From here, you can Enable or Disable the Log settings for the EWS switch.
The System Log is designed to monitor the operation of the EWS switch by recording the event messages it generates during normal operation. These events may provide vital information about system activity that can assist in the identification and solutions of system problems.
The EWS switch supports log output to two repositories: Flash and RAM. The information stored in the system’s RAM log will be lost after the switch is rebooted or powered off, whereas the information stored in the system’s Flash will be kept even after the switch is rebooted or powered off. The flash repository has a fixed capacity; at a certain level, the EWS switch will start deleting the oldest entries to make room for the newest.
Severity Level
RFC 5424 defines eight severity levels:
The internal log of the EWS switch has a fixed capacity; at a certain level, the EWS switch will start deleting the oldest entries to make room for the newest. If you want a permanent record of all logging activities, you can set up your syslog server to receive log contents from the EWS switch. Use this page to direct all logging to the syslog server. Click the Add button, define your syslog server, and select the severity level of events you wish to log.
This page displays the most recent records in the EWS switch's internal log. Log entries are listed in reverse chronological order (with the latest logs at the top of the list). Click a column header to sort the contents by that category.
Export Click Export button to export the current buffered log to a .txt file.
Clear Click Clear button to clear the buffered log in the system's memory.
