SPFCON

Purpose

The SPFCON utility enables you to monitor Sequenced Packet Exchange^TM (SPX^TM) spoofing statistics.

Spoofing is the process of preserving the transport end point connection by imitating keep alive packets and responding to watchdog request packets without passing this traffic across on-demand WAN links.

Using SPX spoofing can help you maintain lower costs over on-demand WAN links.
