CAUTION: The validity of a USM user depends on the switch fabric ID of the
SNMP agent. If the switch fabric ID used for USM user creation is not identical to
the current switch fabric ID, the USM user is invalid.
Configuring SNMP
Logging
Introduction to SNMP
Logging
SNMP logs the GET and SET operations that NMS performs to SNMP Agent. When
the GET operation is performed, Agent logs the IP address of NMS, node name of
the GET operation and OID of the node. When the SET operation is performed,
Agent logs the IP address of NMS, node name of the SET operation, OID of the
node, the value set and the error code and index returned with the SET operation.
These logs will be transferred to system information and sent to the information
center to be checked and tracked.
SNMP logs GET request, SET request and SET response, but does not log GET
response.
Enabling SNMP Logging
n
■ 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.

By default, SNMP logs are
output to loghost and logfile
only. To output SNMP logs to
other destinations such as
console or monitor terminal,
you need to set the output
destinations with this
command.
