Parameter

Description

 

 

Multiple Collision

A count of successfully transmitted frames for which

Frames

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.

 

 

Internal MAC Receive

A count of frames for which reception on a particular

Errors

interface fails due to an internal MAC sublayer receive

 

error.

 

 

RMON Statistics

 

 

 

Drop Events

The total number of events in which packets were

 

dropped due to lack of resources.

 

 

Jabbers

The total number of frames received that were longer

 

than 1518 octets (excluding framing bits, but including

 

FCS octets), and had either an FCS or alignment error.

 

 

Received Bytes

Total number of bytes of data received on the network.

 

This statistic can be used as a reasonable indication of

 

Ethernet utilization.

 

 

Collisions

The best estimate of the total number of collisions on

 

this Ethernet segment.

 

 

Received Frames

The total number of frames (bad, broadcast and

 

multicast) received.

 

 

Broadcast Frames

The total number of good frames received that were

 

directed to the broadcast address. Note that this does

 

not include multicast packets.

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.
