The Smart Network Application (SNA) is a system that displays an overview of the network topology including detailed monitoring information for devices and traffic. SNA enables viewing and modifying of configurations globally on all supported devices in the network.
The area to the right of the topology map of the SNA displays an information panel which displays attributes of the selected elements and enables performing actions on them.
This article explains the features and functions of the Right-Hand Information Panel of the SNA.
Note: Devices from the Sx250 Series can provide SNA information when they are connected to the network, but SNA cannot be launched from these devices.
The right-hand information panel contains the following blocks:
The header displays the icon for the selected element or elements, and if only one element is selected, the header displays its identifying information, as shown below:
— Host name
— IP address
— MAC address
Note: If the host name, IP address, and MAC address of a device are known, the host name and the IP address are shown. If the host name or IP address is not known, the MAC address replaces the missing attribute similar to the sample image below.
When selecting multiple elements, the Header shows the number of elements selected, and if all selected elements are of the same type, the header also shows their type. In the example below, the type is not displayed because the types were not consistent.
Selecting a client group is a shortcut to selecting all members of the group. The header shows the number and type of device in the group.
When selecting a client group together with other devices, the client groups counts as the number of devices that are contained in it. For example, when selecting a backbone device and a client group containing five clients the header shows six devices selected).
If notifications exist for the device, the number of notifications is displayed:
The following actions can be performed on the selected devices or connections. To perform these actions, click on the cogwheel icon in the right-hand information panel.
The Basic Information block displays attributes of the selected single element. The block is not displayed when more than one entity is selected.
Some of the information is shown at all times, and some is shown only if the View All button is clicked.
If no information is received on a certain parameter, that parameter is not displayed in the Basic Information section.

The notification block displays the latest notifications or System Logs (SYSLOGs) recorded on the selected device.
The notifications section only appears when selecting a single SNA device. When you click on the Show Notifications link, the Notifications page will display.
This section of the information panel displays available services for the current selection of elements. Only services that are relevant for all selected elements are displayed. This section is not displayed if elements, which do not support services, are a part of the selection, or when devices and interfaces are selected together.
For more information about Services, click here.
Tags are used to identify elements in the topology by attributes. The Tag block of the right-hand information displays all the tags assigned to the element, either automatically or by the user. You can also manage the tags of the selected elements from this part of the panel.
For more information about Tags, click here.
When viewing an SNA-capable device, or the interfaces on an SNA-capable device, you can select to view historical statistics information on that interface or device.
The Statistics view is accessed from the right-hand information panel.
To view historical statistics on an interface or device, choose a specific parameter to view from a list of available parameters, according to the parameters supported by the embedded counters history feature. You can then view the status of this parameter on the selected interface for the previous year.
The following graphs can be viewed:
This graph is a port-level graph that shows the port utilization percentage of the port over time. It is available for all ports of devices with full SNA support. You can select a number of ports to run a side-by-side comparison.
The data is shown as a percentage (0-100) with number and frequency of samples depending on the displayed time scale:
This graph is a port-level graph that shows the PoE utilization of the port over time. It is available for all PoE ports of devices with full SNA support.
You can select a number of ports to run a side-by-side comparison.
The data is shown as a number of watts (0 - 30/60 depending on whether the port has PoE+ capability) with number and frequency of samples depending on the displayed time scale:
This graph is a device-level graph that shows the PoE utilization of the device over time. The graph is available for all PoE devices with full SNA support. The graph is represented per unit, and you can select a number of units (from a single or multiple stacks) to view simultaneously.
The data is shown as a number of watts (0 being the PoE capacity of the selected unit with the highest capacity) with numbers and frequency of samples depending on the displayed time scale:
This graph is an interface-level graph that shows the total traffic on an interface in bytes over time. The graph is available for all interfaces of devices with full SNA support and has separate lines for Tx and for Rx traffic. You can select a number of ports and types of traffic to run a side-by-side comparison.
The data is shown as a number of octets (0 - highest sample in selected interfaces/time period) with number and frequency of samples depending on the displayed time scale:
