To create an SVI using NX-API CLI JSON-RPC interface, one would typically need to construct a Python dictionary that represents the RPC payload containing the necessary commands. The request call would then be made using a library like requests where this dictionary is passed as JSON data. In general terms, without specifying exact options since they are not visible in any provided resources or within my capabilities:

One option would likely involve specifying parameters for creating an SVI including its ID number.

Another option might involve setting specific attributes for the SVI such as name, description, or IP address. References :=

Kubernetes deployed with the ACI CNI plug-in offers Namespace Isolation and Cluster Isolation. Namespace Isolation segregates resources within the same cluster using Kubernetes namespaces, while Cluster Isolation ensures complete separation between different clusters. References:

 The Cisco UCS Director script module serves as a centralized repository within the UCS Director platform. It allows users to store custom scripts, Java archives (jars), and customized lists of values, which are crucial for creating or modifying workflows to automate tasks in a data center environment. By utilizing the script module, administrators can enhance workflow functionality with their own scripts or existing ones, thereby streamlining operations.

 The ucs_vlans module is part of the Ansible collection for Cisco UCS (Unified Computing System) and is used to manage VLANs on Cisco UCS Manager. When working with Cisco UCS, VLANs are a crucial aspect of network segmentation and management. The ucs_vlans module allows users to configure VLAN settings such as the VLAN ID, name, and state. It also supports advanced features like fabric configuration and multicast policies.

In Cisco NX-OS platforms, two common bootstrap technologies are supported: iPXE (Internet Protocol eXtensible Environment) and POAP (PowerOn Auto Provisioning). iPXE allows for network booting using software such as DHCP or TFTP to load an operating system over a network interface independently of data storage devices like hard disks or CD-ROM drives. POAP automates the process of upgrading software images and installing configuration files on switches that are being deployed in the network for the first time. References := Cisco NX-OS Software

Step 1 : The switch searches for a Domain Host Configuration Protocol service on the network

Step 2 : DHCP assigns the switch an IP Address, default gateway, and IP address that are tracked by the Domain Name System server.

Step 3 : POAP gets the IP address of a script server, downloads the correct script for the switch, and runs the script on the switch.

To enable the REST API browser within Cisco UCS Director, a user must edit their profile to enable developer options. This action provides access to the REST API browser, which is a powerful tool for automating tasks and operations within the Cisco UCS Director environment.

 The Cisco UCS PowerTool is a PowerShell module that provides an interface to Cisco Unified Computing System (UCS) Manager API. To initiate a connection to the Cisco UCS Manager, the ‘Connect-Ucs’ cmdlet is used. This cmdlet requires parameters such as the name of the UCS domain (in this case, ‘myucsm.example.com’) and credentials stored in a variable (here represented as ‘$ucsm_creds’). The credentials are typically created beforehand using the ‘New-Object’ cmdlet with a PSCredential object type, which securely stores the username and password required for authentication. References := Cisco UCS PowerTool Suite - PowerShell Libraries for Cisco UCS Manager

Cisco NX-OS iPXE supports both IPv4 and IPv6 network protocols. iPXE is an open-source network boot firmware that enhances the capabilities of the standard PXE by supporting additional protocols like HTTP and TFTP, which can operate over both IPv4 and IPv6 networks3.

 To update the firmware on a specific Cisco UCS rack server managed by Cisco Intersight using a Python script, the script must include a GET request to retrieve the server with the specified AssetTag and then update the firmware JSON body with the server’s Managed Object ID (Moid). The correct statements to complete this task would be:

A GET request that queries the Intersight API for the server with the given AssetTag (Option A).

An update to the firmware JSON body dictionary, setting the ‘Server’ key to the ‘Moid’ value obtained from the GET request response (Option D).

 To retrieve server profiles with “WEST15” in the name, the correct GET API request is D. GET https://intersight.com/api/v1/server/Profiles?$select=Name &$filter=startswith(Name, ‘WEST15’). This request filters the server profiles to only those that start with “WEST15”. For updating the name, option E is correct. The BODY = {” Name”: sp_name.replace(‘WEST15’,’LXT14’)} uses the Python replace method to change “WEST15” to “LXT14” in the server profile name. References: Cisco Intersight API documentation and Python programming resources.

The top level in the ACI Management Information Tree is polUni. This is the top-level class for all policy definition and resolution objects within the Cisco ACI Policy Model. It serves as the root for policy namespace in the Management Information Tree12.

 In order to integrate a Kubernetes environment with Cisco ACI, the Kubernetes manifests typically need to include references to ACI End Point Groups (EPGs). This allows for the application components within Kubernetes to be associated with the networking policies defined in ACI, ensuring consistent network policy application across both environments. References: Since I can’t provide direct links to external sources, I recommend checking Cisco’s official documentation and training materials for the most accurate and up-to-date information.
