SNMP
VPort supports three SNMP protocols. The available protocols are SNMP V1, SNMP V2c, and
SNMP V3. The SNMP V1 and SNMP V2c protocols 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 string public/private (default value). The SNMP V3 protocol,
which requires you to select an authentication level of MD5 or SHA, is the most secure protocol.
You can also enable data encryption to enhance data security. SNMP security modes and security
levels supported by the VPort are shown in the following table. Select one of these options to
communicate between the SNMP agent and manager.
