RMON Configuration
2-3
IV. History group
After a history group is configured, the Ethernet switch collects network statistics
information periodically and stores the statistics information temporarily for later use. A
history group can provide the history data of the statistics on network segment traffic,
error packets, broadcast packets, and bandwidth utilization.
With the history data management function, you can configure network devices to
collect history data, sample and store data of a specific port periodically.
V. Statistics group
Statistics group contains the statistics of each monitored port on a network device. An
entry in a statistics group is an accumulated value counting from the time when the
statistics group is created.
The statistics include the number of the following items: collisions, packets with cyclic
redundancy check (CRC) errors, undersize (or oversize) packets, broadcast packets,
multicast packets, and received bytes and packets.
With the RMON statistics management function, you can monitor the use of a port and
make statistics on the errors occurred when the ports are being used.
Note:
It is required to configure the history group and the statistics group in port view because
they are port-oriented RMON groups.
