A fixed switch can record alarms but not logs after a loop detection-enabled interface detects
a loop. The configurations are as follows:
In V100R005 and V100R006, you can run the snmp-agent trap enable feature-name
ldttrap command to enable the alarm function for loop detection. If snmp-agent trap
enable has been configured globally, the alarm function has been enabled.
Loop detection and loopback detection have been available since V200R001. You can
run the snmp-agent trap enable feature-name ldttrap command to enable the alarm
function for loop detection and run the snmp-agent trap enable feature-name lbdt
command to enable the alarm function for loopback detection.
You can run the display trapbuffer command to view alarms.
