The LACP state event Actor state: ALFNCD, Partner state: ASFNCD indicates that the LACP negotiation between the local (actor) and peer (partner) is successful with all flags matching and no errors.

ALFNCD and ASFNCD are standard LACP states indicating Active, Long timeout, Aggregation capable, Not synchronized, Collecting, and Distributing flags set as expected.

Also, the log shows the LACP rate is set to slow, which is the default.

Thus, the output shows the LAG 253 has a matching LACP configuration with its peer.

The command erase all zeroize performs a secure erase on the switch, which deletes all customer data including startup-config and stored credentials. This process can take up to an hour depending on the hardware and storage media.

It does not retain running config (Option A).

It does not restore the factory AOS-CX image (Option B).

Admin credentials are deleted as part of the secure erase (Option C is incorrect).

Therefore, this command securely wipes all data and resets the device.

The troubleshooting methodology exemplified by comparing outputs or configurations to find discrepancies is called Spot the difference. It involves checking variations between working and non-working states or devices.

Follow the path: tracing packet flow step-by-step.

Top-down/Bottom-up: analyzing layers systematically.

Replace configuration: swapping configurations to isolate issues.

Here, comparing command outputs aligns with spot-the-difference.

The issue is VMware vMotion traffic on VLAN 3903 failing, while other VLANs work normally. vMotion traffic requires support for larger frame sizes (jumbo frames) because vMotion packets are large and benefit from increased MTU to improve performance and reduce fragmentation.

Configuring jumbo frames on VLAN 3903 ensures that frames on this VLAN can use an MTU larger than the default 1500 bytes.

Configuring jumbo on the interface alone may not be sufficient if the VLAN itself is not set to support jumbo frames.

Setting MTU on VLAN or interface might not work unless jumbo frames are enabled.

During a VSX firmware upgrade, the vsx-syned process stops synchronization while the switches have mismatched software versions. Synchronization resumes once both switches run the same software.

VSX synchronization cannot continue while versions mismatch (contrary to options B and D).

Compatibility mode is not required before rebooting secondary switch (Option D incorrect).

This behavior ensures consistency and avoids split-brain during upgrades.

Valid Network Analytics Engine (NAE) agent actions include:

Running CLI commands (Option A), allowing automated command execution for remediation or data collection.

Generating local system logs (Option C) for event tracking and audit purposes.

Other options:

Generating SNMP traps (B) and starting/stopping packet captures (D) are not typical NAE actions.

Creating a new TAC case (E) is an external process, not an automated NAE action.

When a VSX primary switch is powered off, it loses connectivity with management systems such as HPE Aruba Central. This causes the management system to trigger a "Switch Disconnected" alert because the switch is no longer reachable.

"Switch Reboot" alerts would indicate a restart, not power off.

"Switch Stack Conductor Change" refers to stack leadership changes, not VSX primary down.

"Switch STP Root Change" relates to Spanning Tree Protocol root bridge changes.

Hence, powering off the VSX primary causes a "Switch Disconnected" alert.

To isolate wired ports on the same VLAN on a large scale (such as hotel rooms) but allow communication within the same VLAN for common areas, Private VLANs (PVLANs) are recommended. PVLANs allow segmentation within a single VLAN by dividing it into primary and secondary VLANs, controlling communication between ports.

VPN and VXLAN are overlay technologies for different purposes.

UBT (User-Based Tunneling) is related to wireless user segmentation, not wired port isolation.

Therefore, PVLANs provide the simplest and most effective solution to isolate room ports within a single VLAN.

To determine which sites would benefit most from upgrading from 6200 to more powerful 6300 switches in Aruba Central, the best report to run is the Switch Capacity Planning report. It analyzes resource utilization and capacity to identify bottlenecks and potential upgrade candidates.

Infra Inventory lists devices but not capacity usage.

Resource Utilization gives raw usage but not in planning context.

Network report focuses on topology and status.

Hence, Switch Capacity Planning is the most relevant report for upgrade planning.
