Logs occupy storage space of the device, thus affecting the performance of the device. Therefore,
you are recommended to disable SNMP logging.

The priority of SNMP log is informational, meaning it is a common prompt of the device. To check
SNMP logs, enable the information center to output system information with the severity of
informational.

The size of SNMP logs cannot exceed that allowed by the information center and the sum of the
node, and value field of each log information cannot exceed 1K bytes; otherwise, the exceeded
