Wire-speed performance at high 1GbE, 10GbE, and 40GbE port densities dramatically simplifies network topologies and operations.
3. Eight QoS Queues
Eight QoS queues per switch port ensure proper prioritization of voice, video, and multiple levels of data traffic, with room to converge other networks, such as building automation and video security systems.
4. Innovative Switch Design
Innovative, cost-effective switch design enables new architectures that reduce cost and complexity, while unified management and automation tools consolidate system monitoring.
5. Virtual Chassis
Virtual Chassis technology allows multiple interconnected switches to operate as a single logical device, reducing operational expenses and simplifying management.
6. Near Line-Rate Encryption
Support for IEEE 802.1ae Media Access Control Security (MACsec) for link-layer data confidentiality, data integrity, and data origin authentication enables 88 Gbps of near line-rate, hardware-based traffic encryption on all 1GbE and 10GbE ports.
