Cisco Cisco Aironet 1200 Access Point Notas de publicación

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.

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. 

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:

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.

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
