The Cisco Catalyst 3750 v2 series switches are next-generation energy-efficient Layer 3 Fast Ethernet stackable switches. This series of switches supports Cisco EnergyWise technology, which enables companies to measure and manage power consumption of network infrastructure and network-attached devices, thereby reducing their energy costs and their carbon footprints. The Cisco Catalyst 3750 v2 series consumes less power than its predecessors and is the ideal access layer for enterprise, retail, and branch-office environments, as it increases productivity and investment protection by enabling a unified network for data, voice, and video.

Enhanced security
With the wide range of security features, such as ACLs, authentication, port-level security, and identity-based network services (IBNS) with IEEE 802.1x and extensions that the Cisco Catalyst 3750 v2 series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation.

Availability and scalability
The Cisco Catalyst 3750 v2 series is equipped with a robust set of features that allow network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements that help increase availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), Uplink Fast, and PortFast, increase network uptime. PVST+ allows Layer 2 load sharing on redundant links to efficiently use the additional capacity inherent in a redundant design. Uplink Fast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Loop guard and BPDU guard provide Spanning Tree Protocol loop avoidance.

High-performance IP routing
Cisco Catalyst 3750 v2 series switches deliver high-performance, hardware-based IP routing. The Cisco Express Forwarding (CEF/dCEF) routing architecture enables outstanding scalability and performance. Implementation of routed uplinks to the core improves network availability by enabling faster failover protection and simplifying the Spanning Tree Protocol algorithm by terminating all Spanning Tree Protocol instances at the aggregator switch. If one of the uplinks fails, quicker failover to the redundant uplink can be achieved with a scalable routing protocol such as Open Shortest Path First (OSPF) or Enhanced Interior Gateway Routing Protocol (EIGRP) rather than relying on standard Spanning Tree Protocol convergence. Redirection of a packet after a link failure using a routing protocol results in faster failover than a solution that uses Layer 2 spanning-tree enhancements. Additionally, routed uplinks allow better bandwidth use by implementing ECR on the uplinks to perform load balancing. Routed uplinks optimize the utility of uplinks out of the LAN by eliminating unnecessary broadcast data flows into the network backbone.
-
Advanced QoS
The Cisco Catalyst 3750 v2 series offers superior multilayer, granular 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 Auto-QoS, a feature that detects Cisco IP Phones and automatically configures the switch for the appropriate classification and egress queuing.
-
Management and control functions
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software revision running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
