Command History
Usage Guidelines
If you enable coverage hole-detection, the switch 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.
If both the number and percentage of failed packets exceed the values that you entered in the ap dot11 {24ghz | 5ghz} rrm coverage packet-count and ap dot11 {24ghz | 5ghz} rrm coverage fail-percentage commands for a 5-second period, the client is considered to be in a pre-alarm condition. The switch 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 | 5ghz} rrm coverage level-global and ap dot11 {24ghz | 5ghz} rrm coverage exceptional-global commands over a 90-second period. The switch determines whether the coverage hole can be corrected and, if appropriate, mitigate the coverage hole by increasing the transmit power level for that specific access point.
