Parameter

 

Description

 

 

 

 

 

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 Errors

 

A count of frames for which transmission on a 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.

 

Internal MAC Receive Errors

 

A count of frames for which reception on a particular 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.

 

Multicast Frames

 

The total number of good frames received that were directed to this

 

 

 

multicast address.

 

CRC/Alignment Errors

 

The number of CRC/alignment errors (FCS or alignment errors).

 

 

 

 

 

Undersize Frames

 

The total number of frames received that were less than 64 octets long

 

 

 

(excluding framing bits, but including FCS octets) and were otherwise well

 

 

 

formed.

 

Oversize Frames

 

The total number of frames received that were longer than 1518 octets

 

 

 

(excluding framing bits, but including FCS octets) and were otherwise well

 

 

 

formed.

The switch includes support for IEEE 802.1Q VLAN tagging, which allows users to create separate virtual networks for improved traffic management and enhanced security. By segregating network traffic, businesses can optimize bandwidth usage and reduce congestion, contributing to overall increased network performance.

Additionally, the GSW-2692 supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), ensuring loop-free network topology. This capability is crucial in larger networking environments where multiple switches are interconnected, as it prevents broadcast storms and enhances network resilience. The switch also includes features such as port mirroring, which provides administrators with the capability to monitor network traffic in real-time for troubleshooting and analysis.

Power over Ethernet (PoE) support is another significant advantage of the GSW-2692. With PoE functionality, it enables the switch to deliver electrical power along with data to connected devices such as IP cameras, VoIP phones, and wireless access points, eliminating the need for additional power sources and simplifying installations.

In terms of physical characteristics, the LevelOne GSW-2692 is designed for efficient heat dissipation and features a fanless design, which ensures silent operation. Its desktop or rack-mountable options make it flexible for various installation environments. The switch also features a web-based management interface, which simplifies the configuration and monitoring processes, allowing for intuitive management of network settings.

Overall, the LevelOne GSW-2692 stands out as a feature-rich, reliable, and high-performance networking solution that meets the demands of modern enterprises. Its combination of advanced technologies, scalability, and ease of use makes it an excellent choice for businesses looking to enhance their network infrastructure.
