Non-intrusive,in-band
Virtual Circuit (VC)Traffic
Group Measurements: % bandwidth
utilization, kbps, delays, VC status
(24hour)
Detail: Frames, octets, kbps, delay
measurements, VC status
VCStatus Up, down, BECN set, FECN set, DE set,
bandwidth utilization threshold exceeded,
delay threshold exceeded
VCTraffic Detail Measurement Intervals
Current/previous second; cur/prev 15
min; cur/prev 2 hour; cur 24 hour;
previous 7 complete days, 12 2-hour
intervals for current day
VCDelay Measurements
