SNR S2940-8G-v2 Switch Configuration Guide
Monitor and Debug
• Restart the switch, mission abnormal, hot plug on the CHASSIS switch chips are classified
critical
• Up/down interface, topology change, aggregate port state change of the interface are notifi-
cations 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.
