24-Port 10/100Mbps Ethernet Switch Cisco SFE2000-G5
The Cisco® SFE2000 24-Port 10/100 Ethernet Switch is optimized to maximize system availability, with fully redundant stacking, redundant power options, and dual images for resilient firmware upgrades. The Cisco SFE2000 is able to 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 QoS and traffic management features help ensure clear and reliable voice and video communications.
The Cisco SFE2000 provides an intuitive, secure management interface, enabling you to better utilize the switch’s comprehensive feature set, resulting in a better-optimized, more secure network.
Features
- Twenty-four 10/100 Ethernet ports plus four 10/100/1000Mbps copper ports
- Two Small Form-Factor Pluggable (SFP) slots (shared with two copper ports) for fiber Gigabit Ethernet expansion
- Dual images for resilient firmware upgrades
- Up to 12.8-Gbps nonblocking, store-and-forward switching capacity
- Simplified quality of service (QoS) management using 802.1p, Differentiated Services (DiffServ), or type of service (ToS) traffic prioritization specifications
- Fully resilient stacking provides 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 Secure Sockets Layer (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
- Enhanced rate-limiting capabilities, including back pressure, multicast, and broadcast flood control
- Port mirroring for noninvasive monitoring of switch traffic
- Mini jumbo frame support (1600 bytes)
- Simple Network Management Protocol (SNMP) v1, v2c, v3 and Remote Monitoring (RMON) support
