The display parameters, when the argument is '<slot/port>', are as follows :
Packets Received
Octets Received
- The total number of octets of data (including
those in bad packets) received on the network (excluding framing
bits but including Frame Check Sequence (FCS) octets). This
object can be used as a reasonable estimate of ethernet utilization.
If greater precision is desired, the etherStatsPkts and etherStat-
sOctets objects should be sampled before and after a common
interval. ----- The result of this equation is the value Utilization
which is the percent utilization of the ethernet segment on a scale
of 0 to 100 percent.
Packets Received < 64 Octets
- The total number of packets
(including bad packets) received that were < 64 octets in length
(excluding framing bits but including FCS octets).
Packets Received 64 Octets
- The total number of packets
(including bad packets) received that were 64 octets in length
(excluding framing bits but including FCS octets).
Packets Received 65-127 Octets
- The total number of packets
(including bad packets) received that were between 65 and 127
octets in length inclusive (excluding framing bits but including
FCS octets).
Packets Received 128-255 Octets
- The total number of packets
(including bad packets) received that were between 128 and 255
octets in length inclusive (excluding framing bits but including
FCS octets).
Packets Received 256-511 Octets
- The total number of packets
(including bad packets) received that were between 256 and 511
octets in length inclusive (excluding framing bits but including
FCS octets).
Packets Received 512-1023 Octets
- The total number of pack-
ets (including bad packets) received that were between 512 and
1023 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets Received 1024-1518 Octets
- The total number of pack-
ets (including bad packets) received that were between 1024 and

1518 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets Received 1519-1522 Octets
- The total number of pack-
ets (including bad packets) received that were between 1519 and
1522 octets in length inclusive (excluding framing bits but
including FCS octets).
Packets Received > 1522 Octets
- The total number of packets
received that were longer than 1522 octets (excluding framing
bits, but including FCS octets) and were otherwise well formed.
Packets Received Successfully
Total
- The total number of packets received that were without
errors.
Unicast Packets Received
- The number of subnetwork-unicast
packets delivered to a higher-layer protocol.
Multicast Packets Received
- The total number of good packets
received that were directed to a multicast address. Note that this
number does not include packets directed to the broadcast
address.
Broadcast Packets Received
- The total number of good packets
received that were directed to the broadcast address. Note that
this does not include multicast packets.
Packets Received with MAC Errors
Total
- The total number of inbound packets that contained errors
preventing them from being deliverable to a higher-layer proto-
col.
Jabbers Received
- The total number of packets received that
were longer than 1518 octets (excluding framing bits, but includ-
ing FCS octets), and had either a bad Frame Check Sequence
(FCS) with an integral number of octets (FCS Error) or a bad FCS
with a non-integral number of octets (Alignment Error). Note that
this definition of jabber is different than the definition in IEEE-
802.3 section 8.2.1.5 (10BASE5) and section 10.3.1.4
(10BASE2). These documents define jabber as the condition
where any packet exceeds 20 ms. The allowed range to detect
jabber is between 20 ms and 150 ms.
Fragments/Undersize Received
- The total number of packets
received that were less than 64 octets in length (excluding fram-
ing bits but including FCS octets).

Alignment Errors
- The total number of packets received that
had a length (excluding framing bits, but including FCS octets) of
between 64 and 1518 octets, inclusive, but had a bad Frame
Check Sequence (FCS) with a non-integral number of octets.
Rx FCS Errors
- The total number of packets received that had a
length (excluding framing bits, but including FCS octets) of
between 64 and 1518 octets, inclusive, but had a bad Frame
Check Sequence (FCS) with an integral number of octets
Overruns
- The total number of frames discarded as this port was
overloaded with incoming packets, and could not keep up with
the inflow.
Received Packets not forwarded
Total
- A count of valid frames received which were discarded
(i.e. filtered) by the forwarding process.
Local Traffic Frames
- The total number of frames dropped in
the forwarding process because the destination address was
located off of this port.
802.3x Pause Frames Received
- A count of MAC Control
frames received on this interface with an opcode indicating the
PAUSE operation. This counter does not increment when the
interface is operating in half-duplex mode.
Unacceptable Frame Type
- The number of frames discarded
from this port due to being an unacceptable frame type.
VLAN Membership Mismatch
- The number of frames dis-
carded on this port due to ingress filtering.
VLAN Viable Discards
- The number of frames discarded on
this port when a lookup on a particular VLAN occurs while that
entry in the VLAN table is being modified, or if the VLAN has
not been configured.
Multicast Tree Viable Discards
- The number of frames dis-
carded when a lookup in the multicast tree for a VLAN occurs
while that tree is being modified.
Reserved Address Discards
- The number of frames discarded
that are destined to an IEEE 802.1 reserved address and are not
supported by the system.

- The number of frames discarded
that are destined for FF:FF:FF:FF:FF:FF when Broadcast Storm
Recovery is enabled.
