Configuring RMON
History Samples
Use the Administration > RMON (Configure Interface - Add - History) page to collect
statistics on a physical interface to monitor network utilization, packet types, and
errors. A historical record of activity can be used to track down intermittent
problems. The record can be used to establish normal baseline activity, which may
reveal problems associated with high traffic levels, broadcast storms, or other
unusual events. It can also be used to predict network growth and plan for
expansion before your network becomes too overloaded.
Command Usage
◆
Each index number equates to a port on the switch.
◆ If history collection is already enabled on an interface, the entry must be
deleted before any changes can be made.
◆
The information collected for each sample includes:
input octets, packets, broadcast packets, multicast packets, undersize packets,
oversize packets, fragments, jabbers, CRC alignment errors, collisions, drop
events, and network utilization.
For a description of the statistics displayed on the Show Details page, refer to
“Showing Port or Trunk Statistics” on page 102 .
◆
The switch reserves two index entries for each port. If a default index entry is re-
assigned to another port using the Add page, this index will not appear in the
Show nor Show Details page for the port to which is normally assigned. For
example, if control entry 15 is assigned to port 5, this index entry will be
removed from the Show and Show Details page for port 8.
Parameters
These parameters are displayed:
◆ Port – The port number on the switch.
◆ Index - Index to this entry. (Range: 1-65535)
