Working with reports and displays
The report uses the Color Legend to indicate the tunnel state. The description of the colors codes in the
legend is given below:
Green - Altitude AP has established an active tunnel.
Blue - Altitude AP has established a backup tunnel.
Red - Altitude AP is not connected.
In the report, each Altitude AP is represented by a box.
The label, Foreign or Local, indicates whether the Altitude AP is local or foreign on the Summit WM
Controller.
The color in the upper pane of the box represents the state of the tunnel that is established to the
current Summit WM Controller.
NOTE
The current Summit WM Controller is the one on which the Altitude AP Availability report is viewed.
The color in the lower pane of the box represents the state of the tunnel that is established with the
other Summit WM Controller.
For the ease of understanding, take the example of the following scenario:
WM1 and WM2 are paired in session availability
An Altitude AP has established an active tunnel to WM1.
The same Altitude AP has established a backup tunnel to WM2.
If you open the Altitude AP Availability report on WM2, the report will appear as follows:
In the above screen shot, the Altitude AP, which is circled, has established backup tunnel to the foreign
(secondary) Summit WM Controller, and active tunnel to the local (Primary) Summit WM Controller.
