Working with the Port Log File

ASMi-52 maintains a port alarm buffer, which can store up to 100 alarm messages.

The port log file specifies alarm or event name, severity (major or minor), status

(ON or OFF), and time elapsed since the last ASMi-52 reset.

 To display the log file:

• From the Physical Port Status menu, select Port Log File (Main menu >

Monitoring > Physical Ports Status > Port Log File).

The Log File screen appears (see Figure 6-15).
