Product Overview

The Cisco^® SGE2000P 24-Port Gigabit Switch (Figure 1) helps maximize system availability, with fully redundant stacking, redundant power options, 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 (ACL), denial-of-service (DoS) prevention, and MAC-based filtering. The enhanced quality of service (QoS) and traffic-management features help ensure clear and reliable IP voice and video communications.

For wireless or voice over IP (VoIP) deployments, the Cisco SGE2000P supports the IEEE802.3af standard for Power over Ethernet (PoE). Automatic load sensing in the power control circuitry automatically detects PoE on the end device before providing power. For safety, each port has independent overload and short-circuit protection, along with LED indicators for power status. A maximum of 15.4W is available on the Fast Ethernet ports for powering PoE-enabled wireless access points or VoIP handsets, with a maximum per-device PoE delivery of 185W available for all ports.

The Cisco SGE2000P provides an intuitive, secure management interface, enabling network administrators to better utilize its comprehensive management feature set, for a better-optimized and more secure network.

• Dual images for resilient firmware upgrades

• 48-Gbps, nonblocking, store-and-forward switching capacity

• Simplified QoS management using 802.1p, Differentiated Services (DiffServ), or type of service (ToS) traffic prioritization specifications

• Power redundancy when used with Cisco RPS1000 380W Redundant Power Supply Unit

• Fully resilient stacking for optimized growth with simplified management

• ACLs for granular security and QoS implementation

• Can be configured and monitored from a standard web browser

• Secure remote management of the switch via Secure Shell (SSH) and SSL encryption

• 802.1Q-based VLANs enable segmentation of networks for improved performance and security

• Private VLAN Edge (PVE) for simplified network isolation of guest connections or autonomous networks

• Automatic configuration of VLANs across multiple switches through Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)

• User/network port-level security via 802.1X authentication and MAC-based filtering

• Increased bandwidth and added link redundancy with Link Aggregation Control Protocol (LACP)

• Enhanced rate-limiting capabilities, including back pressure and multicast and broadcast flood control

• Port mirroring for noninvasive monitoring of switch traffic

• Jumbo frame support up to 10KB
