Cisco Cisco Aironet 1200 Access Point Notas de publicación

This section lists open and resolved caveats in Cisco IOS Release 12.2(13)JA2.

These caveats are open in Cisco IOS Release 12.2(13)JA2:

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.

CSCec28612—ACL logging is not supported on access point radio interfaces. You must remove the 
log option from the command for the ACL to take effect. However, ACL logging is supported on 
access point BVI interfaces.

CSCec33268—When the access point is configured for optional or mandatory WPA authentication, 
client adapters in Windows XP platforms sometimes experience a delay when initially 
authenticating to the access point immediately after it starts up.

CSCec33519—Administrative users assigned the admin-capability attribute sometimes cannot log 
into the access point using Telnet.

CSCec43008—When you update a WEP key using SNMP, the access point radio does not restart 
automatically, and the access point continues to use the old WEP key.

Workaround: Restart the access point radio after using SNMP to update a WEP key.

CSCec43849—When you configure your access point for MAC address authentication for a large 
number of MAC addresses, client devices sometimes experience long delays when several clients 
roam from one access point to another at the same time.
