Chapter 5 Correlation Over Unmanaged Segments

Cloud Problem Alarm

Cloud Problem Alarm

For some events, when there is no root cause found, a special cloud problem alarm is created. These events are then correlated to the alarm. The cloud problem alarm has a major severity, and is automatically cleared after a delay.

Note When required a correlation filter, filters the cloud problem. This enables or disables the ability of an alarm to create a cloud problem alarm, and to correlate to it. The default value is false for all alarms in the system, meaning that an alarm does not correlate to the cloud problem alarm by default. However, there are several alarms that override the default configuration and are set to true, as follows:

BGP neighbor down syslog OSPF neighbor loss syslog

EIGRP router query to neighbors timeouted syslog ipx 3 bad igrp sap syslog

Cloud Correlation Example

In this example, two devices that have OSPF configured are connected through a cloud. A malfunction occurs inside the unmanaged network that causes the OPSF neighbor down alarm to be generated. In this case the OSPF neighbor down alarm is correlated to the cloud problem.

State "down"

On the PE1 device, the OSPF neighbor down alarm was received, and no root cause was detected in any of the managed devices. A disconnected link inside the unmanaged network caused the OSPF neighbor down alarm. The following alarms are generated and correlated:

OSPF neighbor down on the PE1 is correlated to the cloud problem alarm.

It incorporates Cisco's SecureX framework, which provides centralized visibility and control across the entire security stack. This feature allows organizations to respond rapidly to threats, leveraging threat intelligence and automated response mechanisms to mitigate risks effectively.

Another notable characteristic is improved compatibility with cloud environments. With the rise of hybrid cloud models, Cisco Systems 3.6 offers seamless integration capabilities that enable businesses to connect their on-premises networks with public and private cloud infrastructures. This ensures greater flexibility and enhanced performance for cloud-based applications.

Cisco also emphasizes software-defined networking (SDN) with its updated platform. This approach allows for greater agility, enabling network administrators to programmatically manage resources through a centralized interface. SDN facilitates rapid deployment of services and applications, optimizing the overall user experience.

Cisco Systems 3.6 also boasts enhanced collaboration tools, fostering improved communication across teams. Featuring advanced video conferencing and messaging capabilities, it enhances productivity and streamlines processes, regardless of employee location. These tools are designed to support remote work environments, which have become increasingly important in today's business landscape.

Furthermore, energy efficiency is a core aspect of Cisco Systems 3.6. The system is designed to optimize power consumption and reduce overall operating costs, aligning with global sustainability goals. The efficient design prioritizes environmentally friendly practices while still delivering high performance.

In conclusion, Cisco Systems 3.6 represents a comprehensive evolution in networking technology, focusing on automation, security, cloud integration, SDN, collaboration, and energy efficiency. These features position Cisco as a pivotal player in supporting organizations as they navigate the complexities of digital transformation and the future of networking.
