Device Tree View
Screen Reference > Network Tree > Device Tree View
"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 or port as well as for each device. You can perform operations such as reviewing information per node.
- Network
- Subnet
- Device (A single device)
- Chassis (such as a physical chassis of the SwitchBlade series and a virtual chassis of the x900 series)
- Slot (such as a linecard of the SwitchBlade series and an expansion module of the x900 series).
- Stack
- Port
"Node" in the SNMP Plug-in's context has nothing to do with the Node for an "AMF Node".

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
Meaning of the status icons varies depending on the node type.
Table 2: Status Icons
| Type
|
Description
|
 Unavailable Icon
|
Indicates that the node is unavailable or the node contains unavailable nodes. Meaning of the icon for each node type is as follows.
- 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.
|
 Trap Icon
|
Indicates that SNMP Plug-in received a trap from the node.
To clear a trap icon, click "Gear" icon on Device Details or Other Node's details page and select "Clear Notification Flag". Trap icons will never go off unless explicitly cleared. It is recommended to clear them once you review the received trap.
|
 Unavailable, Trap Icon
|
Indicates that SNMP Plug-in received a trap from the node and the node is currently unavailable.
|
| Traffic Rate Icon
|
Only shown for a port. It indicates a traffic rate (speed) of the port.
Also refer to Appendix > List of Icons > Status Icons.
10Mbps
100Mbps
1Gbps
10Gbps
A traffic rate icon is only displayed when the port is enabled.
A traffic rate icon is not displayed for a repeater or HUB node.
|
 Blocking Icon
|
Only shown for a port. Indicates that the port is in Blocking state of the Spanning Tree Protocol.
|
 Partition Icon
|
Only shown for a port. Indicates that the port is in automatic partitioning state.

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.
Refer to
Other Nodes for information on details page for node types other than "Device".
Network Attributes
Selecting "Network" in the Tree View shows its attributes in the Node Attribute section.
