Introduction

The SNMP protocol is used for monitoring, error detection and error notification and is standardized.
The SNMP configuration of the UTM generally allows read-only access.
The UTM supports the following version of the SNMP protocol:

SNMP version 1
SNMP version 2c
SNMP version 3

Version 3 of the SNMP protocol allows encrypted communication. SHA1 and AES are used for encryption.

If this data is requested, SNMP version 3 must be used for data protection reasons mandatory!
