Accessible IP List

The VPort uses an IP address-based filtering method to control access to the VPort.

Accessible IP Settings allow you to add or remove “Legal” remote host IP addresses to prevent unauthorized

access. Access to the VPort is controlled by IP address. That is, if a host’s IP address is in the accessible IP table,

then the host will be allowed access to the VPort. Administrators can allow one of the following cases by setting

this parameter:

• Only one host with a specific IP address can access the VPort. Enter “IP address/255.255.255.255” (e.g.,

192.168.1.1/255.255.255.255)

• Hosts on a specific subnet can access the VPort. Enter “IP address/255.255.255.0” (e.g.,

“192.168.1.0/255.255.255.0”)

• Any host can access the VPort. Disable this function.

Refer to the following table for more configuration examples.

SNMP

The VPort 364A supports three SNMP protocols. The available protocols are SNMP V1, SNMP V2c, and SNMP 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 VPort are shown in the following table. Select one of these options to communicate

between the SNMP agent and manager.
