The Cisco® Catalyst® 3750-X and 3560-X Series Switches are an enterprise-class lines of stackable and standalone switches, respectively. These switches provide high availability, scalability, security, energy efficiency, and ease of operation with innovative features such as Cisco StackPower (available only on the Catalyst 3750‑X), IEEE 802.3at Power over Ethernet Plus (PoE+) configurations, optional network modules, redundant power supplies, and Media Access Control Security (MACsec) features. The Cisco Catalyst 3750-X Series with StackWise® Plus technology provides scalability, ease of management and investment protection for the evolving business needs. The Cisco Catalyst 3750-X and 3560-X enhance productivity by enabling applications such as IP telephony, wireless, and video for borderless network experience.Cisco Catalyst 3750-X and 3560-X Series primary features:- 24 and 48 10/100/1000 PoE+, non-PoE models, and 12 and 24 GE SFP port models - 24 and 48 10/100/1000 UPOE-capable models with Energy Efficient Ethernet (EEE) support - Four optional uplink network modules with GE or 10GE ports - Industry first PoE+ with 30W power on all ports in 1 rack unit (RU) form factor - Dual redundant, modular power supplies and fans - Media Access Control Security (MACsec) hardware-based encryption - Flexible NetFlow and switch-to-switch hardware encryption with the Service Module uplink - Open Shortest Path First (OSPF) for routed access in IP Base image - IPv4 and IPv6 routing, Multicast routing, advanced quality of service (QoS), and security features in hardware - Enhanced limited lifetime warranty (LLW) with next business day (NBD) advance hardware replacement and 90 day access to Cisco Technical Assistance Center (TAC) support - Enhanced Cisco EnergyWise for operational cost optimization by measuring actual power consumption of the PoE devices, reporting, and reducing energy consumption across the network - USB Type-A and Type-B ports for storage and console respectively and an out-of-band Ethernet management portIn addition to the above features, the Cisco Catalyst 3750-X switches also offer:- Cisco StackPower™ technology: An innovative feature and industry first for sharing power among stack members - Cisco StackWise Plus technology for ease of use and resiliency with 64 Gbps of throughput - Investment protection with backward compatibility with all other models of Cisco Catalyst 3750 Series SwitchesSwitch ConfigurationsAll switch models can be configured with four optional network modules. The UPOE, PoE+, and non-PoE switch models are available with either the LAN Base or IP Base feature set. IP Services feature set is available as an upgrade option at the time of ordering or through a license at a later time. The GE SFP switch models are available with either IP Base or IP Services feature set.Cisco Catalyst 3750-X and 3560-X Series SoftwareIn addition to IP Base and IP Services feature sets, the Cisco Catalyst 3750-X and 3560-X Series come with a new LAN Base feature set. The three feature sets available with all Cisco Catalyst 3750-X and 3560-X Series Switches are:- LAN Base: enterprise access Layer 2 switching features - IP Base: baseline enterprise access Layer 3 switching features - IP Services: advanced Layer 3 switching (IPv4 and IPv6) featuresThe LAN Base feature set includes comprehensive Layer 2 features, with up-to 255 VLANs. The IP Base feature set provides baseline enterprise services in addition to all LAN Base features, with 1K VLANs. IP Base also includes the support for routed access, StackPower (available only on the Catalyst 3750-X), MACsec, and the new Cisco Service Module. The IP Services feature set provides full enterprise services that includes advanced Layer 3 features such as Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6. All software feature sets support advanced security, QoS, and management features.The Cisco Catalyst 3750-X Series Switches with LAN Base feature set can only stack with other Cisco Catalyst 3750‑X Series LAN Base switches. A mixed stack of LAN Base switch with IP Base or IP Services features set is not supported.Customers can transparently upgrade the software feature set in the Cisco Catalyst 3750-X and 3560-X Series Switches through Cisco IOS® Software activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is powered on. Based on the license’s type, Cisco IOS Software activates the appropriate feature set. License types can be changed, or upgraded, to activate a different feature set.
