Cisco Cisco 4402 Wireless LAN Controller

CSCsb01980—When the operator enters incorrect data for the management interface in the 
controller web configuration wizard, error messages are shown only at the end of the wizard, and 
the user must return to the Management Interface page for correction. The data entered on the 
Management Interface page, such as the port number, are not validated immediately but at the end 
of the wizard. As a result, any error messages are shown only at the end.

Workaround: Use the CLI configuration wizard.

CSCsb01983—The controller web configuration wizard is not reachable after making repeated 
invalid entries for the management interface port. If an operator connects to the wizard on address 
192.168.1.1 and enters an invalid port number on the Management Interface page, the operator is 
redirected at the end of the wizard to the Management Interface page to correct the port. If the 
operator enters an incorrect port and submits, the wizard becomes inaccessible.

Workaround: Reboot the controller through the CLI to access the wizard again.

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.
