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.

Description

Interface Statistics

Received Octets

The total number of octets received on the
interface, including framing characters.

Received Unicast
Packets

The number of subnetwork-unicast packets
delivered to a higher-layer protocol.

Received Multicast
Packets

The number of packets, delivered by this
sub-layer to a higher (sub-)layer, which were
addressed to a multicast address at this sub-layer.

Received Broadcast
Packets

The number of packets, delivered by this
sub-layer to a higher (sub-)layer, which were
addressed to a broadcas address at this
sub-layer.

Received Discarded
Packets

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.

Received Unknown
Packets

The number of packets received via the interface
which were discarded because of an unknown
or unsupported protocol.
