Planning for Network Growth
Segments Excluded from Analysis
Segments Excluded from Analysis
Analysis of network traffic is possible for all segments with HP devices
attached to them that have Extended RMON sampling capability, but may be
performed for only a subset of the segments. This strategy best utilizes system
resources for gathering information about the segments most likely to have
traffic flow problems.
Segments that do not have Devices with Sampling
Capability
When no HP devices with Extended RMON sampling capability are attached
to a segment, only SNMP data is incorporated into the analysis. These
segments are listed as Overutilized Segments in the “Segments Excluded from
Analysis” section of the Add or Upgrade Equipment Report. A recommenda-
tion may be made to upgrade the segment to a faster speed if there is only one
end node on the segment.
Segments not Selected for Analysis
If a segment is not considered a likely source of traffic problems, it may be
excluded from analysis. If the segment traffic increases significantly, it will be
included in future analyses of the network.
