Caveats
•
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.

•
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.
client devices that check to make sure that their IP addresses are not in use. When the access point

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.

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.

•
CSCec55763, CSCec55820—When both the 802.11g and 802.11a radios in a 1200 series access
point simultaneously operate under extremely high data loads for an extended period, the 802.11a
radio sometimes hangs or the access point reboots.

radio sometimes hangs or the access point reboots.
•
CSCec59848—The access point uses only multiples of 8 for the Max Data Retries setting on the
802.11g radio. If you set the Max Data Retries setting to a value that is not a multiple of 8, the access
point rounds down to the closest multiple of 8. For example, if you set Max Data Retries to 20, the
access point rounds the setting down to 16.
