Troubleshooting
The troubleshooting function is applicable to clients associated with Comware-based APs (fat APs or fit
APs).
The troubleshooting function allows you to troubleshoot client access failure or unstable link status. In
addition, you can perform NQA operations to test links between AC and website, AAA server, DNS
server, or portal server to determine whether the problem is caused by external network failures.
You can view the spectrum analysis data, including channel usage, channel quality, RSSI, and
interference devices, in the troubleshooting page. You can locate the problem in the WLAN, for
example, find out the interference devices, based on the spectrum analysis data.
Prerequisites
Before using the troubleshooting function, complete the following tasks:
• Verify that the alarm management module and the syslog management module are installed and
deployed.
The troubleshooting function uses the syslogs sent by the AC to the IMC Platform for
troubleshooting client access status in real time. Before using the troubleshooting function, you
must install and deploy the syslog management and alarm management modules. Otherwise,
the troubleshooting function cannot take effect.
• Disable the filtering rule Filter Trap to configure the IMC Platform not to filter the syslogs sent by
the AC or the fat AP.
• Enable the troubleshooting function on the AC or fat AP.
WSM collects syslogs sent by the AC or fat AP only after the troubleshooting function is
enabled.
