The example answers in this script assume that you are using voipbox2,

 

that voipbox2 will be the secondary server, and that voipbox1 will be the

 

primary server.

 

Intelligent Mirroring configurations

 

Should Intelligent Mirroring be enabled (Y/N)? [N]: Y

 

Name of the Remote Intelligent Mirrored System? : voipbox1

 

Intelligent Mirroring Alias? : active

 

Is this host the primary or the secondary (P/S)? : S

 

Enter the Device Name of the Network Card? : eth0

 

Enter the Device Name of the Second Network Card, enter if

 

only one? eth1

 

Enter the Standby Alias? : standby

 

The Secondary Server now restarts itself and picks up the Line and Port

 

configuration from the Primary Server.

 

The portion of the firstboot script that deals with UMS Intelligentigent

 

Mirroring has now been completed. The firstboot script continues

 

with other configuration questions.

 

 

Intelligent

Intelligent Mirroring uses one of two policies to determine which server

Mirroring

operates in the active state and which operates in the standby state. The

Active/Standby

Primary and Balanced policies, explained next, control the two server

Policy

states.

 

The example answers in this script assume that you are using voipbox1,

 

that voipbox1 will be the primary server, and that voipbox2 will be the

 

secondary server.

 

Configuration of a mirroring policy can be done only after the firstboot

 

script has been completed and the VCX system has been rebooted.

Primary Intelligent

This policy specifies that whenever the Primary Server is running, it enters

Mirroring Policy

the active state. If the Secondary Server was running in the active state,

 

the two servers negotiate so that the Secondary Server switches to the

 

standby state.

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.
