QUESTIONS TO HELP ISOLATE THE PROBLEM
When a problem occurs, attempt to answer the following questions:
1
What is the history of the problem?
Have we changed something recently?
Have we seen other symptoms before this?
2
How wide-spread is the symptom?
Is the problem on only a single SM? (If so, focus on that SM.)
Is the problem on multiple SMs? If so:
o
is the problem on one AP in the cluster? (If so, focus on that AP)
o
is the problem on multiple, but not all, APs in the cluster? (If so, focus on those
APs)
o
is the problem on all APs in the cluster? (If so, focus on the CMM and the GPS
signal.)
3
Based on data in the System Log
Is intermittent connectivity indicated? (If so, verify your configuration, power level, CINR,
cables and connections, and the speed duplex of both ends of the link).
Does the problem correlate to loss-of-sync events?
4
Are connections made via
shielded
cables?
5
Does the GPS antenna have an
unobstructed
view of the entire horizon?
