Table 4-15. SNMP NMS Security Options

NMS IP Validation

Possible Settings: Enable, Disable

Default Setting: Disable

Specifies whether security checks are performed on the IP address of SNMP management systems attempting to access the node. Only allows access when the sending manager's IP address is listed on the SNMP NMS Security Options screen.

Enable ± Performs security checks.

Disable ± Does not perform security checks.

Number of Managers

Possible Settings: 1 ± 10

Default Setting: 1

Specifies the number of SNMP management systems that are authorized to send SNMP messages to the FrameSaver unit. An IP address must be configured for each management system allowed to send messages. Configure IP addresses in the NMS n IP Address configuration option.

1 ± 10 ± Specifies the number of authorized SNMP managers.

NMS n IP Address

Possible Settings: 001.000.000.000 ± 223.255.255.255, Clear

Default Setting: Clear (000.000.000.000)

Provides the IP address of an SNMP manager that is authorized to send SNMP messages to the unit. If an SNMP message is received from an unauthorized NMS and its IP address cannot be matched here, access is denied and an authenticationFailure trap is generated. If a match is found, the type of access (read-only or read/write) is determined by the corresponding Access Type.

Display Conditions ± This option appears for each trap manager specified in the Number of Trap Managers configuration option.

001.000.000.000 ± 223.255.255.255 ± Adds to or changes the NMS IP address.

Clear ± Fills the NMS IP address with zeros.

Access Type

Possible Settings: Read, Read/Write

Default Setting: Read

Specifies the type of access allowed for an authorized NMS when IP address validation is performed.

Display Conditions ± This option appears for each trap manager specified in the Number of Trap Managers configuration option.

Read ± Allows read-only access (SNMP Get command) to the MIB objects. This includes all objects specified as either read-only or read/write in the MIB RFCs.

Read/Write ± Allows read and write access (SNMP Get and Set commands) to the MIB objects. However, access for all read-only objects is specified as read-only.
