Distributed link aggregation: Link aggregation groups (LAG) with physical ports may be shared across members of an ArubaStack. This distribution of a LAG across the ArubaStack allows load-sharing and redundant connections across multiple devices, providing an additional level of reliability and maximum availability.
PoE priority: ArubaOS PoE priority classifies attached PoE devices with a priority level, ensuring no loss of power for business-critical devices like APs, security cameras and red phones.
Hot Standby Link (HSL): ArubaOS HSL provides a simplified link failover mechanism without configuring and running the spanning-tree protocol. A port or group of ports may be configured as redundant for another port or group of ports
ArubaStack with S3500: All S2500 models may be a member of an ArubaStack concurrently with S3500 models. The S3500, with its redundant power and fieldreplaceable fan tray, provides an added level of hardware availability for network- critical devices.
