94 Chapter 6 Configuring RMON using Device Manager
Field Description
Interval The interval in seconds over which the data is sampled
for each bucket in the part of the media-specific table
associated with this entry. You can set this interval to
any number of seconds between 1 and 3600 (1 hour).
Because the counters in a bucket can overflow at their
maximum value with no indication, note the possibility
of overflow in any of the associated counters. It is
important to consider the minimum time in which any
counter can overflow on a particular media type; set the
historyControlInterval object to a value less than this
interval. This is typically most important for the octets
counter in any media-specific table. For example, on
an Ethernet network, the etherHistoryOctets counter
can overflow in about one hour at the Ethernet
maximum utilization.
Owner The network management system that created this
entry.
