Problem 1: Changes made to Unconnected Nodes or Removed by Synchronize submaps are not be
retained when the map containing them is saved.
Problem 2: Background images cannot be tiled in Topology Manager. If you have converted maps from
an earlier release of Console that contained a tiled Device status is not being updated when
connectivity is lost. This can happen when an AP4000 is using SNMPv3 credentials and has
a sysUpTime greater than approximately 200 days. All devices in the poll group containing
the AP4000 device will be affected. maps from an earlier release of Console that contain
device icons that you changed in the prior release, they will appear in Topology Manager
with the standard icon for the device type.
