An RRM−related information exchange takes place once the AP is provisioned. A typical exchange between
the AP and the WLC (ap−manager interface) is approximately 1400 bytes. In the event of an RRM−related
configuration change, there is a four−packet exchange between the AP and the ap−manager interface of the
WLC. This exchange averages 375 bytes.

A 20−minute sample capture that includes the discovery, join, configuration, and on−going processes resulted
in these traffic statistics on a 100Mbps segment:
