Deactivating/activating SNMP
Under certain conditions, it is useful to deactivate SNMP. Examples:
● The security guidelines in your network do not allow the use of SNMP.
● You use your own SNMP solution, e.g. with your own communications instructions.
If you deactivate SNMP for a device, various options for diagnostics of the network topology (e.g. using the PRONETA tool
or the Web server of the CPU) are no longer available to you.
To deactivate/activate SNMP for the integrated interfaces of the CPU, follow these steps:
1. In STEP 7, create a data block that contains the structure of data record B071
–
The following table shows the structure of the data record B071

2. Transfer the data record B071
Use the diagnostics address of an integrated interface of the CPU here.
