When configuring OSPF on a point-to-point network type (typically a direct link between two routers), OSPF treats the link as a broadcast-less point-to-point segment.

This reduces unnecessary OSPF overhead by eliminating the need for:

DR/BDR elections (which generate LSA Type 2 advertisements for broadcast multi-access networks).

Thus, changing network type to point-to-point reduces the number of LSA Type-2 advertisements, which are used to describe the network segment in multi-access environments.

No impact on number of routes (LSA Type-3 is about inter-area routes).

The default is usually broadcast or point-to-multipoint depending on interface.

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.

OSPF neighbors not forming adjacency and stuck in the 2WAY state typically indicates that the interface is set to passive mode, preventing OSPF Hello packets from being sent or received on that interface.

Removing passive mode on VLAN 182 allows OSPF Hello messages to be exchanged and adjacency to form.

Options involving network type or costs do not affect adjacency states related to passive interfaces.

The max-metric router-lsa on-startup affects LSA advertisements, not adjacency formation.

Therefore, the fix is to configure no passive-interface vlan182.

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.

When deploying a new Aruba CX 8325 switch to provide gateway and routing services, the L3-apg profile (Layer 3 Aggregation Profile) should be selected instead of the factory default. This profile is designed for switches acting as aggregation or core routers, enabling Layer 3 routing capabilities and optimized configurations for such roles.

The Spine profile (factory default) is optimized for leaf/spine architectures, but may not be ideal for aggregation gateways.

Leaf and L3-core profiles are targeted for different roles.

Using the L3-apg profile helps to ensure the switch is correctly optimized for Layer 3 gateway functions.

Configuring LACP link aggregation on two Aruba CX 6200M VSF switches requires configuring matching LAG settings on both switches, including LACP mode, LAG ID, and interfaces involved. Option C represents a correct configuration example using Aruba’s stacking/clustering technologies to create LAGs that utilize redundant ports from both switches.

The other options either have incorrect syntax, missing LACP parameters, or do not align with VSF cluster best practices for LAG.

The correct LAG setup ensures link redundancy, load balancing, and failover between aggregation and access switches.

LACP (Link Aggregation Control Protocol) modes can be active or passive. When two switches are both configured in passive mode, no LACP packets are initiated, causing the link aggregation to fail or go into a block state.

Changing one side from passive to active causes that switch to initiate LACP negotiation, resolving the block state.

Changing to static mode disables LACP negotiation, which is not recommended unless both sides are static.

Changing timeout does not solve LACP block issues caused by mode mismatches.

Therefore, changing one switch’s LACP mode from passive to active is necessary to resolve the block.

For an interface connected to an untrusted device regarding DSCP markings, the recommended configurations are:

Apply a classifier-based policy to assign a Local Priority value (Option B). This overrides or marks traffic based on predefined criteria.

Configure qos trust none (Option E) to disable trusting DSCP or CoS markings from the device, preventing manipulation of QoS.

Trusting CoS (Option A) is incorrect because the device is untrusted.

DSCP maps and Weighted Fair Queuing (Options C and D) are additional QoS features but do not specifically address untrusted markings.

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.

When troubleshooting downloadable user roles (DUR) between Aruba CX switches and ClearPass, it is crucial to verify the Trust Anchor profile on the switch. The Trust Anchor profile contains the certificates and keys that allow secure communication and authentication with ClearPass, ensuring the switch can validate the RADIUS server and downloaded user role information.

SNMP community string (Option A) is unrelated to DUR.

User-role configuration (Option B) is important but verifying trust anchor ensures secure role downloads.

HTTPS client certificate (Option C) is not typically part of DUR authentication.

Therefore, the Trust Anchor profile must be verified.
