Hi Landy, As explained (probably deep in the details), some configuration and event are triggered using SNMP.
For example, for a switch to know of a client in OpenFlow, we have to look at packet-in from the client. This can take a while, esp. for clients that does not perform DHCP upon association. By using something like SNMP, we can send a SNMP trap/inform when the client associate with the AP or base-station. This allows for a much faster reaction to a client association, thus improving handover. Hope the explanation is clear.
