Caveats
•
CSCsg70979—When a mesh access point (MAP) joins the controller with the default bridge group
name (BGN), the MAP BGN should appear as “DEFAULT.” However, the MAP BGN value is empty
if the MAP does not have a BGN set or if the set value shows up on the controller even though the
MAP joined the controller with the “DEFAULT” BGN string.

•
CSCsg71421—The show qos profile command does not operate properly. The controller does not
allow any further input after this command is entered.

CSCsg71469—When an AP1210 is in the Alert state, it may send deauthentication frames to a rogue
access point.
access point.
•
CSCsg72051—The Wi-Fi Multimedia (WMM) information element broadcast by 1000 series access
points is not recognized by some wireless devices. The devices that do not recognize the WMM
information element can associate to a 1000 series access point but cannot maintain WMM
interoperability with the access point.

information element can associate to a 1000 series access point but cannot maintain WMM
interoperability with the access point.
•
CSCsg75863—If another device on the network takes over the AP-manager IP address, the
controller does not defend its AP-manager IP address. As a result, the ARP cache on the default
gateway router has with the wrong MAC address, and the access points drop off the controller and
bring down the wireless network.

Note
After the default 4-hour ARP refresh interval, the access points rejoin the controller if the
device that took over the AP-manager IP address is removed.

•
CSCsg83671—There is no way to transfer a core-dump file from the controller to a TFTP server.
•
CSCsh04777—The AP1000 does not periodically send neighbor packets on the non-dynamic
frequency selection (DFS) channels (36-48). As a result, the access point is hindered from properly
forming a neighborhood with other access points in the same RF domain.

CSCsh11826—After you search by Ethernet MAC address on the controller, the access point list
does not appear.

CSCsh12616—Pango tags do not obtain a DHCP IP address when a mobility group member is
defined on the controller.

•
CSCsh19882—The IP option in the Protocol drop-down box on the Access Control Lists > Rules >
New page should be changed to “IP in IP” because it permits or denies IP-in-IP packets.

•
CSCsh20492—When mesh access points (MAPs) have more than one SSID, they may reboot after
receiving a configuration request from the controller.

•
CSCsh31384—When Ethernet broadcast and multicast are enabled on the controller and a wired
host sends broadcast packets, the controller does not forward the packets to the access points.

•
CSCsh32320—The Max Retry Count parameter cannot be set to zero.
•
CSCsh35306—Unicast ARPs may drop from export-foreign clients because the IP address is not
known at the foreign controller.

•
CSCsh38353—To enable an SNMP device to determine on which interface a rogue access point is
being detected, radioType must be added to the bsnRogueAP table.

•
CSCsh42496—Ethernet port settings cannot be changed on IOS-running access points.

CSCsh44486—A 1200 series access point sometimes reboots when a client device is associated to
the radio interface that you are configuring.
