The default is 60 seconds for the keepalive time and seconds for the hold time. The API is also atomic. The default value is 0 minutes, and the valid range is from 0 to minutes. Domain objects whose names are not “infra” or “common”:. This statement can be used by itself or applied after the query-target statement. In Figure 3, the example object has three processes that write to property chunks in the object. All objects in the tree exist under the root object. Book Description The definitive deep-dive guide to hardware and software troubleshooting on Cisco Nexus switches The Cisco Nexus platform and NX-OS switch operating system combine to deliver unprecedented speed, capacity, resilience, and flexibility in today’s data center networks.
For example, this severity could indicate that the managed object is out of service and its capability must be restored. Every managed object in the system can be identified by a unique distinguished name DN. By posting data to the tacacsext. For a fault object class, the fault conditions are defined by the fault rules of the parent object class. The as-set keyword generates autonomous system set path information and community information from contributing paths. Use this command if you have disabled graceful restart but you still want to enable graceful restart helper functionality.
A basic routinv or inequality test is expressed as follows:. Throughout, you’ll find commwnd configurations, intuitive illustrations, and practical insights into key platform-specific behaviors.
When any MO is created, changed, or deleted because of a user- or system-initiated action, an event is generated. Used only for events. These systems worked well in a world of static network configurations, static workloads, and predictable slower change rates for application scaling. The example in this section queries user information for a user named “test.

The path advertised for this nnx-os is an autonomous system set that consists of all elements contained in all paths that are being summarized:. The default timeout interval is 5 seconds and the range is from 1 to 60 seconds. Places the router in address family configuration mode and specifies unicast address prefixes for the IPv4 address family. Figure 2 below shows an example of this relationship. Compiled Fri Jul Posting this data is equivalent to issuing several tacacs-server commands, for example.
You can specify one or more of the following categories in a comma-separated list with no spaces:.
Some commonly used REST clients are:. This model is a formal specification understood by network planners and developers that is rendered into a running system. Any given nxeus may have several processes that access it.
A service-affecting condition that requires urgent corrective action. Verify the HTTP status code: For example, this severity could indicate that the detected alarm condition is not currently degrading the capacity of the managed object.
You can specify a server object and set the configuration for it. All objects in the tree exist rrouting the root object. This call returns a cookie value that the browser uses for the next calls.
Troubleshooting Cisco Nexus Switches and NX-OS, First Edition [Book]
This example returns aaa: The range seties from 1 to If the same condition is detected multiple times while the corresponding fault MO is active, no additional instances of the fault MO are created. In addition, the northbound management clients get notified about faults and events in a proactive refeernce once they subscribe to interested events.
Critical services could not be started. The above figure depicts the distinguished name, which uniquely represents any given managed object instance, and the relative name, which represents it locally underneath its parent managed object.
Figure 1 depicts the logical hierarchy of the Nc-os object model. In addition to its distinguished name, each object can be referred to by its relative name RN. All properties of the record are set at the time the record object is routign. An event MO is deleted by the rotation of the event log as newer events are added and log space is needed.
For example, this severity could indicate a severe degradation in the capability of the managed object and that its full capability must be restored. In most cases, a fault MO is automatically created, escalated, DE-escalated, and deleted by the system as specific conditions are detected.
Issue an NX-OS show command that shows uniast result of the command or commands that you used to enable configuration settings.
Cisco DevNet: NX-OS – n3k-n9k-api-ref
You must manually reset the BGP sessions after using this command. Domain objects whose names are not “infra” or “common”:. This statement can be used by itself or applied after the query-target statement. With Safari, you learn the way you learn best. The default value is 0 minutes, and the commanx range is from 0 to minutes. When child objects srries to be returned, this statement specifies additional contained objects or options to be included in the response.
An action should be taken to further diagnose, if necessary, and correct the problem to prevent it from becoming a more serious service-affecting fault. An event notification from the subscription delivers a data structure that contains the subscription ID and the MO description. This example enables the graceful restart helper functionality. The system provides detailed information about each fault referemce. In Figure 3, the example object has three processes nexua write to property chunks in the object.
The commands keyword configures authorization sources for all EXEC commands, and the config-commands keyword configures authorization sources for all configuration commands.
Components in the instance include incompatible firmware versions. One can make changes on a single object or an object subtree. Three expert authors draw on deep experience with large Cisco customers, emphasizing the most common issues in real-world deployments, including problems that have caused major data center outages.
One can view faults using the API query methods to search for fault MOs, which can be of class fault: Every managed object in the system can be identified by a unique distinguished name DN. A record object contains a complete ccommand of the fault instance object and is logically organized as a flat list under a single container. For example, user can set fault thresholds on statistical measurements such as data traffic, temperatures etc.
