Cisco WS-C2960G-48TC-L Catalyst 2960G-48TC Network Switch
Cisco® Catalyst® 2960 Series Switches with LAN Base software are a family of fixedconfiguration, standalone intelligent Ethernet devices that provide desktop Fast Ethernet and Gigabit Ethernet connectivity, enabling enhanced LAN services for entry-level enterprise, midmarket, and branch office networks. The Cisco Catalyst 2960 LAN Base Series offers integrated security, including Network Admission Control (NAC), advanced quality of service (QoS), and resiliency to deliver intelligent services for the network edge.

Gigabit Ethernet
At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet new and evolving network demands, alleviate bottlenecks, and boost performance while increasing the return on existing infrastructure investments. Today’s workers are placing higher demands on networks, running multiple concurrent applications. For example, a worker joins a team conference call through an IP videoconference, sends a 10-MB spreadsheet to meeting participants, broadcasts the latest marketing video for the team to evaluate, and queries the customer relationship management (CRM) database for the latest real-time feedback. Meanwhile, a multigigabyte system backup starts in the background and the latest virus updates are delivered to the client.

Enhanced Security
The wide range of security features that the Cisco Catalyst 2960 LAN Base Series offers helps businesses protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. The Cisco Identity-Based Networking Services (IBNS) solution provides authentication, access control, and security policy administration to secure network connectivity and resources. Cisco IBNS in the Cisco Catalyst 2960 LAN Base Series prevents unauthorized access and helps ensure that users get only their designated privileges. It provides the ability to dynamically administer granular levels of network access. Using the 802.1x standard and the Cisco Secure Access Control Server (ACS), users can be assigned a VLAN upon authentication, regardless of where they connect to the network. This setup allows IT departments to enable strong security policies without compromising user mobility, and with minimal administrative overhead.

To guard against denial-of-service (DoS) and other attacks, ACLs can be used to restrict access to sensitive portions of the network by denying packets based on source and destination MAC addresses, IP addresses, or TCP/User Datagram Protocol (UDP) ports. ACL lookups are done in hardware, so forwarding performance is not compromised when ACL-based security implemented.

Availability and Scalability
The Cisco Catalyst 2960 LAN Base Series is equipped with a large set of features that allow for network scalability and higher availability through multicast filtering as well as a complete suite of Spanning Tree Protocol enhancements aimed to maximize availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), UplinkFast, and PortFast, help to maximize network uptime. PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design. UplinkFast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Flexlink provides bidirectional, fast convergence in less than 100 milliseconds. The Loopguard and bridge protocol data unit (BPDU) guard enhancements provide Spanning Tree Protocol loop avoidance.

Advanced QoS
The Cisco Catalyst 2960 LAN Base Series offers superior multilayer QoS features to help ensure that network traffic is classified and prioritized and that congestion is avoided in the best possible manner. Configuration of QoS is greatly simplified through automatic QoS (Auto QoS), a feature that detects Cisco IP phones and automatically configures the switch for the appropriate classification and egress queuing. This optimizes traffic prioritization and network availability without the challenge of a complex configuration. The Cisco Catalyst 2960 LAN Base Series can classify, reclassify, police, mark, queue, and schedule incoming packets and can queue and schedule packets at egress. Packet classification allows the network elements to discriminate between various traffic flows and enforce policies based on Layer 2 and Layer 3 QoS fields.
