1-4. Outline of Communication

A controller (PC) communicates with a display according to the communication data format. Communication is started by issuing a command from the controller. Communication is terminated when the display sends return data (an answer message) to the controller after it receives the issued command.

It is inhibited that a controller sends multiple commands at a time.

Therefore, a controller cannot send other commands until return data is sent back from a display after it sends one command. The display sends return data after command processing is completed.

Section 2

SNMP

2-1. SNMP

This unit installs SNMP (Simple Network Management Protocol). SNMP is a standard protocol for network management that was standardized in IETF (Internet Engineer Task Force).

By using SNMP, the management information of equipment connected to a network can be gotten via a network. The information of multiple equipment gotten using SNMP can also be unitarily managed by using SNMP management software.

The equipment corresponding to SNMP has a “management information database” called MIB (Management Information Base) in the inside of equipment. In SNMP, the bidirectional communication of data contained in MIB is realized between a “management system” and “management object system” that exist in a network.

In MIB, there is the standard MIB prescribed by RFC. Especially, MIB-II is its representative MIB. MIB-II was established to manage a network. MIB-II is installed in much network equipment such as a PC, router, and switch as a standard feature. This unit installs this MIB-II.

Monitoring and monitored sides exist when equipment is monitored via a network using SNMP. The monitoring side is called an “SNMP manager”. It is mainly constituted by the software of PC. For the monitored side, a module called an “SNMP agent” is installed. SNMP-compatible equipment transmits MIB information to an SNMP manager via this SNMP agent. This unit installs this SNMP agent. This unit can realize the communication with a general-purpose SNMP manager using this SNMP agent. Basically, an SNMP agent replies only when an inquiry is sent from an SNMP manager.

The SNMP manager periodically inquires the equipment, which it manages, about MIB information. This way to get information is called “polling”. In polling, equipment replies using a response command when an SNMP manger sends a request command to equipment. By polling, therefore, equipment can be monitored without applying a high load to the equipment.

On the other hand, notification can also be done from the equipment side to an SNMP manager. This notification is called a “trap”. Using this trap, when a serious trouble occurred in equipment, it can be notified to the SNMP manager in a short time.

This unit is compatible with the two polling and trap protocols described above. Equipment can be efficiently monitored using these protocols.

GXD-L52H1

2-2. Specifications of SNMP Installation

The specifications of the SNMP agent installed in this unit are shown in below.

.SNMP version:	SNMPv1
.MIB definition:	SMIv2
.Support PDU:	GetRequesat
	SetRequest
	GetNextRequest
	Trap

.Standard MIB to be installed: MIB-II

2-3. Installation

The setting below is required to use the SNMP function of this unit. (Set according to your network environment and SNMP management environment.)

.Community and its Community property

.Authentication trap

.Host restriction

The Web server function of this unit is used for setting. Refer to the Operation Manual of this unit for the operation of the Web server.

The contents of each item and the setting of SNMP are fully described in this specification.

2-4. Operation of SNMP Setting Window

This section describes the procedure and contents for

setting of SNMP.

Open the Web page of this unit and click the [SNMP] button in the Advanced setting item on the Setup page (where an administrator’s password is necessary). The SNMP setting window is displayed.

GXD-L52H1

2-4-1. Community

A Community name is used as the password for SNMP access. The request received from an SNMP manager is accepted when the Community name contained in the request coincides with the Community name set. The request is rejected when the former does not coincide with the latter.

A maximum of three Communities can be set.

There are “Rights” and “Trap destinations” items in the property of Community. The property can be set for each set Community.

n

When multiple Communities are set, all set Communities are validated.

1. Rights

The rights that can be set are as follows:

Read Only:	An SNMP manager can reference MIB information using this Community name.
Read Write:	This Community must be set when a write request is sent from an SNMP manager.
Other:	Do not set this option because it is used for the function extension in future.

2. Trap destinations

When Trap destinations are set, during trap occurrence, a trap is notified to the equipment set as trap destinations using the Community name set.

Up to four Trap destinations can be set to one Community. Trap destinations are not set in default.

n

This product can be set on only the Web screen because it does not install the automatic setting function of Trap destinations.

3. Setting procedure of Community

Community can be added, edited, and removed.

The addition, editing, and removal procedures of Community are described below.

Addition of Community

1.Click the [Add] button.

The “Community name”, “Rights”, and “Trap destinations” text boxes, and [Set|to|List] and [Cancel] buttons are validated.

2.Type the Community name you want to add.

3.Set the Rights of Community and the Trap destinations you want to add.

When you want to save the setting, click the [Set|to|List] button and then click the [Apply] button at the bottom of the window.

m

.Click the [Cancel] button when you want to discard the setting during setting.

.When you want to save setting, be sure to click the [Set|to|List] button and then click the [Apply] button.

Editing of Community

1.Select the Community, you want to edit, from a drop-down list.

2.Click the [Edit] button.

The “Community name”, “Rights”, and “Trap destinations” text boxes, and [Set|To|List] and

[Cancel] buttons are validated.

Edit the Community name when you want to edit a Community name.

3.Set the Rights of Community and the Trap destinations you want to edit.

m

.Click the [Cancel] button when you want to discard the setting during setting.

.When you want to save the setting, click the [Set|to|List] button and then click the [Apply] button at the bottom of the window.

Removal of Community

1.Select the Community, you want to remove, from a drop-down list.

2.Click the [Remove] button and then click the [Apply] button at the bottom of the window. n

Be sure to click the [Remove] button and then click the [Apply] button.

2-4-2. Authentication Trap

An authentication trap is the trap for making it detect by an SNMP manager that an illegal access was gained to this unit using an SNMP protocol.

.The authentication trap is validated when this check box is selected. A trap is transmitted when an illegal access is gained.

.The authentication trap is invalidated when this check box is not selected. A trap is not transmitted even if an illegal access is gained.

n

Be sure to click the [Apply] button when you edited setting.

2-4-3. IP Restriction of Host

It is possible to put restrictions on the IP address of an SNMP manager, as one of the security countermeasures, which communicates using an SNMP protocol.

.IP address restriction is invalidated when you select “Accept packets from any host”.

.Only the SNMP access from an SNMP manager that has the set IP address is accepted when you select “Accept packets from those hosts”. The SNMP access from an IP address that has not been set is rejected.

m

.Up to four IP restrictions can be set.

.Be sure to click the [Apply] button when you edited setting.

GXD-L52H1

2-5. MIB to Be Installed

This unit installs MIB-II.

MIB-II is the most representative standard MIB. It is installed in various network products.

The statistical information on the amount of network traffic or the number of transmitted and received packets is defined, and the change or transition can be monitored by polling the information periodically. Additionally, the management items to be installed can be defined using a TCP/IP device so as to get the information effective for the monitoring of the network communication state.

Refer to RFC1213 for the detailed definition of MIB-II.

2-6. Information to Be Notified on Trap

In software version 2.0 or later, the software have a function that transmits error information to this unit. The error trap and authentication trap are installed.
