Parameter

Description

 

 

Etherlike Statistics

 

 

 

Alignment Errors

The number of alignment errors (missynchronized

 

data packets).

 

 

Late Collisions

The number of times that a collision is detected later

 

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

 

 

FCS Errors

A count of frames received on a particular interface

 

that are an integral number of octets in length but do

 

not pass the FCS check. This count does not include

 

frames received with frame-too-long or

 

frame-too-short error.

 

 

Excessive Collisions

A count of frames for which transmission on a

 

particular interface fails due to excessive collisions.

 

This counter does not increment when the interface is

 

operating in full-duplex mode.

 

 

Single Collision Frames

The number of successfully transmitted frames for

 

which transmission is inhibited by exactly one

 

collision.

 

 

Internal MAC Transmit

A count of frames for which transmission on a

Errors

particular interface fails due to an internal MAC

 

sublayer transmit error.

 

 

Multiple Collision Frames

A count of successfully transmitted frames for which

 

transmission is inhibited by more than one collision.

 

 

Carrier Sense Errors

The number of times that the carrier sense condition

 

was lost or never asserted when attempting to transmit

 

a frame.

 

 

SQE Test Errors

A count of times that the SQE TEST ERROR

 

message is generated by the PLS sublayer for a

 

particular interface.

 

 

Frames Too Long

A count of frames received on a particular interface

 

that exceed the maximum permitted frame size.

 

 

Deferred Transmissions

A count of frames for which the first transmission

 

attempt on a particular interface is delayed because the

 

medium was busy.

SMC6824M specifications

The SMC Networks SMC6824M is a robust and reliable managed switch that caters to the needs of small to mid-sized businesses, as well as enterprise environments. This switch is designed to provide enhanced performance, scalability, and security for network infrastructures that require efficient traffic management and comprehensive control.

One of the key features of the SMC6824M is its 24 10/100/1000BASE-T ports, which offer lightning-fast Ethernet connectivity. These ports are capable of auto-negotiation, allowing devices to automatically adjust their settings for optimal performance, making it easier to integrate various hardware into existing networks. Additionally, the switch includes four Gigabit SFP slots for fiber uplinks, which allow for extended connectivity options and improved network design.

The SMC6824M employs advanced Layer 2 and Layer 3 functionalities, giving network administrators the tools they need to manage their networks effectively. It supports features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS), ensuring efficient bandwidth management and enhanced performance for critical applications. Through VLAN segmentation, it can isolate network traffic for different departments or functions, enhancing security and reducing congestion.

The switch also offers comprehensive network management capabilities through SNMP (Simple Network Management Protocol) and a web-based interface, enabling easy configuration, monitoring, and troubleshooting. The SMC6824M includes support for port mirroring, which is important for diagnostics and monitoring network performance.

Another significant characteristic of the SMC6824M is its redundancy features, which include IEEE 802.1d Spanning Tree Protocol (STP) to prevent loops and provide network resilience. This is essential for maintaining continuous operation, especially in dynamic environments where network availability is critical.

In terms of security, the SMC6824M supports 802.1X port-based authentication, ensuring that only authorized devices gain access to the network. This feature is crucial for protecting sensitive data and maintaining the integrity of the network.

Overall, the SMC Networks SMC6824M is a versatile and feature-rich managed switch that delivers the performance and flexibility required to support growing networks. Its combination of layer management, security features, and user-friendly interface makes it an excellent choice for organizations looking to enhance their network infrastructure.
