The Filter bar at the top of the screen provides a way to navigate through the network hierarchy (see File>Configure to see how to group network devices). At the top level, a list of Zones is shown, once you have selected a zone, the view will drill down to only show information from the selected zone, and a list of Groups will appear. Select a group and the view will drill down to only show the information from the selected group and a list of Agents will appear. Finally if you select an agent, its Interfaces will be shown. Click on the links at any level in the path and you will move back up the tree to that level. If a single agent has been selected a Details button will appear. Click on the button to see detailed information about the agents (see Search>Agent/Interface).
Each column in the table indicates the status of either network devices, or of traffic thresholds. The columns are:
- Status, indicates whether the device is up or down as determined by a ping test.
- Frames, interface frame/s threshold status
- Utilization, interface percentage utilization threshold status
- Broadcasts, interface broadcast frames/s threshold status
- Multicasts, interface multicast frames/s threshold status
- Errors, interface error frames/s threshold status
- Discards, interface discarded frames/s threshold status
Each row of status indicators summarizes the worst status of all the interfaces in a part of the network. The top, Site, row summarizes status for the whole site. The next, Summary, row summarizes status all the other rows in the table. In addition to indicating threshold status (see File>Configure for information on configuring thresholds), color shade indicates whether flow information is available. Flow information allows traffic sources to be identified.
| Flows=No | Flows=Yes | Description |
|---|---|---|
 |
|
Unknown There is no status value, either because no counter data is available, or because there are no thresholds set. |
|
|
Good Counter value does not exceed threshold value. |
|
|
Warn Counter has exceeded threshold value in at least once, but not enough times to cause an alert. |
|
|
Critical Counter has exceeded threshold value often enough to generate an alert. |
Click on status boxes to identify worst interfaces (see Traffic>Interfaces). Click on the region label to the right of the status boxes to drill-down into specific regions of the network.
Additional status information is displayed when viewing status at
the interface level. Individual interfaces may not have a status value if
they are not active, either because they are disconnected,
,
or administratively disabled, 
.
When viewing a device's interfaces, addition options appear in the Filter. The Show option button may have one or more of the following options (depending on the capabilities of the device):
- Interfaces, show details all the labels for each interfaces.
- Hosts, show the hosts connected to each interface. Click on a host name to get more information about the host.
- Neighbors, show the neighboring devices connected to each interface. Click on the device name to get more information about the device.
- Interface Stack, view the interfaces organized by containment hierarchy, indented interfaces are sub interfaces of the less indented parents above them in the list.
- Component, view the interfaces organized by device components, indented interfaces are attached to the less indented component above them in the list.
- All, show all interfaces.
- Active Only, show only the interfaces that are active.
SNMP is used to obtain detailed device and interface information. If SNMP access is fails this is indicated with the message:
No SNMP information available.Possible reasons for this message include:
- The device does not support SNMP.
- The incorrect community string has been configured (see File>Configure for information on configuring SNMP).
- The device may have an access control setting that limits SNMP access.
