The validity of a USM user depends on the engine ID of the SNMP agent. If the engine ID
generated when the USM user is created is not identical to the current engine ID, the USM user
is invalid.
Configuring SNMP Logging
Introduction to SNMP Logging
SNMP logs the Get and Set operations that the NMS performs on the SNMP agent. When the
GET operation is performed, the agent logs the IP address of the NMS, node name of the GET
operation and OID of the node. When the SET operation is performed, the agent logs the IP
address of the NMS, node name of the SET operation, OID of the node, the value configured
and the error code and error index of the SET response. These logs will be sent to the
information center, and the level of them is informational, that is, they are taken as the system
prompt information. With parameters for the information center configured, the output rules for
SNMP logs are decided (that is, whether the logs are permitted to display and the output
destinations).
SNMP logs Get requests, Set requests and Set responses, but does not log Get responses.
Enabling SNMP Logging
To do… Use the command… Remarks
Enter system view system-view —
Enable SNMP logging
snmp-agent log { all |
get-operation | set-operation }
Required
Disabled by default.

trap { level severity | state
state } * ] *
Optional
By default, SNMP logs are
output to loghost and logfile
only. To output SNMP logs to
other destinations such as the
console or a monitor terminal,
you need to set the output
destinations with this command.
