This counter tracks the number of MP link packets that were interleaved with higher-priority traffic queued in the Real-Time Transport Protocol Queue or Low Latency Queue. Admins monitoring VoIP or other latency-sensitive traffic over a multilink bundle use this counter to confirm that PPP multilink interleaving, fragmenting large packets to let voice packets through faster, is actually taking effect. A steadily increasing count on a bundle carrying voice traffic confirms that large data packets are being fragmented to avoid delaying voice frames.
