This section demonstrates how to configure SNMP and SNMP Trap/Inform settings.
SNMP
Moxa switches support SNMP V1, V2c, and V3. SNMP V1 and SNMP V2c use a community string match for
authentication, which means that SNMP servers access all objects with read-only or read/write permissions
using the community strings public and private by default. SNMP V3 requires that you select an
authentication level of MD5 or SHA. You can also enable data encryption to enhance data security.
Supported SNMP security modes and levels are shown in the table below. Select the security mode and level
that will be used to communicate between the SNMP agent and manager.

security, it is recommended to install additional security mechanisms such as a firewall to protect critical
infrastructure.
