Advantages of Deploying Air Monitors.

Aruba Employee
Question Why should we deploy Air monitors in our network?
What are the advantages of deploying AM?

 

 

Following is the advantage of deploying Air monitors:

1. AM have more robust containment. AP will not change channel to contain off channel rogue if it has a active client associated with it.  AM will hop to the channel containing rogue alternatively.  If there is a rogue on channel 11 the channel scan would look roughly like 11, 6, 11, 2, 11, 1,,11, 3, 11, 6, 11..\

2. Non-802.11n AP will only scan in the regulatory domain. AM will scan all channels.

3. AP will scan a channel for less than 100ms so that a beacon is not missed in its own channel. AP will scan all channels according to the following:

active                       500ms             
regulatory                250ms
all regulatory           200ms
rare                           100ms

4. Scanning will stop for AP depending upon the factors such as Voice, Video, high throughput or power save aware ( if enabled in ARM profile ). AM doesn't need to stop scanning for any of these factors.

5. AP's primary job is to service the clients. This it can take about 4 minutes to scan all channels. AM can take about 45 seconds to scan all channels.
