We have two WLC'2 4402(sw 18.104.22.168) and one WCS with sw 22.214.171.124. I have a lot of client warnings in the controllers trap logs but none clients alarms on my WCS. Is there any reason why the WCS does not reports client problems ?
Use Administration > Logging to access the Administer Logging Options page. This logging function is only related to WCS logging and not syslog information. The logging for controller syslog information can be done on the Controller > Management > Syslog page.
Email Notification can be done with WCS. WCS includes a built-in email notification function that can notify network operators when critical alarms occur. Refer to the WCS Monitor > All Alarms > Email Notification page to view the current alarm notification settings.
From a command drop-down list, choose Email Notification.
Click GO to access this page.
This page allows you to view the alarm categories with the critical-alarm email notification enabled and disabled, the current From and To email addresses, and the current SMTP server. This page also allows you to enable and disable email notification (check box checked = email notification ON; check box unchecked = email notification OFF) for any or all of the alarm categories, and it allows you to access an alarm category email notification setup page.
For every category except Coverage Holes, the alarm severity must be critical to trigger the email. Email notification is available only for alarms, not for events.
Note: If you do not receive emails from WCS, check whether port 25 is blocked.
Note: A WCS administrator currently has no control over which events generate alarms, when they time out, or the degree of their severity. On the controller, individual types of events can be enabled or disabled (such as management, SNMP, trap controls, etc.).
Configure to use a syslog server on your WLC to see what messages are being sent from it.
Here is how:
Then compare what you receive on the syslog server with what you have in WCS.
The logging settings are for WCS to log information, it does NOT contain any traps from WLC. The traps from WLCs are entered in the WCS database and not the logging.
Also have you customize the level of alarms in WCS? You may change the severity of alarms and that may be a reason what you dont see them.
There is no bug on WCS 126.96.36.199 where no traps are received from the controllers.
Make sure that traps are not blocked between WLC and WCS. That may be your root cause here.
