RMON Modes 421
Packet Size 1024-1518 Byte Packets
The number of packets (including bad packets) received that were between 1024 and 1518
octets in length inclusive (excluding framing bits, but including FCS octets).
Broadcast Packets
The number of good packets received that were directed to the broadcast address. Note
that this does not include multicast packets.
Bytes
The number of octets (1 octet = 1 byte) of data (including those in bad packets) received
on the network (excluding framing bits, but including FCS octets). This trigger can be
used as a reasonable estimate of Ethernet utilization.
Setting up an RMON Utilization Trigger
In the Actions dialog, select a “Sampling Interval” that reflects the amount of time (in
seconds) that you would like to average data over. For example, a Sampling Interval of
one second will track the network traffic for one second prior to comparing the upper and
lower thresholds. Set the value for lower threshold to 1 byte less than the upper threshold.
Use the following values for the upper threshold with the following utilizations:
10-Mbit Ethernet:
100-Mbit Ethernet:
10% 125000
20% 250000
30% 375000
40% 500000
50% 625000
60% 750000
70% 875000
80% 1000000
90% 1125000
100% 1250000
