This value, delivered as part of an SNMP notification and expressed as a percentage, reports how much of the total buffer memory available to the media-forwarding function on a service PIC is currently being used. A network engineer reads this when investigating a media-forwarding related alert to understand whether buffer memory pressure was the underlying cause, such as when handling an unusually high volume of concurrent mobile data sessions. For example, this field showing a value like 92 (percent) alongside a related alarm would point to buffer memory exhaustion as a likely contributor to whatever problem triggered the notification.
