Cisco Cisco 2000 Series Wireless LAN Controller

CSCsb07168—The AP1000 802.11a radio experiences a very low receive packet count when the 
receive RSSI is –75 dBm.

Workaround: None at this time.

CSCsb20269—On the WiSM, when the service VLAN is configured as one of the VLANs on a data 
port, it does not operate correctly.

Workaround: Do not configure the service VLAN as one of the VLANs on a data port.

CSCsb34149—Disabling or deleting a wireless LAN on which a large number of clients exists may 
not result in all clients being deleted. This generally occurs when several thousand clients are using 
the wireless LAN.

Workaround: Make sure that wireless LANs with a large number of clients associated are not deleted 
or disabled.

CSCsb38486—The Cisco Aironet 1500 Series Lightweight Outdoor Access Point Bridge CLI does 
not accept 10-character bridge group names.

Workaround: Use 9-character bridge group names.

CSCsb52557—Cisco access points do not connect to the 4400 series controller if the time is not set 
first.

Workaround: Set the time on the controller before allowing the access points to connect to the 
controller.

CSCsb55597—The access point’s output power may change after you modify a mandatory data rate.

Workaround: None at this time.

CSCsb55937—VLAN-tagged large ICMP packets that need to be fragmented are not sent by Cisco 
Aironet 1000 series access points in direct-connection mode. Ping replies never come back when the 
access point sends requests to a gateway from a wireless client using large 1500-byte packets and 
with RADIUS override configured with any 1p tag. 

Workaround: None at this time. 

CSCsb71060—Internal LAG errors occur when the management interface is changed from tagged 
to untagged.

Workaround: Leave the WiSM management interface as tagged or untagged.

CSCsb77595—When logging out from Telnet/SSH sessions, the session always prompts the user to 
save changes, even when no changes have been made. 

Workaround: Answer Yes or No when prompted.

CSCsb85113—When users download the code image to WiSM using the CLI, associated access 
points are sometimes disconnected.

Workaround: Download new code images to the WiSM at times when there are no clients to be 
affected. 

CSCsb88588—Incorrect power levels are reported for access points when the controller is set to 
country code SG.

Workaround: None for this release.

CSCsc01221—When downstream test data is sent from the wired endpoint to four wireless clients 
at different priority levels (voice, video, background, and best effort), the Cisco Aironet 1000 series 
access points crash. 

Workaround: None for this release.
