Log settings - Filtering of the system events
Communications problems if the value for system events is set too high
If the value for filtering the system events is set too high, you may not be able to achieve the
maximum performance for the communication. The high number of output error messages
can delay or prevent the processing of the communications connections.
In "Security > Log settings > Configure system events", set the "Level:" parameter to the
value "3 (Error)" to ensure the reliable establishment of the communications connections.
The range of functions of the CP for SNMP can be found in the section SNMP (Page 94).
If the security functions are enabled, you have the following selection and setting options.
●
If the option is enabled, communication via SNMP is released on the device. As default,
SNMPv1 is enabled.
If the option is disabled, queries from SNMP clients are not replied to either via SNMPv1
or via SNMPv3.
●
Enables the use of SNMPv1 for the CP. For information on the configuration of the
required community strings see below (SNMPv1).
●
Enables the use of SNMPv3 for the CP. For information on the configuration of the
required algorithms see below (SNMPv3).
The community strings need to be sent along with queries to the CP via SNMPv1.
●
"Reading community string"

community string can be edited.
