5-16 CHAPTER 5: ADDITIONAL MANAGEMENT USING VT100

The access levels are defined as:

■Monitor — This allows the user to view the essential operations of the hub and to establish whether or not the hub is operating correctly. A user at this level cannot change the operating parameters of the hub.

■Secure Monitor — In this implementation, Secure Monitor has the same rights as Monitor.

■Manager — This allows the user to monitor and change the operational parameters of the hub. The user cannot create or delete other users, re-initialize the hub or download a software image.

■Specialist — In this implementation, Specialist has the same rights as Manager.

■Security — This allows the user to access all the management operations. This level of security should be assigned only to the system administrator or somebody with the system administrator’s responsibilities.

To prevent you from locking yourself out from the hub completely, console port access is always kept enabled for the security access level.

Console Port Enabled / Disabled

To prevent access to the management facilities through the console port, disable access to the facility for each access level. To allow you to configure the hub locally in the event of problems on your network, we suggest that you change the default password for the permanently-enabled security access level, see “Editing Users” on

page 5-18.

Remote Telnet Enabled / Disabled

Telnet is an insecure protocol. You may wish to disable all access to the management facilities through Telnet if there is important or secret data on your network.

Community SNMP Enabled / Disabled

The hub can be managed through SNMP using a remote network manager. Community SNMP does have some simple security features but it is an insecure protocol. You may wish to disable all access to the management facilities through Community SNMP if there is important or secret data on your network.

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.
