Read the first 7 AOS-CX VSF and VSX flashcards as text
What is the recommended minimum link speed for the AOS-CX VSX Inter-Switch Link (ISL) in a production deployment?
Answer: 10 Gbps per member link
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.
In VSX, which routing protocol adjacencies are synchronized across the ISL so both peers maintain consistent routing tables?
Answer: OSPF, BGP, and connected routes
VSX synchronizes OSPF, BGP, and connected-route information between peers so both switches maintain identical RIBs and can forward traffic locally.
When deploying VSX Active Gateway, which two items must be configured identically on both VSX peers?
Answer: Active Gateway virtual IP and virtual MAC
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.
Which statement correctly describes VSF versus VSX in terms of management plane?
Answer: VSF has one management IP shared across all members; VSX has independent management IPs per switch
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.
What is the effect of removing the ISL port-channel from a VSX configuration while the system is live?
Answer: VSX enters split-brain mode immediately
Removing the ISL port-channel while live breaks state synchronization and peer connectivity, triggering split-brain behavior where the Secondary shuts its MCLAG interfaces.
In AOS-CX VSF, how are software upgrades handled across the stack?
Answer: The conductor distributes the image to all members and the entire stack reboots together
VSF performs a unified upgrade where the conductor pushes the image to all members and the entire stack reloads simultaneously, maintaining a single software version.
Which VSX configuration element uses the out-of-band management network (OOBM) as its recommended transport?
Answer: VSX keepalive link
The VSX keepalive link is recommended to use the OOBM network so it remains reachable even when all in-band ISL paths fail, ensuring accurate split-brain detection.
