Cisco Catalyst 2960 Series Intelligent Ethernet Switches are a new family of fixed-configuration standalone devices that provide desktop Fast
Ethernet and Gigabit Ethernet connectivity, enabling enhanced LAN services for entry-level enterprise, mid-market, and branch office networks.
The Catalyst 2960 Series offers integrated security, including network admission control (NAC), advanced quality of service (QoS), and

The Cisco Catalyst 2960 Series software image is a rich suite of intelligent services, including advanced QoS, rate limiting, and ACLs. The SFP- based Gigabit Ethernet ports accommodate a range of SFP transceivers, including the Cisco 1000BASE-SX, 1000BASE-LX, 1000BASE-BX, 1000BASE-ZX, 100BASE-FX, 100BASE-LX, 100BASE-BX, and coarse wavelength-division multiplexing (CWDM) SFP transceivers. GIGABIT ETHERNET At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet new and evolvi

Port security can be used to limit access on an Ethernet port based on the MAC address of the device to which it is connected. It also can be used to limit the total number of devices plugged into a switch port, thereby protecting the switch from a MAC flooding attack as well as reducing the risks of rogue wireless access points or hubs. With Dynamic Host Configuration Protocol (DHCP) snooping, DHCP spoofing can be thwarted by allowing only DHCP requests (but not responses) from untrusted

These QoS features allow network administrators to prioritize mission-critical and bandwidth-intensive traffic, such as enterprise resource planning (ERP), voice (IP telephony traffic), and computer-aided design and manufacturing (CAD/CAM), over applications such as FTP or e-mail. For example, it would be undesirable to have a large file download destined to one port on a switch increase latency in voice traffic destined to another port on this switch. This condition is avoided by ensuring
