- Partial SNA Switch—Switch that can be accessed remotely by starting a
management session through an SNA switch. This does not provide discovery,
services explorers or the full SNA feature set.
- Unmanaged Switch— A switch that cannot be accessed through SNA.
• Device Name
• IP Address (A list if more than one is discovered)
• MAC Address (A list if more than one is discovered)
• Number of Notifications–The number of notifications is indicated by a number in
orange on the device icon. The actual notifications are displayed in the right-hand
information panel.
• SNA Support
• Manufacturer
Some devices (particularly SNA-capable devices) have additional information, such as
individual port information. This information can be viewed by clicking on their icon and
displaying a device explorer screen for the device.
Devices in the network are separated into the following categories:
•
Backbone devices – Basic skeleton of the network. By default, all switches, routers
and access points detected on the network are designated automatically as backbone
devices.
After a backbone device is detected, it remains on the topology map until it is manually
removed. If the device is disconnected from the network, it still appears on the
topology map as an offline device.
An SNA-capable device or a managed device remains detected as long as it is
connected to the network by the same IP address it used previously.
•
Offline devices – Backbone devices that were previously added to the topology (either
by the topology detection mechanisms or manually). These devices are now no longer
detected by SNA.
Offline devices have the following characteristics:
-
Distinct visual appearance from online devices on the topology map (see
"Topology
-
Can be moved on the topology, and its placement can be saved. You can also add
tags to the device (see Tags).
