Device List

This page lists all devices stored in the SNMP Plug-in's database.

Table 1: Device
Item Name Description
Items per page Lets you select a number of devices displayed on a single page.
"Create" button Lets you add a new device to monitor.

Copy to Clipboard 		Copies the device list (name, status, network address, MAC address, vendor name, model name, polling interval and comment) to clipboard as a tab-delimited text.
It is useful when you want to copy a list to your text editor.
You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.

Export to CSV file 		Exports the device list (name, status, network address, MAC address, vendor name, model name, polling interval and comment) to a CSV file.
You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.

Export to Excel 		Exports the device list (name, status, network address, MAC address, vendor name, model name, polling interval and comment) to an Excel book file (.xlsx for Microsoft Excel 2007 or later).
You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.

Print 		Shows the device list (name, status, network address, MAC address, vendor name, model name, polling interval and comment) on another browser window or tab and opens a print dialog box.
You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.
Search field Lets you filter target subnets by keywords.
The search ignores case. "." and "/" in the search keywords do not match them in the network address ("." and "/" in "192.168.1.0/24").

Destination MAC Address Shows the device MAC address.
Vendor Name Shows the vendor name of the device.
Model Name Shows the model information (SysObjectID).
Monitoring Interval Shows the polling interval for the device.
When it's set to "Auto Detect", the plug-in determines an appropriate interval according to the device level of the device model. In that case "(Auto Detect)" is appended.
Description Shows a comment configured for the device.
"Edit" button Opens Edit Device page for the device.
"Details" button Shows Device Details page for the device.
"Delete" button Opens "Delete Device" dialog box.
Clicking "Yes" in the dialog box deletes the device. Click "No" or "Close (x)" button at the top left of the dialog box allows you to cancel the delete operation and goes back to "Device List" page.

Device

You can add a new device, view a device details or change a device attributes.

Device Details

You can open the "Device Details" page by selecting a device on the Tree View and clicking a device name in the node attributes section on the Device Tree View page.
"Device Details" page shows its attributes and a event list.
Additionally, a line chart shows the device information if SNMP Plug-in can read the device's MIB objects.
Note
When there is a change in the node attributes, such as a change in the model name, the contents of the event list are automatically updated, but the contents of the node attributes are not automatically updated. Please reload your web browser manually.
Note
When the monitored device is registered, if it fails to communicate with the SNMP plug-in, the trend graphs will not be updated. When registering a monitored device, please make sure that it can communicate properly before deleting or adding the device.

Node Attributes

MIB Monitor

Allows you to retrieve information about the device and select individual MIB nodes to display the information.
In addition to the standard MIBs specified in RFCs and the private MIBs of our products, MIBs compiled by the MIB compiler from the MIB files you obtained can be selected from the MIB tree and added to the list.
Note
MIB monitor information is stored in each Web browser. If the MIB Monitor is opened from a different Web browser than the one set up for the MIB Monitor (e.g., access from a different terminal or a different type of Web browser), the contents displayed will be different.

◼ MIB Browser
Lets you select the information (MIB variables) to be displayed on the MIB monitor from the MIB tree.

Table 4: MIB Browser
Item Content
MIB Tree Displays the MIB nodes according to the tree structure.
MIB nodes are displayed in the format of "object name (number)".
A folder icon represents a node with child nodes that further subdivide a particular attribute, and a file icon represents a terminal node (leaf node) that does not have any child nodes.
The object ID (OID) of a node is represented by a sequence of numbers, starting with the first node and followed by the node number separated with periods. For example, the MIB node that represents the system information follows the MIB tree hierarchy "iso(1) -> org(3) -> dod(6) -> internet(1) -> mgmt(2) -> mib-2(1) -> system(1)", so the object ID is represented as "1.3.6.1.2.1.1".
A leaf node may have several pieces of information of the same type, for example, ifSpeed (OID 1.3.6.1.2.1.2.2.1.5), which represents the communication speed of an interface, is stored for each Ethernet interface, such as a port. The number that identifies the same type of information is called an index.
In the MIB Monitor, only leaf nodes can be selected. It is not possible to reference the value of a node that has child nodes.
Node Name Indicates the name of the selected MIB node.
Access Displays the access privileges of the relevant MIB node as either "Read Only" (whose value is automatically set by the system) or "Read/Write" (whose value can be set by the user).
Note
The value cannot be set from the SNMP Plug-in MIB Monitor or MIB Browser.
Status Displays the implementation status of the MIB node in the specification as "Mandatory" or "Optional".
Syntax Displays the data type of the information stored in the MIB node.
Units Displays the units of the values stored in the MIB node.
OID(dot notation) Displays the object ID of the MIB node.
OID(ASN.1 notation) Displays the MIB object name in the form of the node name of each level from the root (top) to the corresponding MIB node, connected by periods.
Module Name Displays the name of the module that defined the MIB node.
Description Displays a description of the MIB node.
Cancel Abort the selection of the MIB object and close the "MIB Browser" dialog box.
OK Add the selected MIB object from the tree into the MIB Monitor.
In the "Select Index" dialog, select the index of the information stored in the corresponding MIB node.
◼ Select Index
The MIB node selected in the "MIB Browser" dialog box may contain more than one of the same kind of information. Select the index of the information to be displayed in the MIB Monitor.

Table 5: Select Index
Item Content
Radio Buttons Select the information to be displayed on the MIB Monitor by checking the MIB variable names and values.
Only one index can be selected at a time. If you want to display information stored in multiple indexes in the MIB Monitor, you need to repeat the selection of MIB nodes and indexes from the "Add" button of the MIB Monitor.
MIB Variable Displays the selected MIB node name and index, connected by periods.
MIB Value Displays the value stored in the MIB variable.
Cancel Aborts the selection of the MIB variable and closes the "Select Index" dialog box.
OK Add the selected MIB variable to the MIB Monitor.

Graph


MIB-based statistics of the device is shown in a trend chart.
You can select variables to show on a chart by clicking their names under the chart's X axis.
Hovering a mouse pointer on a chart shows a value and a date/time at the point.

Event List

You can see a list of event logs on "Event Log List" page.

Add Device

You can open the "Add Device" page by selecting a subnet on the "Tree View" and clicking a "Add Device" from "Gear" icon's submenu on the Device Tree View page.
"Add Device" page lets you add a new device to monitor.
Note
When you add a device manually, there may be a case that its MAC address, IPv4 address and vendor name are not displayed on Device List page. In this case, delete the device and perform Auto Discovery on the target subnet. It may solve the issue and you would be able to see the information.
Note
When using the SNMP plug-in to manage a device with a relatively large number of ports, check the device level in the device level configuration utility, and change the settings if they do not match the following. If you are using a VCS, the number of ports is the total number of ports for the entire stack of connected devices.
  • - The number of ports is 100 or more -> Device level "Low"
  • - The number of ports is 50 to 99 -> Device level "Medium" or "Low"
