Manual Switchover You can manually switch either server to the active or standby state, provided that you have root privileges.

1In a command window, enter this command:

xattach app

2In the screen that appears, click one of these two items to command the system to switch state:

■Scripts/Spawn vssu_active

■Scripts/Spawn vssu_stanby

3In the Intelligent Mirroring Status window, verify that the state changes appear immediately.

4In the Message window, verify that the messages indicate the progress of the switchover.

Example:

The following message window sequence is typical when you command the active server to go to standby mode:

../app_ss.c:137 Request to become standby

../app_ss.c:193 Remote end has requested to become active

Shutdown from msg4

This side is standby

VSSI_STNDBY vm_nanch=29028

Verifying Server You can verify that the databases and the file systems on the Primary and

Synchronization Secondary Servers are synchronized.

Database To verify database synchronization, at the command line, enter this command:

tblcmp

If the databases are synchronized, you see this message:

Tables are identical

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.
