System Log Configuration - Planet Networking & Communication WGSW-50040 Configuration Manual

informational
debugging
Right now the switch can generate information of following four levels

Restart the switch, mission abnormal are classified critical

Up/down interface, topology change, aggregate port state change of the interface are notifications
warnings

Outputted information from the CLI command is classified informational

Information from the debugging of CLI command is classified debugging
Log information can be automatically sent to corresponding channels with regard to respective severity levels.
Amongst the debugging information can only be sent to the monitor. Those with the Informational level can
only be sent to current monitor terminal, such as the information from the Telnet terminal configuration
command can only be transmitted to the Telnet terminal. Warnings information can be sent to all terminal with
also saved in the SDRAM log buffer zone. And the critical information can be save both in SDRAM and the
NVRAM (if exists) besides sent to all terminals. To check the log save in SDRAM and the NVRAM, we can use
the show logging buffered command. To clear the log save in NVRAM and SDRAM log buffer zone, we can
use the clear logging command.
