ACSP AOS-CX VSF and VSX 2

Question 1

In a VSF stack, which member role is responsible for running the control plane and making forwarding decisions for the entire stack?

Accepted Answer

Conductor

Answer

The Conductor is the primary control-plane switch in a VSF stack, managing all forwarding and configuration for the virtual fabric.

Question 2

What is the maximum number of switches that can be combined in a single AOS-CX VSF stack?

Accepted Answer

8

Answer

AOS-CX VSF supports up to 8 members in a single virtual switching fabric.

Question 3

Which VSF topology provides the highest level of resiliency against a single link failure?

Accepted Answer

Ring

Answer

A ring topology connects the last VSF member back to the conductor, so any single link failure leaves all members connected via the remaining path.

Question 4

When a VSF stack splits due to a link failure, which mechanism prevents both partitions from simultaneously acting as the active conductor?

Accepted Answer

Multi-Active Detection (MAD)

Answer

MAD (Multi-Active Detection) uses a dedicated link or OOBM network to detect split-stack conditions and shut down the secondary partition.

Question 5

In AOS-CX VSF, what automatically happens to VSF member port numbering when a new switch joins as member 3?

Accepted Answer

Ports are renumbered starting from 3/1/1

Answer

VSF member ports are prefixed with the member number, so member 3's first port becomes 3/1/1, giving each member a unique port namespace.
