24-Port Gigabit Switch Cisco SGE2000-G5
The Cisco SGE2000 24-Port Gigabit Switch (Figure 1) helps maximize system availability, with fully redundant stacking and dual images for resilient firmware upgrades. The switch helps secure the network through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, access control lists (ACLs), denial-of-service (DoS) prevention, and MAC-based filtering. The enhanced quality of service (QoS) and traffic-management features help ensure clear and reliable voice and video communications.
The Cisco SGE2000 includes an intuitive, secure management interface, enabling you to take advantage of the comprehensive feature set for a better-optimized, more secure network.
Features
