Issue:
Incorrect MANAGEMENT AGENT LOST alarms seen on Blue Coat devices

 
Resolution:
An issue has been identified on Blue Coat devices where MANAGEMENT AGENT LOST alarms are seen in Spectrum.

Running a packet capture during the times that these alarms are raised can be seen that getnext requests are sent from the device but Spectrum does not acknowledge these.

This issue has been verified as being a device side problem not with Spectrum.

The time ticks values sent by the device are not valid and Spectrum therefore does not acknowledge them.
