Usage Guidelines
If you enable coverage hole detection, the controller automatically determines, based on data that is received
from the access points, whether any access points have clients that are potentially located in areas with poor
coverage.
from the access points, whether any access points have clients that are potentially located in areas with poor
coverage.
If both the number and percentage of failed packets exceed the values that you entered in the ap dot11 24ghz
rrm coverage data packet-count count and ap dot11 24ghz rrm coverage data fail-percentage percentage
commands for a 5-second period, the client is considered to be in a pre-alarm condition. The controller uses
this information to distinguish between real and false coverage holes and excludes clients with poor roaming
logic. A coverage hole is detected if both the number and percentage of failed clients meet or exceed the
values entered in the ap dot11 24ghz rrm coverage exception and ap dot11 24ghz rrm coverage level
commands over a 90-second period. The controller determines whether the coverage hole can be corrected
