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.
SNA Right-Hand Information Panel View
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:
Devices — When you click on a device, the Header will provide information of the chosen device. The hierarchy of the identification methods is:
— Host name
— IP address
— MAC address
The example below shows that the host name is switche6fa9f with an IPv4 address 192.168.1.127.
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.
Interfaces — When you double-click on the device and choose an interface, the Header will provide information on the chosen interface such as the name of the interface and the strongest form of the device identification it belongs to:
IP address — If the host name is unknown.
MAC address — If both the host name and the IP address are unknown.
Connections — When you click on the link of two or more devices, the Header will show this image:
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.
Manage Device — This option is only available for SNA and partial SNA switches, and only appears when a single device is selected. Selecting this action launches a web management session for the selected switch using the switch management application. You do not need to enter credentials to launch this session.
Explore Device — This option is only available for SNA switches, and only appears when a single device is selected. Selecting this action opens the device explorer for the selected switch.
Explore Connection — This option appears when a single connection is selected. Selecting this action opens the connection explorer for the selected connection.
Explore Client Group — This option appears when a client group is selected. Selecting this action opens the client explorer, filtered by the type of device in the client group.
Delete — This option only appears when all the selected devices are offline devices. Selecting this action deletes all the selected devices from the topology map.
Displays the IP address used by SNA to connect to the device. Additional advertised existing addresses (IPv4 and IPv6) can be seen by pressing the icon next to the label.
The base MAC address of the device.
Editable field of up to 80 characters. Saved on SNA Storage.
Full Support for SNA devices
Partial Support for Managed devices
No SNA support for unmanaged devices
This parameter appears only for switches
Below are the parameters that only appear when View All is clicked. This option is only available if the device is a switch with partial or full SNA capabilities.
A list of the VLANs created on the device. Dashed lines are used to join consecutive VLANs.
1, 6, 13-19, 1054, 2012- 2100, 4094
Active Firmware Version
The version number of the active firmware
The time in days, hours, minutes, and seconds since the device was booted up.
System Local Time
The local time on the device in the format of active language file.
English language file example:
Number of Units
Only appears on stackable devices.
PoE Power on unit # / Available PoE Power
Displayed only on PoE-capable devices.
Displays the available power used out of the maximum power supply.
If the device is a stacked device, a field appears for each PoE-capable unit in the stack with the unit ID. If the device is standalone or a single unit, the label of the field does not mention the unit ID.
This means that a maximum of eight fields may appear here.
The following information is displayed for offline backbone devices under Last Known Information:
Taken from the device description MIB.
This field only appears when the device is a switch with partial or full SNA capabilities.
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.
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.
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.
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:
Last five minutes — 20 samples (one every 15 seconds).
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:
Last five minutes — 20 samples (one every 15 seconds).
