Примечания к выпуску для Cisco Cisco 2106 Wireless LAN Controller

These caveats are listed in the “Open Caveats” section of the controller release notes for software release 
4.1.171.0 and have been closed in controller software release 4.1.185.0.

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.

CSCsd54171—After you upgrade or modify your controller configuration, the changes might not 
take effect or might not function properly.

Workaround: Follow these steps:

Refresh the configuration from the switch to WCS (deleting any differences).

Clear the configuration on the controller.

Complete the setup wizard, making sure to set the same IP address, community string, and 
country code setting.

Use WCS to restore the configuration to the controller.
