Parameter

Description

 

 

Transmit Multicast

The total number of packets that higher-level protocols

Packets

requested be transmitted, and which were addressed to

 

a multicast address at this sub-layer, including those that

 

were discarded or not sent.

 

 

Transmit Broadcast

The total number of packets that higher-level protocols

Packets

requested be transmitted, and which were addressed to

 

a broadcast address at this sub-layer, including those

 

that were discarded or not sent.

 

 

Transmit Discarded

The number of outbound packets which were chosen

Packets

to be discarded even though no errors had been

 

detected to prevent their being transmitted. One

 

possible reason for discarding such a packet could be to

 

free up buffer space.

 

 

Transmit Errors

The number of outbound packets that could not be

 

transmitted because of errors.

 

 

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.

SMC6752AL2 specifications

The SMC Networks SMC6752AL2 is a robust and versatile gigabit Ethernet switch designed to cater to the demands of medium to large enterprise networks. This switch delivers an impressive combination of performance, flexibility, and manageability, making it an ideal solution for businesses seeking to enhance their network infrastructure.

One of the standout features of the SMC6752AL2 is its 48 Gigabit Ethernet ports, allowing for high-speed network connections to a variety of devices such as servers, workstations, and other networked equipment. Additionally, the switch includes 4 SFP (Small Form-factor Pluggable) slots that provide options for connecting to other networking devices via fiber optics, enhancing the versatility of the network configuration.

The SMC6752AL2 supports advanced Layer 2 switching capabilities, which are crucial for efficient data handling and traffic management. With features such as VLAN (Virtual Local Area Network) support, the switch can segment network traffic to improve performance and security while effectively managing broadcast domains. It supports 802.1Q VLAN tagging, allowing for better network segmentation and isolation of different types of traffic.

Moreover, the switch is equipped with Quality of Service (QoS) features to prioritize critical data transmissions. This is essential for applications requiring real-time data flow, such as VoIP (Voice over Internet Protocol) and video conferencing. The SMC6752AL2's QoS capabilities enable users to classify and prioritize traffic, ensuring a smooth and seamless experience for bandwidth-intensive applications.

The SMC6752AL2 also includes features such as port mirroring and link aggregation, enhancing the monitoring and management capabilities of the network. Port mirroring allows administrators to duplicate traffic from one port to another for analysis and troubleshooting, while link aggregation enables combining multiple connections for increased bandwidth and redundancy.

In terms of security, the switch supports802.1X port-based authentication, providing a layer of network access control that ensures only authorized users can connect. This feature, combined with the ability to create access control lists (ACLs), helps to safeguard the network against unauthorized access and other potential threats.

Overall, the SMC Networks SMC6752AL2 is a feature-rich Ethernet switch that offers reliable performance and advanced capabilities for managing enterprise networks. Its combination of port density, layer 2 switching features, QoS functionalities, and enhanced security makes it an excellent choice for organizations looking to expand or upgrade their networking solutions. With the SMC6752AL2, businesses can maintain high-performance connectivity and effective network management tailored to their specific operational needs.
