Product Overview

The Cisco^® SFE2010P 48-Port 10/100 Ethernet Switch (Figure 1) allows you to expand your network securely. It is optimized for maximum system availability, with fully redundant stacking, redundant power options, and dual images for resilient firmware upgrades. Network security is provided through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, access control lists (ACLs), denial-of-service (DoS) prevention, and MAC-based filtering. Web-based configuration is secured using SSL. The enhanced quality of service (QoS) and traffic-management features help ensure clear and reliable voice and video communications.

For wireless or voice over IP (VoIP) deployments, the Cisco SFE2010P supports the IEEE 802.3af standard for Power over Ethernet (PoE). Automatic load sensing in the power-control circuitry detects PoE on the end device before providing power. For safety, each port has independent overload and short-circuit protection, along with LED indicators to show power status. The switch provides 15W of available PoE power on up to 24 of the Fast Ethernet ports for powering PoE-enabled wireless access points or VoIP handsets. The maximum PoE available per switch for all ports is 360W

The Cisco SFE2010P provides resilient stacking for up to four units, or 192 ports. A stack of units is managed as a single switch with one web management interface. The SFE2010P switch can coexist in a stack with the Cisco SFE2000 and SFE2000P 24-Port 10/100 Ethernet Switches and the Cisco SFE2010 48-Port 10/100 Ethernet Switch, for a maximum of 192 ports in a stack. The stacking capability includes master/backup unit behavior, ring and chain architecture, and hot insertion and removal of units.

Software running on the Cisco SFE2010P switch interacts with provisioning, management, and security software on both the site's services router and the service provider's equipment. This interaction provides simple, one-step installation and access to web-administered features for the administrator and users. Simple, affordable network operations throughout the network's lifetime are the result.

Features

• 15.4W available power to the Fast Ethernet ports for PoE-enabled wireless access points or VoIP handsets (maximum per-switch PoE delivery of 360W available for all ports)

• Dual images for resilient firmware upgrades

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

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

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

• Fully resilient stacking for optimized growth with simplified management

• ACLs for granular security and QoS implementation

• Configuration and monitoring 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) simplifies 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

• Mini jumbo frame support (1632 bytes)

• Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support

• Fully rack mountable using included rack-mounting hardware
