If you get an error message, check that your IP information has been entered correctly and the Switch is powered up.

3Open your web browser and enter the IP address of the Switch that you wish to manage in the URL locator, for example, in the following format:

http:// xxx.xxx.xxx.xxx

4At the login and password prompts, enter admin as your user name and press Return at the password prompt (or the password of your choice if you have already modified the default passwords).

Setting Up SNMP

Any network management application running the Simple Network

Management

Management Protocol (SNMP) can manage a Switch if:

 

■ The correct Management Information Bases (MIBs) are installed on the

 

management workstation.

 

■ The management workstation is connected to the Switch using a port

 

in VLAN 1 (the Default VLAN). By default, all ports on the Switch are in

 

VLAN 1.

 

You can use the 3Com Network Supervisor application that is provided on

 

the CD-ROM that accompanies your Switch to provide SNMP

 

management for your Switch. If you use 3Com Network Supervisor it

 

automatically loads the correct MIBs and necessary files onto your

 

workstation.

Pre-requisites

■ Documentation supplied with the SNMP network management

 

application software.

 

To manage your Switch using an SNMP network management

 

application, you need to specify SNMP community strings for the users

 

defined on the Switch. You can do this using the command line interface

 

system management snmp community command — refer to the

 

command line interface section of the “SuperStack 3 Switch

 

Management Interface Reference Guide” for more information.

3C17204, 3C172203 specifications

The 3Com 3C172203 and 3C17204 are part of the 3Com series of networking products that have made significant contributions to local area networks (LANs) and enterprise connectivity. While they may not be as widely recognized today as newer technologies, their features, technologies, and characteristics played an essential role in enhancing network performance and reliability during their peak usage.

One of the defining features of the 3Com 3C172203 and 3C17204 is their support for Ethernet networking, which was pivotal in establishing fast and reliable communication between devices on a network. These products typically supported both 10Base-T and 100Base-TX standards, providing a flexible transition from older networks to faster Ethernet speeds. This backward compatibility ensured that organizations could upgrade their networks incrementally without needing a complete overhaul, thereby preserving their existing investments in infrastructure.

Both models also supported features designed to optimize network performance and provide enhanced management capabilities. For instance, built-in diagnostic features enabled network administrators to troubleshoot connection issues more effectively, thereby reducing downtime. Additionally, these devices incorporated intelligent switching capabilities that could manage data flow efficiently, prioritizing traffic and optimizing available bandwidth to ensure a smooth user experience, even under heavy load.

In terms of physical design, the 3C172203 and 3C17204 were built with a focus on durability. These units often featured robust metal enclosures suitable for various environments, from office spaces to more demanding industrial settings. Furthermore, their compact design allowed for easy integration into existing network setups without requiring significant rack space, making them an attractive option for enterprises looking to maximize their networking capabilities.

Security features were also a consideration in the design of these networking devices. They implemented basic security protocols to safeguard the integrity of data transmitted across the network, ensuring that unauthorized access was minimized and overall network security was enhanced.

In conclusion, the 3Com 3C172203 and 3C17204 represent an era of networking technology characterized by their support for Ethernet standards, intelligent switching capabilities, robust design, and essential management features. These products were integral in facilitating the growth of LANs and laid the groundwork for the advanced networking solutions that followed in the years ahead. While newer technologies have emerged since then, the fundamental principles established by devices like the 3C172203 and 3C17204 continue to influence contemporary networking designs.
