ACSP AOS-CX VSF and VSX 4

Question 1

What is the recommended minimum link speed for the AOS-CX VSX Inter-Switch Link (ISL) in a production deployment?

Accepted Answer

10 Gbps per member link

Answer

Aruba recommends at least 10 Gbps per member link on the ISL LAG to handle synchronized state and potential data traffic without becoming a bottleneck.

Question 2

In VSX, which routing protocol adjacencies are synchronized across the ISL so both peers maintain consistent routing tables?

Accepted Answer

OSPF, BGP, and connected routes

Answer

VSX synchronizes OSPF, BGP, and connected-route information between peers so both switches maintain identical RIBs and can forward traffic locally.

Question 3

When deploying VSX Active Gateway, which two items must be configured identically on both VSX peers?

Accepted Answer

Active Gateway virtual IP and virtual MAC

Answer

Both VSX peers must share the same Active Gateway virtual IP and virtual MAC so hosts see a single gateway regardless of which peer handles the traffic.

Question 4

Which statement correctly describes VSF versus VSX in terms of management plane?

Accepted Answer

VSF has one management IP shared across all members; VSX has independent management IPs per switch

Answer

VSF presents the entire stack as one logical switch with a single management IP, while VSX peers remain independent switches each with their own management interface.

Question 5

What is the effect of removing the ISL port-channel from a VSX configuration while the system is live?

Accepted Answer

VSX enters split-brain mode immediately

Answer

Removing the ISL port-channel while live breaks state synchronization and peer connectivity, triggering split-brain behavior where the Secondary shuts its MCLAG interfaces.
