"Device Tree View" shows the monitored network components hierarchically.

## Tree View

SNMP Plug-in classifies the network elements to monitor into the following categories. They are collectively referred to as "Node". As the SNMP Plug-in monitor the network per node, you can track the network status for each subnet as well as for each device. You can perform operations such as reviewing information per node.

- Network
- Subnet
- Device (A single device)

> Note

> > "Node" in the SNMP Plug-in's context has nothing to do with the Node for an "AMF Node".

Table 1: Tree View
Item Name | Description
--- | ---
"Gear" icon | Clicking "Gear" icon shows the operation submenu for a node (Network or Subnet) selected on the Tree View. Possible operations are as follows. Network: Add a subnet under the network. Subnet: Add a device under the subnet.
Network Tree | Shows the monitored node hierarchically.
Node | Represents a network element. Each node comprises of one or two icon(s) and a node name. Status Icon: Shows the node status. It is a smaller icon and shown in the leftmost position of a node row. Node Icon: Shows the node type. It is displayed between a status icon and a node name. Name: Shows an administrative name of the node.

### Status Icons

An icon indicates whether the node is available.

Table 2: Status Icons
Type | Description

Network There's a unresponsive device under the node. Subnet There's a unresponsive device under the node. Device The device does not respond. Port The port is disabled (shutdown)
Available Icon | Indicates that the node can be used.

## Node Attributes

"Node Attributes" shows the basic information about a node selected on the Tree View.
When you click the node name in the attribute section, Detailed information page for the selected node type such as Device Details page is displayed.

### Network Attributes

Selecting "Network" in the Tree View shows its attributes in the Node Attribute section.

Table 3: Network Attributes

--- | ---
Subnet Name | "Network"
Monitored Subnets | Shows the number of monitored subnets in the network.
Number of discovered nodes | Shows the number of devices in the network.
Number of managed nodes | Shows the number of detected devices which are monitored. Note The maximum number of devices SNMP Plug-in can monitor is 1000.
Status | Shows the status of the network.

### Subnet Attributes

Selecting a Subnet on the Tree View shows its attribute in the Node Attributes section.

Table 4: Subnet Attributes
Item Name | Contents

Subnet Name | Shows a user-defined name of the subnet.
Network Address | IPv4 address and prefix length (xxx.xxx.xxx.xxx/xx format)
Number of discovered nodes | Shows the number of devices in the subnet.
Number of managed nodes | Shows the number of detected devices which are monitored.
SNMP Parameter Name | Shows a Get Parameter Name used to get information from the device via SNMP.
Status | Shows the status of the subnet.

### Device Attributes

Selecting a Device in the Tree View shows its attributes in the Node Attribute section.
