Showing Port Statistics

You can display standard statistics on network traffic from the Interfaces
Group and Ethernet-like MIBs, as well as a detailed breakdown of traffic
based on the RMON MIB. Interfaces and Ethernet-like statistics display
errors on the traffic passing through each port. This information can be
used to identify potential problems with the switch (such as a faulty port or
unusually heavy loading). RMON statistics provide access to a broad range
of statistics, including a total count of different frame types and sizes
passing through each port. All values displayed have been accumulated
since the last system reboot, and are shown as counts per second. Statistics
are refreshed every 60 seconds by default.
Note: RMON groups 2, 3 and 9 can only be accessed using SNMP
management software such as HP OpenView.

Description
The total number of octets received on the interface,
including framing characters.
The number of subnetwork-unicast packets delivered
to a higher-layer protocol.
a higher (sub-)layer, which were addressed to a
multicast address at this sub-layer.
The number of packets, delivered by this sub-layer to
a higher (sub-)layer, which were addressed to a
broadcast address at this sub-layer.
The number of inbound packets which were chosen
to be discarded even though no errors had been
detected to prevent their being deliverable to a
higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer
space.
