Cisco Cisco Aironet 350 Access Points 릴리즈 노트

Cisco CKM (CCKM) key management is designed to support voice clients that require minimal roaming 
times. To date, CCKM supports only Spectralink Wireless Phones. Other voice clients have not been 
tested with CCKM and are not supported.

Some non-Cisco Aironet client adapters do not perform 802.1x authentication to the access point unless 
you configure Open authentication with EAP. To allow both Cisco Aironet clients using LEAP and 
non-Cisco Aironet clients using LEAP to associate using the same SSID, you might need to configure 
the SSID for both Network EAP authentication and Open authentication with EAP.

This section lists 

 and 

 in Cisco IOS Release 12.2(13)JA4.

These caveats are open in Cisco IOS Release 12.2(13)JA4:

CSCeb02792—The 802.11a radio in 1200 series access points sometimes erroneously reports 100% 
busy for all frequencies when you run the Carrier Busy test.

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.

CSCeb50727—Unpowered 1100 series access points sometimes cause a loopback when connected 
to switches without loopback detection. When you connect an unpowered 1100 series access point 
to some switches without loopback detection, the access point sometimes causes a loopback. To 
avoid this problem, make sure loopback detection is enabled on the switch to which the access point 
is connected. If your switch does not have loopback detection, disconnect the access point from the 
switch when the access point power is off.

CSCec02800—The access point web-browser interface sometimes displays cached information for 
the Associations page and does not list all associated client devices. 

Workaround: Refresh the Associations page in the web-browser interface to display current client 
associations.

CSCec23329—Access points with PMIP enabled sometimes misinterpret an ARP sent by some 
client devices that check to make sure that their IP addresses are not in use. When the access point 
receives the ARP from the client, the access point interprets the ARP as a DHCP request and disables 
PMIP for the client session.

Workaround: If possible, disable the feature on the client device that automatically sends an ARP to 
the access point to check IP address availability.

CSCec25559—When both 802.11g and 802.11a client devices transmit data simultaneously to the 
802.11g and 802.11a radios in a 1200 series access point, the throughput of the 802.11a radio might 
decrease.
