What is the difference in coverage and coverage before holes?

Hi all

Anyone know what is the difference in coverage and coverage before holes?

I can find the doc of Cisco is:

«cover holes are displayed as alarms, coverage before holes are displayed as events»

"The gaps or the 'holes' in coverage of radio access point are the main cause of poor audio. Detected on the client before hole events coverage provides continuous monitoring to ensure that the customer is informed about the existence of these cover holes. »

It seems to cover before the hole is detected customer, cover hole is detected AP? However, I'm not sure.

Another question is what trap includes alarm coverage before hole in the dictionary of alarm and event of WCS 7.0? I can only find several cover traps:

LRADIF_COVERAGE_PROFILE_FAILED

LRADIF_COVERAGE_PROFILE_PASSED

However, two of them have no say if for hole cover or the front cover. Don't know what trap will be sent by the WCS to a notification receiver configured to indicate an event coverage before hole, for example:

Minor - X - 13: 27:52 16/09/10 cisco-WCS WCS SNMP <$2>0x07 da 09 10 0d 1 b 2 c b 05 2-0 at 00: 10.1.1.12: coverage before hole reported by 00:1f:3 c: cd:c8:2 detected by 10.1.1.12: coverage before hole reported by ' 00:1f:3 c: cd:c8:2 has ' found on the controller

Your valuable contribution is very much appreciated!

Hello!

A front cover is when a client remains for 5 seconds in a coverage hole. In other words, when a customer is heard for a while to wrong signal and is not roaming, it must mean that this area is a coverage hole. This event is informational

A coverage hole event is when several clients are pasted into the same hole in coverage. Then the AP will increase its power if possible.

WLC waits for several clients before trigger power avoids crazy behaviors of increasine/reduction/increase/decrease.

The settings for cover hole events can be configured on the part of MRR of WLC (number of customers, etc...)

Nothing is configurable for cover before hole because it's just '1 customer only reached the hole in coverage thresholds '.

Hope that clarifies.
