HPE7-A11: HPE Aruba Networking Certified Professional - Campus Access Architect

Lower access-to-aggregation oversubscription ratios preserve more uplink bandwidth and reduce the likelihood of congestion, which supports low-latency, highly available, mission-critical wireless traffic. Cisco’s campus design examples for 5GbE access-point deployments show realistic ratios of about 3.6:1 for a single access switch and 7.2:1 for an access-layer switch stack; therefore, 4:1 and 7:1 are appropriate starting points. Higher ratios increase the risk of transient uplink congestion.
