alarmIndex—An index that uniquely identifies an entry in the alarm table. Each such entry defines a diagnos- tic sample at a particular interval for an object on the device.

alarmVariable—The object identifier of the particular variable to be sampled. Only variables that resolve to an ASN.1 primitive type of INTEGER (INTEGER, Integer32, Counter32, Counter64, Gauge, or TimeTicks) may be sampled.

alarmSampleType—The method of sampling the selected variable and calculating the value to be compared against the thresholds. If the value of this object is absoluteValue(1), the value of the selected variable will be compared directly with the thresholds at the end of the sampling interval. If the value of this object is deltaValue(2), the value of the selected variable at the last sample will be subtracted from the current value, and the difference compared with the thresholds.

alarmValue—The value of the statistic during the last sampling period. For example, if the sample type is deltaValue, this value will be the difference between the samples at the beginning and end of the period. If the sample type is absoluteValue, this value will be the sampled value at the end of the period. alarmRisingThreshold—A threshold for the sampled statistic. When the current sampled value is greater than or equal to this threshold, and the value at the last sampling interval was less than this threshold, a single event will be generated. A single event will also be generated if the first sample after this entry becomes valid is greater than or equal to this threshold and the associated alarmStartupAlarm is equal to risingAlarm(1) or risin- gOrFallingAlarm(3).

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.
