Practise switch scenarios involving SW1, SW2, VLANs, trunk links, allowed VLAN lists and show interfaces trunk output.
Start Scenario PracticeA company is deploying FCoE in their data center. The design includes a Cisco Nexus 9000 switch with FEX modules. The storage team insists on using dedicated FCoE VLANs. Which best practice should be followed to ensure lossless behavior for FCoE traffic?
Explanation: FCoE requires lossless transport to prevent frame drops that could corrupt Fibre Channel frames. Priority Flow Control (PFC), defined in IEEE 802.1Qbb, enables pause frames on a per-priority basis, allowing the FCoE VLAN to be configured with a dedicated priority class that receives no-drop treatment. On Cisco Nexus 9000 switches, this is achieved by enabling PFC on the specific VLAN used for FCoE traffic, ensuring lossless behavior without affecting other traffic classes.
A data center has 100 Nexus switches in a fabric managed by Cisco Nexus Dashboard Orchestrator (NDO). The network team needs to automate the creation of a new network template that includes multiple VLANs and VRF configurations. They want to ensure that the template is applied consistently across all leaf switches without manual intervention. The engineer writes a Python script using the NDO REST API to create the template and deploy it. However, the deployment fails with an error 'Template validation failed: overlapping IP subnets'. Upon reviewing the template, the engineer notices that two VLANs have overlapping subnet definitions. Which action should the engineer take to resolve this issue efficiently?
Explanation: The root cause of the deployment failure is overlapping IP subnets in the template definition. Manually correcting the overlapping subnets in the template and re-running the deployment script directly resolves the validation error without introducing unnecessary complexity or risk. This approach ensures the template is valid before deployment, maintaining consistency across all leaf switches.
In the context of Ansible automation for Cisco Nexus switches, which module can be used to manage VLAN configurations?
Explanation: The cisco.nxos collection includes the nxos_vlan module specifically for managing VLANs on NX-OS devices.
Ansible playbook that deploys VLANs on NX-OS fails on a particular switch with 'privilege escalation required'. What should be checked first?
Explanation: The error 'privilege escalation required' indicates that Ansible cannot execute commands with the necessary elevated privileges on the NX-OS switch. In Ansible, privilege escalation is handled via the 'become' mechanism, and for network devices like NX-OS, the 'ansible_become_password' (or 'enable' password) is required to enter privileged EXEC mode. Without this password, Ansible remains in user EXEC mode, which lacks the authority to apply VLAN configurations.
Refer to the exhibit. An automation script queries the Cisco Nexus 9000 using the NX-API JSON format and receives the above output. The script is designed to validate that interface Eth1/1 is in access mode with VLAN 100. However, the script reports a failure. What is the most likely reason?
Explanation: The NX-API returns all values as strings in JSON output, including numeric fields like VLAN IDs. If the script uses strict type checking (e.g., `===` in Python or JavaScript), comparing the string '100' to the integer 100 will fail, even though the interface is correctly configured in access mode with VLAN 100. This is a common pitfall when parsing NX-API responses without explicit type conversion.
