Configuring SNMP
The NPort S8000 supports SNMP V1/V2c/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 string public/private (default value). SNMP V3, 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 NPort S8000 are shown in the following table. Select
the security mode and level that will be used to communicate between the SNMP agent and manager.
