70CHAPTER 3: SETTING UP FOR MANAGEMENT

(where xxx.xxx.xxx.xxx is the IP address of the switch)

If you are opening a Telnet session using third party software, you must enter the IP address in the format suitable for that software.

5At the Username prompt, enter admin as your user name and press Return. At the password prompt press Return again. (or enter the password if you have modified the default passwords).

If the login prompt does not display immediately, press Return a few times until it starts.

6If you have logged on correctly, the switch prompt display as <5500G-EI>or <5500-xx>(where xx is either SI or EI, as shown in Figure 27 on page 63).

Setting Up Command Line Interface Management using

SSH

This section describes to can set up command line Interface management using SSH over a network.

To manage a switch through the command line interface over a network using SSH:

1Ensure that you have set up the switch with IP information as described in “Methods of Managing a Switch” on page 56.

2Check that you have the IP protocol correctly installed on your management workstation. You can check this by trying to browse the World Wide Web. If you can browse, the IP is installed correctly.

3Check that you can communicate with the switch by entering a ping command at the DOS prompt in the following format:

c:\ ping xxx.xxx.xxx.xxx

(where xxx.xxx.xxx.xxx is the IP address of the switch)

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

The switch automatically generates a host key pair when it is powered up for the first time, or after any reset to factory defaults. Host key generation may take a while, during which time SSH connections to the switch will be refused.

4Install an SSH client application on the workstation from which you want to use to access the switch.

3Com recommends the PuTTY, OpenSSH, and SSH Communications Security Corp Secure Shell SSH clients.

3Com 5500G-EI Setting Up Command Line Interface Management using, Where xxx.xxx.xxx.xxx is the IP address of the switch

5500G-EI, 5500-EI specifications

The 3Com 5500-EI and 5500G-EI series are advanced Ethernet switches designed for enterprise networks, catering to the growing demand for high-performance, secure, and scalable networking solutions. These switches are particularly suited for large organizations that require robust management capabilities and high-density connectivity.

One of the key features of the 5500-EI and 5500G-EI models is their modular architecture, which allows businesses to tailor the switch configuration to their specific needs. With options for various interface modules, including Gigabit Ethernet and PoE (Power over Ethernet), these switches can support diverse networking requirements and facilitate the gradual expansion of the network infrastructure.

The Series offers advanced Layer 2 and Layer 3 switching capabilities. Layer 2 features include VLAN tagging, trunking, and Spanning Tree Protocol (STP) to ensure efficient traffic management and network segmentation. On the Layer 3 front, the switches support static routing, RIP, and OSPF, enabling dynamic routing protocols for better traffic flow and load balancing. These features together enhance the performance and reliability of enterprise applications.

Security is another vital aspect of the 3Com 5500-EI and 5500G-EI series. The switches come equipped with robust security features to protect sensitive data and maintain compliance. These include MAC address filtering, access control lists (ACLs), and support for 802.1X authentication. Additionally, the devices support secure management protocols like SNMP v3, which enhances the security of management communications.

The 5500G-EI model stands out with its high-density port offerings, supporting up to 48 ports in a single switch, with an option for stacking to create a unified management platform across multiple switches. This flexibility allows organizations to leverage their existing infrastructure while scaling seamlessly in response to growing demands.

Another notable characteristic is the built-in IPv6 support, which positions the 3Com 5500-EI and 5500G-EI models favorably for future-proofing enterprise networks as the transition to IPv6 continues. This feature ensures that organizations can maintain connectivity as devices increasingly adopt the newer protocol.

In conclusion, the 3Com 5500-EI and 5500G-EI series offer a comprehensive suite of features and technologies designed for high-performance enterprise networking. With modularity, robust Layer 2 and Layer 3 capabilities, enhanced security measures, and a focus on scalability, these switches provide a solid foundation for modern corporate networks, accommodating future growth and technological advancements.
