Statistics

Description

dot3StatsAlignmentErrors

A count of frames received on a particular interface that are not an

 

integral number of octets in length and do not pass the Frame

 

Check Sequence (FCS) check.

 

The count represented by an instance of this object is incremented

 

when the alignmentError status is returned by the MAC service to

 

the Logical Link Control (LLC) (or other MAC user).

 

Received frames for which multiple error conditions obtained are,

 

according to the conventions of IEEE 802.3 Layer Management,

 

counted exclusively according to the error status presented to the

 

LLC.

dot3StatsFCSErrors

A count of frames received on a particular interface that are an

 

integral number of octets in length but do not pass the Frame

 

Check Sequence (FCS) check.

 

The count represented by an instance of this object is incremented

 

when the frameCheckError status is returned by the MAC service to

 

the LLC (or other MAC user).

 

Received frames for which multiple error conditions obtained are,

 

according to the conventions of IEEE 802.3 Layer Management,

 

counted exclusively according to the error status presented to the

 

LLC.

dot3StatsSingleCollisionFrames

A count of successfully transmitted frames on a particular interface

 

for which transmission is inhibited by exactly one collision.

 

A frame that is counted by an instance of this object is also counted

 

by the corresponding instance of the ifOutUcastPkts,

 

ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the

 

corresponding instance of the dot3StatsMultipleCollisionFrame

 

object.

dot3StatsMultipleCollisionFrames

A count of successfully transmitted frames on a particular interface

 

for which transmission is inhibited by more than one collision.

 

A frame that is counted by an instance of this object is also counted

 

by the corresponding instance of either the ifOutUcastPkts,

 

ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the

 

corresponding instance of the dot3StatsSingleCollisionFrames

 

object.

dot3StatsLateCollisions

The number of times that a collision is detected on a particular

 

interface later than 512 bit-times into the transmission of a packet.

 

Five hundred and twelve bit-times corresponds to 51.2

 

microseconds on a 10 Mbit/s system. A (late) collision included in a

 

count represented by an instance of this object is also considered

 

as a (generic) collision for purposes of other

 

collision-related statistics.

dot3StatsExcessiveCollisions

A count of frames for which transmission on a particular interface

 

fails due to excessive collisions.

dot3StatsInternalMacTransmitError

A count of frames for which transmission on a particular interface

s

fails due to an internal MAC sublayer transmit error.

 

A frame is only counted by an instance of this object if it is not

 

counted by the corresponding instance of either the

 

dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions

 

object, or the dot3StatsCarrierSenseErrors object.

 

The precise meaning of the count represented by an instance of

 

this object is implementation specific. In particular, an instance of

 

this object may represent a count of transmission errors on a

 

particular interface that are not otherwise counted.

N8406-022 specifications

The NEC N8406-022 is a robust and versatile networking device designed primarily for organizations requiring high-performance connectivity solutions. As part of NEC's extensive portfolio of networking equipment, the N8406-022 is engineered to address the demands of modern enterprise environments, ensuring seamless communication and data processing capabilities.

One of the key features of the N8406-022 is its multi-layer switching functionality. This device supports Layer 2 and Layer 3 switching, allowing for efficient data routing and reducing latency within local area networks (LANs). This capability is particularly beneficial for businesses that rely on real-time data access and transfer, such as those in financial services, media, and telecommunications.

The N8406-022 is equipped with advanced Quality of Service (QoS) features that help prioritize critical network traffic. This means that voice and video data packets can be given precedence over less time-sensitive information, ensuring that essential communication remains clear and uninterrupted. This is crucial for organizations leveraging VoIP and video conferencing solutions.

In terms of connectivity, the NEC N8406-022 offers a variety of ports, including multiple Gigabit Ethernet ports, which facilitate high-speed data transfer and enable seamless integration into existing network infrastructures. The device may also include 10 Gigabit SFP+ ports, providing the flexibility for high-capacity uplinks to support bandwidth-intensive applications and storage solutions.

Security is another focal point of the NEC N8406-022, with integrated features such as VLAN support, access control lists (ACLs), and port security measures. These capabilities protect sensitive data from unauthorized access and ensure that only legitimate users and devices can connect to the network.

Moreover, the N8406-022 often incorporates advanced energy-efficient technologies that minimize power consumption without compromising performance. This not only contributes to operational cost savings but also supports organizations in their sustainability efforts.

With its combination of performance, security, and energy efficiency, the NEC N8406-022 stands out as a reliable networking solution suitable for a wide range of enterprises looking to enhance their connectivity and operational efficiency. Whether deployed in data centers or as part of a corporate network, this device is built to meet the evolving demands of today’s digital landscape.
