Viewing Event Messages

A wireless access point is a complex piece of network equipment that includes both hardware and software components. Multiple software features operate simultaneously, interoperating with each other and processing large amounts of network traffic. It is often difficult to determine exactly what is happening when an access point appears not to be operating normally, or what happened when a problem occurred.

You may monitor the operations of the access point by viewing the messages in its event log. The events and the vital information about system activity that they provide can help you identify and solve system problems.

The access point has two types of event messages:

System messages

Kernel messages

System messages, which cover a variety of events, such as authentications of 802.1x wireless users and hardware or software problems, are divided by severity into the following categories:

0 - Emergency

1 - Alert

2 - Critical

3 - Error

4 - Warning

5 - Notice

6 - Informational

7 - Debug

System event messages are stored in the event log on the access point and can be viewed from web browser management sessions of the device, as explained in “Viewing System Event Messages” on page 115. They can also be sent to a syslog server on your network for more permanent storage, as described in “Configuring the Syslog Client” on page 118.

System event messages can be stored in either volatile or non-volatile memory. Messages stored in volatile memory, the default setting, are discarded whenever the unit is reset or powered off.

When system event messages are stored in non-volatile memory, they are retained even when the unit is powered off or reset. This can be useful if you are troubleshooting a problem with the unit or network. However,
