Caveats
•
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.

•
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.

CSCec60868—Changing the TKIP MIC failure holdoff time to a non-default value triggers the
holdoff timeout in these situations:
holdoff timeout in these situations:
–
Immediately after you set the timeout to a non-default value, the holdoff timeout is in effect and
clients cannot associate for the specified holdoff period. However, if you set the holdoff timeout
to the default value (60 seconds), the timeout is not triggered immediately after you set it.

to the default value (60 seconds), the timeout is not triggered immediately after you set it.
–
When the access point reboots, the holdoff timeout is triggered and clients cannot associate until
the timeout expires. However, the timeout is not triggered after a reboot if the timeout is set to
the default value (60 seconds).

•
CSCin60014—These invalid configurations cause radio errors:
–
WPA optional with the TKIP cipher
–
WPA mandatory with TKIP+WEP40
–
WPA mandatory with TKIP+WEP128
Configuring WPA is a two step process and the access point can be in an invalid configuration when
client devices associate resulting in radio errors. This invalid condition occurs when the access point
is changed from a WPA mandatory configuration to a WPA optional configuration or vice versa.
client devices associate resulting in radio errors. This invalid condition occurs when the access point
is changed from a WPA mandatory configuration to a WPA optional configuration or vice versa.
Workaround: To prevent client devices from associating to the access point during the invalid WPA
configuration period, you must deactivate the radio prior to changing the configuration and
reactivate the radio when the configuration changes are complete.

CSCec72841—The ARP cache feature is not supported on repeater access points.

CSCec73044—When WPA is configured on the access point, associated client devices occasionally
report MIC failures on packets from the access point.

CSCec73037—Packet replay detection messages occasionally appear when a WPA client
reauthenticates to the access point. The client sometimes loses its connection to the access point, but
the client attempts to reconnect.
