Cisco Cisco Wireless Control System Version 4.0

This section describes important information about Cisco WCS.

If you see access points with the same name while applying controller templates or adding them to the 
map, perform a refresh config. The duplicates in the database will be eliminated.

You must enter an email address when configuring high availability. WCS tests the email server 
configuration and if the test fails (because the mail server cannot connect), WCS does not allow the high 
availability configuration.

High availability is supported on Linux, on Windows 2003, and on VMware environments. Specific 
operating system support is listed in the 

The new client session report replaces the existing Client Association and Client Detail Report. If you 
perform an upgrade, Client Association no longer appears in the Reports menu. The data pertaining to 
these reports migrates successfully, and saved report entries for Client Association and Client Detail 
reports are migrated. However, the new ClientSessionInfo table is not populated with data from the 
previous reporting period; the table is populated with client-related data that occurred after upgrade. The 
new client detail report contains the details of association time, disassociation time, and session timeout 
along with details of VLAN, session length, client location, Megabit information used, SNR, RSSI, and 
throughput.

Cisco WCS is supported only on English or Japanese versions of the Windows 2003 operating system. 
Display problems sometimes occur when you install and run Cisco WCS on operating systems translated 
to other languages or with locale settings other than English or Japanese.

If a domain name is not set in the email settings, notifications may end up in the junk email. When the 
primary device is down, no email notifications are received, but the log message indicates that an email 
was successfully sent.
