Enabling DST

Setting the System Clock	Managing System Files

When Daylight Savings Time (DST) is enabled, the switch’s clock will automatically set the default DST parameters for the time zone specified on the switch or for the custom parameters you can specify with the system daylight savings time start command. In this case, it is not necessary to change the time setting on the switch when your time zone changes to and from DST. To verify the DST parameters for your switch, use the system daylight savings time command. A screen similar to the following will display:

-> system daylight savings time Daylight Savings Time (DST) is DISABLED.

PST: (Coordinated Universal Time) UTC-8 hours Daylight Savings Time (DST):

DST begins on the first sunday in april (4/7) at 2:00 DST ends on the last sunday in october (10/27) at 2:00 DST will change the time by +/- 1:00 hour(s)

The second line in the above display indicates the Enabled/Disabled status of the DST setting on the switch. The last three lines describe the date and time parameters for the selected time zone or the custom parameters set with the CLI. To enable daylight savings time use the following command:

-> system daylight savings time enable

Note. If your time zone shows “No default” in the “Time Zone and DST Information Table” below under the DST parameters, refer to “Daylight Savings Time Configuration” on page 2-37for information on configuring and enabling DST.

The following table shows a list of supported time zone abbreviations and DST parameters.

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.
