Caveats
• CSCso66183—Symbol Vocollect devices might disassociate from Cisco 1240 series access points
and display the following error message:
"3/30/2008 04:42" Error " Mar 30 04:47:25.626 spam_api.c:816 WAPP-3-MAX_AID:
Reached max limit (200) on the association ID for AP 00:1d:a1:90:11:10"
"3/30/2008 04:42" Error " Mar 30 04:47:21.703 spam_api.c:816 WAPP-3-MAX_AID:
Reached max limit (200) on the association ID for AP 00:1d:a1:90:11:10"
Workaround: Manually power-cycle the access points.
• CSCso97776—If you enable MFP when a guest LAN is configured, the controller might show
unwanted logs.
Workaround: None.
• CSCsq01766—When you change an access point’s radio configuration, it sends a deauthentication
request using the wrong BSSID.
Workaround: None.
• CScsq06451—If you configure a guest LAN and map the ingress interface to a guest LAN interface,
you cannot change the mapping to None using the controller GUI.
Workaround: Use this CLI command to change the mapping to None: config guest-lan
ingress-interface 1 none.
• CSCsq06690—The following log might appear unexpectedly on the controller: “Memory
0x3022c8e0 has been freed!”
Workaround: None.
• CSCsq11933—The controller GUI should show additional client counters, such as device type,
rates, current, supported rates, power save, connection-related statistics, and APSD-related
information.
Workaround: None.
• CSCsq14326—A 4400 series controller using a Cisco ACS as a TACACS+ server does not log these
CLI commands into the ACS:
– config hreap group name add
– config hreap group name ap add 00:1c:58:34:40:cc
– config hreap group name ap add 00:1a:a1:3f:07:08
– config hreap group name delete
Workaround: None.
• CSCsq19324—If you enter a long value for the access control list (ACL) name on the Access
Control Lists page of the controller GUI and click Apply, the value appears in HTML text below the
ACL Name field.
Workaround: None.
• CSCsq19430—The GUI of a 2106 controller shows a guest LAN interface, even though it is not
supported.
Workaround: None.
• CSCsq19472—Cisco Compatible Extensions RM measurements are inaccurate if beacon, channel
load, frame, and noise histograms are triggered together.
Workaround: Trigger the RM measurements one at a time.
• CSCsq21956—An error occurs when you create a guest user and then try to edit the guest user’s
parameters such as lifetime, role, and so on through the controller GUI.
