Port Configuration

 

 

Parameter

Description

 

 

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.

Fragments

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

 

(excluding framing bits, but including FCS octets) and had either an FCS

 

or alignment error.

Accton Technology VS4512DC manual Parameter Description, Rmon Statistics

VS4512DC, VS4512 specifications

Accton Technology is renowned for its innovative networking solutions and has made significant strides in the realm of networking devices with its VS4512 and VS4512DC models. These devices cater primarily to the advanced needs of enterprise and data center environments, providing robust features and cutting-edge technologies that enhance network performance and reliability.

The Accton VS4512 is a high-performance Layer 2+ switch designed for top-of-rack applications in data centers. It boasts a compact 1U design, making it highly efficient for space-constrained environments. One of its standout features is the support for Ethernet Flow Control, which significantly reduces data loss during peak traffic loads. This is essential for businesses that rely on real-time data processing and streaming.

In terms of scalability, the VS4512 supports up to 48 Gigabit Ethernet ports, which can be expanded using four 10 Gigabit SFP+ uplink ports. This flexibility allows enterprises to customize their network architecture to meet their growing demands, whether they are scaling up for more users or enhancing service capabilities.

The VS4512DC, on the other hand, is the DC version tailored for data centers. It offers similar features as the VS4512 but includes enhancements for power efficiency and redundancy, ensuring that operations can continue smoothly even in power outage scenarios. The VS4512DC features dual power supplies and advanced thermal management, allowing for improved heat dissipation and lower operational costs.

Both models support advanced Layer 3 routing capabilities, enabling efficient traffic management across complex networks. They also incorporate features like VLAN segmentation and link aggregation, which facilitate better bandwidth utilization and improved network security.

Security is another cornerstone of these switches, with features such as DHCP snooping, port security, and storm control to mitigate risks associated with unauthorized access and network congestion.

In summary, the Accton Technology VS4512 and VS4512DC switches represent significant advancements in networking technology, equipped with a comprehensive set of features tailored for modern enterprise needs. With their scalability, robust performance, and focus on security, these switches are positioned to meet the challenges of today's fast-paced digital environments, making them a preferred choice for organizations aiming to enhance their network infrastructure.
