based management, Power over Ethernet (PoE) and other features.
To ensure optimal use of the network bandwidth and deliver maximum
voice and data quality, traffic flow can be directed according to the
needs of the business using Spanning Tree and Rapid Spanning Tree,
traffic prioritization, priority queuing and VLANs.

Link aggregation can be done via IEEE 802.3ad LACP or manually,
allowing ports to be grouped together to form an ultra-high-bandwidth
connection that greatly expands bandwidth capacity to the network core
or other parts of the network.

Baseline Switch 2900 models are available with 16, 24 and 48 ports; a
24-port PoE version delivers data and power over the same cabling. Each
switch also has four dual-purpose ports (configurable as 10/100/1000
copper or SFP-based fiber) to connect to high-performance computers,
servers, or network backbones.

ENTERPRISE-QUALITY SECURITY
Enterprise-quality security is provided with IEEE 802.1X network login
and advanced Access Control Lists (ACLs), which enable usage policies
via the switch at each point of access to the network. All management
communications are encrypted with HTTPS.
