Scenario 3: Synchronizing Switches in a Stack

When changes have been made to the primary CMM switch certified directory, these changes need to be propagated to the other switches in the stack. This could be done by completely rebooting the stack. However, a loss of switch functionality is to be avoided, a copy flash-synchrocommand can be issued.

The following diagram illustrates the process that occurs when using a copy flash-synchro command. The stack shown is a three switch stack.

1.A copy flash- synchro com- mand is issued on the primary CMM switch.

2.The contents of the certified direc- tory of the primary CMM switch are copied to the working directory of the secondary CMM switch. The working directory is then copied to the certified direc- tory.

3.The contents of the certified direc- tory of the pri- mary CMM switch are copied to the working directory of additional switches. The working directory is then copied to the certified direc- tory.

Synchronizing Switches in a Stack

The copy flash-synchrocommand (described in “Synchronizing the Primary and Secondary CMMs” on page 4-26) can be issued on its own, or in conjunction with the copy working certified command (described in “Copying the Working Directory to the Certified Directory” on page 4-25).

Note. It is important to certify the working directory and synchronize the stack as soon as the validity of the software is established. Stacks booted from the working directory or unsynchronized stacks are at risk of mismanaging data traffic due to incompatibilities in different versions of switch software. Certifying the working directory is described in “Copying the Working Directory to the Certified Directory” on page 4-20, while synchronizing the switch is described in “Synchronizing the Primary and Secondary CMMs” on page 4-26.

omniswitch specifications

Alcatel Carrier Internetworking Solutions offers the OmniSwitch series, renowned for its robust capabilities in delivering high-performance networking solutions tailored for a variety of enterprise and service provider environments. The OmniSwitch series is particularly recognized for its scalability, flexibility, and the depth of its feature set, making it a popular choice for organizations that demand reliable and efficient networking solutions.

One of the standout features of the OmniSwitch series is its advanced Layer 2 and Layer 3 switching capabilities, providing organizations with essential support for IP routing and robust Ethernet networking. This versatility ensures that the switch can seamlessly integrate into existing network architectures, facilitating smooth upgrade paths in response to evolving business needs. The OmniSwitch includes support for multiple protocols like RIP, OSPF, and BGP, making it suitable for complex networking topologies.

In terms of performance, OmniSwitch devices are engineered to handle high bandwidth demands. With features such as hardware-based forwarding, they ensure low latency and minimal packet loss, which are critical for applications sensitive to delays such as VoIP and video conferencing. Furthermore, they support Power over Ethernet (PoE), allowing users to power devices like IP phones and security cameras directly through the network.

Security is another key characteristic of the OmniSwitch series. It includes advanced security features such as robust access control lists (ACLs), port security, and built-in support for IEEE 802.1X authentication. These features collectively enhance the security posture of the network, protecting sensitive data and ensuring that only authorized devices can access the network resources.

The OmniSwitch is also designed with redundancy and reliability in mind. Features like Rapid Spanning Tree Protocol (RSTP) and Virtual Router Redundancy Protocol (VRRP) ensure that network uptime is maximized and that failover is swift in the event of a hardware failure. This makes it a viable option for organizations that cannot afford downtime.

In addition to these features, Alcatel's OmniSwitch series comes equipped with a user-friendly management interface. This interface simplifies the setup, configuration, and monitoring of the network, making it accessible even to those with limited networking expertise. Through intuitive dashboards and support for SNMP, administrators can manage their networks effectively.

In conclusion, Alcatel Carrier Internetworking Solutions' OmniSwitch series offers a comprehensive suite of features tailored to meet the needs of modern networks. With its blend of performance, scalability, security, and ease of management, the OmniSwitch stands out as a preferred choice for businesses seeking to enhance their networking infrastructure.
