2.2 Rmon Configuration - H3C S5100-SI Operation Manual

With the history data management function, you can configure network devices to collect history
data, sample and store data of a specific port periodically.
5. Statistics group
Statistics group contains the statistics of each monitored port on a switch. 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.
