The following connection widths are available (from narrowest to widest):
•
Level 1—Less than 1GB
•
Level 2—1GB to less than 10GB
•
Level 3—More than 10 GB
Links whose capacity cannot be calculated or links between a backbone device and its clients
are shown as level 1 links.
The connection between SNA-capable devices is detected from both sides. If there is a
difference between the calculated capacities of the connection between the two sides, the
width is drawn according to the lower of the two values.
You can enter a connection explorer for specific links by clicking on the link. The following
information is displayed:
•
Port(s) names on the two sides of the link (if known)
•
LAG IDs if relevant.
•
Basic information about the connected devices: device type/device name/IP
•
Link bandwidth for each link comprising the connection
Clouds
Clouds are sections of the network that SNA cannot map in detail. They are indicated by the
following icon:
SNA may determine that more than one device is connected to the network through a specific
port, but is unable to map the relationship between those devices. This occurs because there
are no SNA-capable devices among them. SNA draws a cloud on the topology map and
displays the devices detected in this cloud as connected clients.
Most SNA operations are not applicable to clouds.
