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).

Check Sequence (FCS) with a non-integral number of octets.

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.

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.
