poll 
cDot11ActiveWirelessClients through SNMP.

CSCef95410—When an access point is configured to interact with a WDS device, the WLCCP 
packets that it receives from the WDS device sometimes cause the radio interface output drop 
counter to increment when it should not.

CSCeg19614—When a 1200 series access point is configured as a workgroup bridge, it does not 
display the client devices attached to its Ethernet port.

CSCeh38024—Access point WPAv2 migration mode does not support Cisco Aironet CB20A client 
radios running firmware version 2.0.0.184 configured for optional WPAv2.

Workaround: Configure the access point for WPAv2 with TKIP + WEP40/128, or configure the 
access point for mandatory WPAv2.

CSCsa44859—350 series access points sometimes display tracebacks when you configure a VLAN 
and do not assign an SSID to it.
