Table 33 Ethernet statistics for port

Statistics

Description

dot3StatsFrameTooLongs

A count of frames received on a particular interface that exceeds

 

the maximum permitted frame size.

 

The count represented by an instance of this object is incremented

 

when the frameTooLong 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.

dot3StatsInternalMacReceiveErrors

A count of frames for which reception on a particular interface fails

 

due to an internal MAC sublayer receive error.

 

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

 

counted by the corresponding instance of the

 

dot3StatsFrameTooLongs object, the dot3StatsAlignmentErrors

 

object, or the dot3StatsFCSErrors 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 received errors on a particular

 

interface that are not otherwise counted.

Table 34 Interface statistics for port

Statistics

Description

Octets—IfHCIn

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

 

characters.

UcastPkts—IfHCIn

The number of packets, delivered by this sublayer to a higher sublayer, which

 

were not addressed to a multicast or broadcast address at this sublayer.

BroadcastPkts—IfHCIn

The number of packets, delivered by this sublayer to a higher sublayer, which

 

were addressed to a broadcast address at this sublayer.

MulticastPkts—IfHCIn

The total number of packets, delivered by this sublayer. These are the packets

 

that higher-level protocols requested to be transmitted, and which were

 

addressed to a multicast address at this sublayer, including those that were

 

discarded or not sent.

 

For a MAC layer protocol, this includes both group and functional addresses.

Discards—IfHCIn

The number of inbound packets which were chosen to be discarded even though

 

no errors were detected to prevent their being delivered to a higher-layer

 

protocol. One possible reason for discarding such a packet could be to free up

 

buffer space.

Errors—IfHCIn

For packet-oriented interfaces, the number of inbound packets that contained

 

errors preventing them from being delivered to a higher-layer protocol.

 

For character-oriented or fixed-length interfaces, the number of inbound

 

transmission units that contained errors preventing them from being deliverable to

 

a higher-layer protocol.

Octets—IfHCOut

The total number of octets transmitted out of the interface, including framing

 

characters.

NEC N8406-022 manual Interface statistics

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.
