The Moxa smart switch supports 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, which is the most
secure protocol, requires that you select an authentication level of MD5 or SHA.
You can also enable data encryption to enhance data security. SNMP security
modes and levels that are supported are shown in the following table. Select the
security mode and level that will be used to communicate between the SNMP
agent and manager.

all configuration parameters. Accounts with user authority only have read access to
