This object is the cell section in a trap message sent from a
monitored device. This object can contain multiple cells.
This object is in the format of '<cell1><cell2>...'. Each cell
consists of 17 octets in the format of
'<TrapOrigin><IfIndex><OverSpeedValue><Threshold><Interval>'.
<TrapOrigin> indicates the source of the trap message and has
size of 1 octet. It only supports the following values.
1 - Global.
2 - Interface.
<IfIndex> is the index of the interface where the rate of ARP packet
exceeds the threshold and has size of 4 octets. It is 0xFFFFFFFF
when <TrapOrigin> is 1(Global).
<OverSpeedValue> indicates the rate that ARP packets are actually
delivered and has size of 4 octets.
<Threshold> indicates the threshold that ARP packets can be delivered
to CPU and has size of 4 octets.
<Interval> indicates the interval that a trap message is sent out
and has size of 4 octets.
