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
