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.
