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, undersized 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
Showing Port or Trunk Statistics
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.
The following table lists the options on this page:
