10CHAPTER 1: INITIAL CONFIGURATION

IP Configuration 3Com recommends that you define the IP configuration using the

/etc/hosts files on the two systems.

The /etc/hosts file on each server must contain identical information about the Intelligent Mirroring configuration. Other information in the file may vary. The examples in this document contain the information that must be identical.

For each network to which Intelligent Mirroring is connected, you must configure four unique IP addresses, all on the same subnetwork:

Two of these addresses are static and are assigned to the primary network interface cards on the two systems.

The other two IP addresses are aliases that are dynamically assigned based on the state (active versus standby) of the Intelligent Mirroring servers. These addresses are not associated with any hardware.

Single Network To configure both the Primary and Secondary servers on a single network, Configuration follow the instructions in this section. For the instructions on how to

configure the servers on two networks, see Dual Network Configuration.

3Com recommends that you configure the systems on which Intelligent Mirroring runs so that each one is connected to two independent networks on separate switches. This provides additional reliability should problems develop on either network (for example, if a switch fails). See Figure 1 on page 12.

The examples in this section are based on these assumptions:

System 1 (Primary Server)

System Name — voipbox1

IP Address (subnetwork 126) — 192.168.126.1 (associated with the primary network interface on the Primary Server)

System 2 (Secondary Server)

System Name — voipbox2

IP Address (subnetwork 126) — 192.168.126.2 (associated with the primary network interface on the Secondary Server)

V7300 specifications

The 3Com V7300 is a sophisticated network switch designed to cater to the demands of modern enterprise networking. With its robust feature set and advanced capabilities, it is positioned as a critical component in delivering high-performance connectivity.

One of the key features of the 3Com V7300 is its high port density. The switch supports a variety of port configurations, allowing for 10/100/1000 Mbps Ethernet connections. This flexibility ensures that organizations can scale their networks with ease, adapting to growing bandwidth requirements without compromising performance. Additionally, the switch can accommodate both copper and fiber connections, ensuring compatibility with existing infrastructure.

A standout technology integrated into the 3Com V7300 is its support for Layer 3 routing. This allows for intelligent traffic management and enhanced data routing within complex network environments. With Layer 3 functionality, organizations can segment their networks for improved security and performance, as well as enable inter-VLAN routing. This capability is critical for businesses looking to optimize their network efficiency while ensuring secure communication between different network segments.

The V7300 also boasts advanced Quality of Service (QoS) features. This technology prioritizes critical applications and services, ensuring that voice and video traffic receive the bandwidth they require for uninterrupted performance. By implementing QoS policies, organizations can enhance user experience, especially in environments where real-time communications are essential.

Reliability is a cornerstone of the 3Com V7300's design, featuring redundancy options such as dual power supplies and fan units. This ensures that the switch remains operational even in the event of hardware failures, minimizing downtime and maintaining service continuity. The robust management capabilities, including SNMP support, allow IT administrators to monitor the network effectively and respond to issues proactively.

Security features are also a significant consideration with the V7300. It includes access control lists (ACLs), port security, and VLAN support to restrict access and protect sensitive data from unauthorized users. Further, the integration of 802.1X authentication enhances network security by ensuring that only authorized devices can access the network.

In conclusion, the 3Com V7300 stands out as a high-performance network switch suitable for enterprises seeking to future-proof their networking capabilities. With its high port density, Layer 3 routing, advanced QoS, reliability, and robust security measures, it is a solid choice for businesses looking to enhance their network infrastructure.
