Cisco Cisco Aironet 1200 Access Point Release Notes

CSCdy12876—1200 series access points sometimes lock up under extremely large bursts of 
Ethernet traffic. Reboot the access point if it locks up.

CSCdy13227—Repeater statistics page is invalid. When you associate a repeater access point to a 
root access point, a link to the repeater appears on the root access point’s Summary Status screen. 
However, when you click the link the page does not appear.

CSCdx19068—Unlimited LEAP logins configuration on ACS server can lock out roamed clients. 
When the ACS server’s session policy is configured for other than unlimited simultaneous LEAP 
logins and a LEAP-enabled client device roams away from the access point long enough for a STOP 
record to appear in the Radius Accounting log, the client cannot reauthenticate until it is purged 
from the list of logged-in users on the ACS server. Workaround: Set the server’s IETF (028) idle 
timeout attribute to a low value so the server ends the roamed client’s session and the client can start 
a new session when it returns.

CSCdx19118—The access point reboots when more than 23 workgroup bridges are associated to it 
and you change one of these settings:

SSID on the Express Setup or AP/Root Radio Hardware pages

Classify Workgroup Bridges as Network Infrastructure on the AP/Root Radio Advanced page

Requested Status on the AP/Root Radio Advanced page from Up to Down and back to Up

CSCdy20169—When a 1200 series access point boots, it sometimes displays this warning:

(Warning) Routine "pktRouterRcvRtn" is unable to Take the forwardTbl Guard semaphore

You can ignore this message.

CSCdy23465—Access points sometimes fail to connect to the DNS server and report this error: 

Repeatedly failed to connect to DNS Server. Temporarily DISABLING DNS lookups. To 

re-enable, explicitly Disable then re-Enable DNS on the Name Server Setup page.

To re-enable DNS lookups, select Disabled for the Domain Name System setting on the Name 
Server Setup page and click Apply. Then select Enabled and click Apply.

CSCdy24215—When the Cisco Catalyst 4000 Series Switch provides inline power to a 1200 series 
access point, the power at startup is sometimes higher than the access point’s steady state level, 
causing the access point to reboot. Workaround: Use a power source other than the Cisco Catalyst 
4000 Series switch to power the access point.

CSCdy25035—You must reboot the access point when you enable or change accounting parameters 
before the new settings take effect.

CSCdy27377—The Search for Least Congested Channel feature does not work for the 5-GHz radio. 

CSCdy27831—When you set the default Unicast Address Filter to disallowed, you must reboot the 
access point before the setting takes effect.

CSCdx32469—When you set up a standby access point with Open authentication with Require EAP 
enabled and with LEAP enabled, the radio on the monitored access point shuts down approximately 
one minute after you enable hot standby. When the radio on the monitored access point shuts down, 
the standby access point takes over as the primary access point. Workaround: Enable static WEP or 
no WEP on the standby access point.

CSCdx41471—Enabling MIC on 1200 series access points can decrease throughput by up to 30% 
for the access point’s highest data rates.

CSCdw53237—When you change the access point’s role in radio network from repeater to root, the 
link from the access point to the previous root device remains active. Workaround: Reboot the access 
point after changing its role from repeater to root.
