4-20 CHAPTER 4: MANAGING YOUR HUB USING QUICK CONFIG MANAGER

Total Errors Shows the total number of errors that have occurred per poll, it should be a small percentage of the readable frames figure.

Runts Shows the number of frames received with octet counts less than the minimum legal size

(512 bits), which were not involved in a collision on the segment being monitored. Runt frames are the result of collisions on other segments and are propagated around the network; this is a normal part of Ethernet operation. An excessive number of runts or collisions is an indication of congestion. You may need to consider segmenting your network (separating the busiest parts).

Readable Shows the number of frames received that are of valid length and have not suffered a collision or FCS error. Look for unusual increases in traffic rate; this can indicate a potential problem.

Broadcast Shows the number of frames received which are addressed to all devices. The number of broadcast frames is normally a small percentage of the value seen for unicast (single address) frames.

A high level of broadcast frames can adversely affect network performance.

Collisions Shows the number of frames for which a transmission collision was detected. Collisions are a normal part of Ethernet operation and occur if two or more devices attempt to transmit at the same time. A sudden sustained increase in the number of collisions can indicate a problem with a device, particularly if it is not accompanied by a general increase in traffic. On coaxial segments an increase in collisions can also indicate faulty cabling.

The values shown in the Activity/Errors graph are per poll period, not per second. To change the poll period, see “Accessing the Hub” on page 4-6.

3C16710 specifications

The 3Com 3C16710 is a high-performance networking device that stands out in the realm of network communication solutions, delivering reliability and efficiency for a variety of network environments. Positioned as a part of 3Com's robust product line, the 3C16710 is designed to facilitate seamless connectivity, catering to the needs of small to medium-sized enterprises.

One of the standout features of the 3C16710 is its advanced Layer 2 switching capabilities. Built to support multiple Ethernet standards, this switch is equipped with 10/100BASE-TX ports, allowing for flexible integration into existing network infrastructures. With a switching capacity that ensures minimal latency, the 3C16710 is capable of handling substantial data traffic, making it an ideal choice for organizations that demand high-speed connectivity.

The device supports advanced features such as VLAN (Virtual Local Area Network) tagging, which effectively enhances network efficiency by segmenting network traffic. This capability helps to optimize bandwidth usage and improve security by isolating sensitive data traffic. Moreover, it supports spanning tree protocol to prevent loops, facilitating a stable and trouble-free network experience.

In terms of management, the 3C16710 provides various options for configuration and monitoring. It supports both SNMP (Simple Network Management Protocol) for network management as well as a web-based interface for intuitive access, allowing network administrators to easily manage settings and monitor performance. The switch can be configured to deliver quality of service (QoS), ensuring that critical applications receive the bandwidth they require, thereby improving overall network performance.

Another noteworthy characteristic is its robust build quality, which enhances reliability in challenging environments. The 3C16710 is also designed for energy efficiency, complying with green networking standards to minimize power consumption without sacrificing performance.

In summary, the 3Com 3C16710 is a versatile networking switch that combines advanced Layer 2 switching capabilities, VLAN support, and flexible management options. With its reliable performance and energy-efficient design, it meets the demands of modern network architectures, making it a valuable asset for organizations looking to enhance their network infrastructure.
