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
•
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.
