Performing Advanced Configuration
Severity Levels
There are three severity levels for system alarms:
–
Critical
–
Major
–
Informational
Critical alarms will often result in severe disruption in network activity or an automatic reboot of the AP
Major alarms are usually activated due to a breach in the security of the system. Clients cannot be authenticated or an
attempt at unauthorized access into the AP has been detected.
Informational alarms are there to provide the network administrator with some general information about the activities
the AP is performing.
Alarm Host Table
To add an entry and enable the AP to send SNMP trap messages to a Trap Host, click Add, and then specify the IP
Address and Password for the Trap Host.
NOTE
Up to 10 entries are possible in the Alarm Host table.
•
IP Address: Enter the Trap Host IP Address.
•
Password: Enter the password in the Password field and the Confirm field.
•
Comment: Enter an optional comment, such as the alarm (trap) host station name.
To edit or delete an entry, click Edit. Edit the information, or select Enable, Disable, or Delete from the Status
drop-down menu.
Syslog
The Syslog messaging system enables the AP to transmit event messages to a central server for monitoring and
troubleshooting. The AP can send messages to multiple Syslog servers. The access point logs "Session Start (Log-in)"
and "Session Stop (Log-out)" events for each wireless client as an alternative to RADIUS accounting.
See RFC 3164 at
http://www.rfc-editor.org
Setting Syslog Event Notifications
Syslog Events are logged according to the level of detail specified by the administrator. Logging only urgent system
messages will create a far smaller, more easily read log then a log of every event the system encounters. Determine
which events to log by selecting a priority defined by the following scale:
Event
LOG_EMERG
LOG_ALERT
LOG_CRIT
LOG_ERR
LOG_WARNING
LOG_NOTICE
LOG_INFO
LOG_DEBUG
Configuring Syslog Event Notifications
You can configure the following Syslog settings from the HTTP interface:
•
Enable Syslog: Place a check mark in the box provided to enable system logging.
•
Syslog Port Number: This field is read-only and displays the port number (514) assigned for system logging.
•
Syslog Lowest Priority Logged: The AP will send event messages to the Syslog server that correspond to the
selected priority and above. For example, if set to 6, the AP will transmit event messages labeled priority 0 to 6 to
the Syslog server(s). This parameter supports a range between 1 and 7; 6 is the default.
for more information on the Syslog standard.
