HIGH AVAILABILITY FEATURES
The S2500 includes a number of features that make it ideal to
deploy in networks that require maximum availability.
• 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.
