ACSP Switch Configuration & Management 4

Question 1

What is the function of VSX (Virtual Switching Extension) on Aruba AOS-CX switches?

Accepted Answer

Pairs two switches to provide active-active redundancy with a shared control plane

Answer

VSX pairs two AOS-CX switches in an active-active configuration, providing redundancy and load-balancing without a stacking cable.

Question 2

Which link in a VSX setup carries inter-switch protocol messages and data traffic during failover?

Accepted Answer

ISL (Inter-Switch Link)

Answer

The ISL (Inter-Switch Link) in a VSX pair carries both control plane synchronization traffic and data traffic that must cross between the two VSX peers.

Question 3

In Aruba AOS-CX, what is a 'profile' used for in the context of switch management?

Accepted Answer

Groups configuration settings that can be applied to multiple interfaces at once

Answer

In AOS-CX, profiles allow administrators to define reusable configuration templates that can be applied consistently across multiple interfaces.

Question 4

Which spanning tree mode is recommended for use with VSX deployments on Aruba AOS-CX?

Accepted Answer

MSTP (802.1s)

Answer

MSTP (Multiple Spanning Tree Protocol, 802.1s) is recommended in VSX environments because it provides efficient topology management across multiple VLANs.

Question 5

What happens to traffic on a VSX setup when the ISL fails but both switches remain operational?

Accepted Answer

The secondary switch shuts down all its access ports to prevent split-brain loops

Answer

If the ISL fails while both VSX peers are still alive, the secondary switch disables its access ports to avoid a split-brain loop scenario.
