1. Fan and chassis alarms failed to be cleared since January 24.
2. Log in to the management module web user interface (WebUI) using the MM610 floating IP address (10.197.80.134). No alarm is found, but management module active/standby switchover logs are generated when alarms are generated.
3. The IT monitoring platform monitors the E6000 through snmpwalk commands and uses the MM1 static IP address (10.197.80.132) in commands for monitoring. When an MM610 active/standby switchover occurs, the MM1 becomes standby. In this case, if the MM1 static IP address is used in snmpwalk commands to query the fan and power supply unit (PSU) status, incorrect results will be displayed, and the IT monitoring platform reports false alarms, see below:
4. Trigger an MM610 active/standby switchover. Then alarms are cleared.
